Antioxidant density of Hungarian kapia and red bell pepper varieties
80-84Views:151There is a lot of evidence that the pepper is one of the most important sources of vitamin C. Albert Szent-Györgyi was the first to extract ascorbic acid from a red bell pepper in the 1930s. Previously people had eaten vitamin C on the long voyage to protect against scurvy. Vitamin C is an important antioxidant, and it is a cell protector today. Vitamin C protects the cardiovascular system against infection. This vitamin decrease blood-pressure, a raises the HDL cholesterol level (good), and inhibits gout.
„Antioxidant density” is a biological value indicator obtained in synthetic way. „Antioxidant density” indicates the antioxidant capacity of a particular food, e. g. fruits and vegetables, related to 1 Calorie. In our study, we measured the total antioxidant capacity, vitamin C content and „antioxidant density” of Hungarian paprika varieties. -
Coherence and connection between the good pond culture practice and the environment conscious management
60-73Views:86According to the data indicating the decline and restructuring during the past decade, as well as the trend in the European Union member states, it can be expected that the role of traditional agriculture and fish production in direct rural employment decrease further. This also values those strategic directions for restructuring that will lead fishculture from quantity driven to quality production along with sustainable development (i.e. environmental conscious production) and multifunctional farming. This way the economic and social tensions caused by the concentration of the production and labour output can be mitigated.
It is laid in the 1257/1999 Act on rural Development that farmers that enrol the agri-environmental scheme should follow the “Good Agricultural Practice” on the whole managed area. In case of agri-environmental schemes this is a precondition for which no grants are given.
The adaptation of “Good Agricultural Practice” in fishproduction,where it is called: “Good Pond Culture Practice” is considered important on the basis of the above mentioned. This programme is undertaken in co-operation with the Research Institute for Aquaculture, Fisheries and Irrigation, University of Debrecen, Faculty of Agricultural Economics and Rural Development and the Association of Hungarian Fish Farmers and Product Council.
The European Commission proposed the formulation of the European Fisheries and Aquaculture Fund (EFAF) for the period 2007-20013, which will replace the Financial Instruments for Fisheries Guidance (FIFG), but it also consists of several new elements and will be working differently, too. According to the proposal the budget for the Fund will be nearly 5 billion EUR (4963 million EUR). The development level of aquaculture and fisheries and the social and economic significance in the given member state will be considered when distributing the Fund between the Member States.
According to the plan the Fund is organised along five priority axes, of which the most important for the Hungarian fisheries sector is No. II: Aquaculture and the processing and marketing of aquaculture and fisheries products. The main measure areas are the followings:
1. investment support for aquaculture;
2. support for aquatic-environmental schemes;
3. environmental- and animal health issues;
4. investments in processing and marketing
In case of accessing support under measure area No. 2 farms are obliged to meet the requirements of the scheme beyond the “good management practice” for 5 years, which is to be supervised by the approved body of the Member State. For this reason our work is considered to be substantial.
Approval of the application of “Good Pond Culture Practice” is based on two elements: first the prevailing environmental and nature conservation regulations, as well as the list of controllable conditions in the new agri-environmental agreements are to be met. “Good Pond Culture Practice” are to be conducted on the whole farm area. Its main elements are:
- nutrition management,
- feeding,
- pond maintenance,
- stocking,
- harvesting,
- animal welfare (storage and over-wintering). -
Cytochrome b diversity of Hungarian Botrytis cinerea strains
18-21Views:120In the mitochondrion of eukaryotes, cytochrome b is a component of respiratory chain complex III. Cytochrome b is encoded by the
cytochrome b (CYTB) gene located in the mitochondrial genome. The fungicidal activity of QoIs relies on their ability to inhibit mitochondrial respiration by binding at the so-called Qo site (the outer quinol-oxidation site) of the complex III. Since their introduction, QoIs (like azoxystrobin) have become essential components of plant disease control programs because of their wide-ranging efficacy against many agriculturally important fungal diseases like grey mould on various crops. QoI resistance primarily arises from a target-site-based mechanism involving mutations in the mitochondrial CYTB. As the management of grey mould is often dependent on chemicals, the rational design of control programs requires the information about the diversity of genes connected with resistance in field populations of the pathogen.
Monospore B. cinerea field isolates has been collected during 2008-2009 from different hosts in Hungary. PCR fragment length analysis
indicated the high frequency presence of type large intron in the isolates while in a few strains G143A substitution could also be detected.
These results indicated the heterogeneity of CYTB in the Hungarian B. cinerea populations, which possibly involve the heteroplasmy of this
mitochondrial gene, moreover indicates the existence op azoxystrobin resistant populations in Hungary.

Effect of different production types on the yield and ß-carotene content of sweet potato /cultivar Ásotthalmi- 12/
45-49Views:168Production of sweet potato is extending in Hungary, despite the fact that there is no field-specific production technology. Therefore, many growers cannot utilize potential yields and quality. The goal of this study was to determine the optimal production method of the Ásotthalmi 12, a Hungarian sweet potato cultivar which can adapt to the Hungarian climate. The effect of single and twin rows production on the yield of this cultivar was examined. The planting was carried out on June 24th, the harvesting on October 20th and the growing-season was 120 days long. Uniform nutrient supply was applied to the whole field experiment. During basic fertilization, 206 kg Knd 20 kg N, 36 kg P ha-1 were used on the soil. While forming the ridges, we used an additional 25 kg N, 45 kg P and 62.5 kg K ha-1. We adopted drip tape irrigation on the experimental field. After the planting, from the 8th week of the vegetation, another 21 kg ha-1 K, 10 kg ha-1 MgSO4, and 2 kg ha-1 Ca(NO3)2 was added in one dosage weekly, until the 13th week of vegetation. At the evaluation of the experiment, we examined the yield regarding the whole experimental plot. SPAD and fluorescence measurements were carried out on 08.16. 2019, 08.28.2019, and on 09.13.2019, during the watering break. To demonstrate the difference between the dates, we applied ANOVA and Tukey post-hoc tests. For the measurement of phytonutrients HPLC, a liquid chromatograph was used, where the carotenoid content of the Ásotthalmi 12 cultivar was determined in connection with the different production methods. Test results showed that twin rows production leads to a nearly 30% greater yield, than single row production. We determined, that the growth of yield correlates negatively to the ß-carotene content of the Ásotthalmi 12 cultivar sweet potato.

New and innovative consumer demands and expectations on the Hungarian food market
485-499Views:59Food and eating have always encompassed more than the simple intake of nutrients; therefore, when thinking about food consumption, we need to examine several groups of influencing factors whose correlations from the aspect of the consumer are described by a complicated matrix. This paper focuses on the selection of signs indicating new and innovative consumer behaviours, and on the megatrends that are the driving forces of transitions and that lead to the consequences of strikingly reconsidered consumer decisions nowadays. The authors stress that there are qualitative and structural changes in food consumption in Hungary, with an increasing quantity of differentiated consumer demands appearing, a few of them influencing our everyday decisions even at
the concept level. The findings of primary research originated from a personal questionnaire survey consisting of 2001 respondents, in which we also focused on the attitude towards eating and media consumption related to gastronomy.
This paper is an introduction to the market segments detectable in the present Hungarian population aged 15–74 in the topics concerned. -
The launch on the way to development or the „revival”... (Comparisons of theoretical and practical approaches apropos of the change and crisis management process of smes and mature companies) .
65-70Views:82Hungarian SMEs, just like those in other EU member states, often cease for various reasons. Among these factors are many, which should not necessarily turn out this way. These factors are studied in numerous countries while the attempt is also made to create the systems of conditions for these enterprises to recover – often through various aids and supports (from public supports to non-governmental initiatives). Among other things they are trying
to organize those services with the help of which – if there is the slightest hope for survival – those SMEs in trouble or having serious difficulties could avoid going down by recovering from
their problematic situation and getting improvements.
These days this issue comes up more and more urgently in Hungary, as well. It has quite a few signs indicating that – among other things – the reports, the enquiries and commissions of the
National Association of Change and Crisis Managers (VOE), all of which – just like "thermometers" – reflect this tendency well.
I have been doing research on this topic since 1993. As an expert I utilize them, and as a VOE member, vice president, then president I process the relevant Hungarian but mainly French
experience on the subject. I intend to present those few theoretical and practical results and applicable experience I have reached this way in this presentation of mine. -
Preparatory study for carbon sequestration modelling of agroforestry systems in Hungary: The assessment of the yield class distribution of windbreaks
73-78Views:83The escalating carbon dioxide emissions leading to global climate change are acknowledged as a paramount environmental challenge in the twenty-first century. The significance of land use systems in stabilising carbon dioxide levels and enhancing carbon sink potential has gained noteworthy attention from both the scientific and political communities. The Intergovernmental Panel on Climate Change emphasises that agroforestry systems present vital prospects for synergising climate change adaptation and mitigation efforts, offering substantial technical mitigation potential. Windbreaks are well-known agroforestry systems in Hungary and form an important part of agricultural landscapes. The improved agroforestry subsidy system in our country makes it relevant to model the carbon sequestration potential of windbreaks. In the framework of the ForestLab project we plan to develop a carbon sequestration model specific for Hungarian agroforestry systems. In this study, as a preparatory step of the model development, we assessed the yield class distribution of Hungarian windbreaks by tree species group and identified variables that had significant effect on yield class based on the data of the National Forestry Database. Our results show that among the examined effects the most important predictor of the yield class of windbreaks was the tree species group, followed by the thickness of the productive soil layer and the hydrology of the site.

Isolation and identification of endophytic fungi connected to Grapevine Diseases, from the Tokaj wine region, Hungary
61-66Views:224Grapevine Trunk Diseases (GTD) is one of the most important diseases in vineyards worldwide, which can be found in Hungarian vineyards as well. In Hungarian wine regions there is very little information about the occurrence of pathogens which cause GTD, in case of Tokaj wine region there is no knowledge about that, what kind of pathogens can be found in the vineyards.
The objective of our research is to assess the situation and occurrence of GTD in Tokaj wine region in cooperation with local specialists, as well as identification of pathogens which were isolated from the diseased trunks by morphological and genetic basis.
We were able to isolate endophytic fungi from all sampled grape trunk. The majority of them were determined as Diplodia seriata not only based on colony morphology, but also determined by rDNA sequences.

Mitigation and adaptation measures in the hungarian rural development programme
245-250Views:82In the Hungarian Rural Development Programme (RDP) climate change adaptation is addressed through the measures in Axis 1, 2, 3 and 4. Under Axis 1 farmers can receive support for farm modernisation that will help them adapt to climate change. The processing industry will also be able to use the available resources for capital expenditure on buildings and new equipment. Axis 2 and especially the soil and water package within the agrienvironmental
measure aim to support production methods, which protect soil quality and will help adaptation to climate change. Measures of Axis 3, such as basic services for the economy and rural population, village renewal and development will provide local communities the opportunity to identify actions that can be undertaken to deal with the effects of climate change. On the other hand, the extension of forest resources contributes to climate change mitigation and enhances carbon sequestration. New methods have been elaborated to the sustainable regional water management, irrigation, water regulation, defence against internal water, and soil protection established. Water management contributes to the balance of water quantity on one side, but also to mitigating the climate change on the other. -
The development of the scientific bases of horticulture and the history of horticultural innovation in the Northern Great Plain region and in Debrecen
17-20Views:90It can be told about the second half of the XXth century that, apart from preferring the large-scale growing of field plants and the largescale
livestock farming, corresponding to the central political will of the communist era, the significance and innovation output of
horticultural education in Debrecen was rather of follow-up trait, of secondary importance. The Tobacco Research Institute continued the
research work, and then even this activity was stopped. According to a survey finished in 1997, the mentioned institute had no invention,
granted patent, protection for registered model or any application for patent in progress at the Hungarian Patent Office. Until this time, invention activity at the University of Agricultural Sciences was of medium standard. In the National Patent Office, seven patent applications related to agricultural production and nine patent applications for other fields submitted under the inventors’ names were recorded. In the same period, the Cereal Research Institute (Szeged) led the absolute innovation list of Hungarian agricultural R+D institutions and university education institutes by submitting 164 own patent applications. Both in domestic and international terms, the horticultural innovation conducted at the University of Agricultural Sciences, despite the individual research results and achievements deserving recognition, without appropriate background – remained unnoticed. Let us put it this way: for the past decades, the light of the Debrecen Flower Carnival has not been thrown on the horticultural teachers and researchers of Debrecen. -
Evaluation of blue and red corn landraces
239-243Views:135Corn breeding can be successful only on a broad base of genetic material. The expansion of breeding aims includes the research of germplasm materials. In our experiments, we examined 11 blue, purple and red exotic corn varieties on two locations in Hungary. We conducted a complex study to obtain more information. We studied several morphological and phenological features and determined the most important qualitative parameters (protein, fat, ash). We applied the Tassel Area Index (TAI) under Hungarian conditions and compared it with the pollen producing ability of different genotypes. Results show that there are great opportunities in exotic corn varieties. Their quality exceeds that of the yellow ones in many cases. There are significant differences in yield and nutritional parameters. The favorable nutritional composition is not coupled with great productivity. Based on their flowering time and their agronomical features, they can be cultivated under Hungarian conditions as well. They match the new breeding aims, so they can be used as functional food or energy plants. With their high pollen producing ability and TAI, they can be utilized as markers in future pollen research.

Let's talk about 'One fungus One name'. Changes in the fungal taxonomy
11-14Views:223Mycologists have recorded a few hundred thousand Latin names for fungi and these are thought to refer to 70 000 or so separate species. The use of molecular techniques in fungal taxonomy and systematics in the last 25 years has provided massive amounts of information to clarify phylogenetic relationships, encouraged grant support, and complicated the jobs of classically-trained mycologists. Taxonomists have a reputation for being traditionalists, but the community has recently embraced the modernization of the nomenclatural rules by discarding the requirement for Latin descriptions, endorsing electronic publication, and ending the dual system of nomenclature, viz. teleomorph and anamorph names, which used parallel for the sexual and asexual phases of pleomorphic species. A group of taxonomists accepted ’The Amsterdam Declaration on Fungal Nomenclature’ and its basic principle the ’One fungus – one name’ has been incorporated in the Code of Nomenclature (’Melbourne Code’) in 2011. The next, and more difficult step will be to develop community standards for sequence-based classification. As the’One fungus – One name’ theory is a brand-new issue for the Hungarian plant doctors and practical specialists, it seems reasonable to review this to promote conversations between generations in Hungarian language.

Effect of anthocyanin-rich Hungarian tart cherry extract on blood antioxidant status in C57BL/6J mice
335-341Views:220In this study male C57BL/6J (B6) mice were used to determine the possible effects of our Hungarian tart cherry extract in a chronic obesity mouse model on antioxidant capacity.
The control group received standard mouse chow, the high fat control group was switched to high fat diet and tap water supplemented with 5% sucrose. The high fat+anthocyanin group received the high fat and sucrose diet, but dissolved in the drinking water they received anthocyanin-rich tart cherry extract. After six weeks, the antioxidant capacity and SOD activity were measured. Antioxidant capacity was decreased with a significant elevation of SOD activity. The tart cherry extract made a significant enhancement in antioxidant capacity and SOD activity. Our results show that chronic anthocyanin intake has a potential to enhance redox status associated with obesity.

Review of the biology of plant psyllid (Cacopsylla pruni, Scopoli 1763), and its role in the spreading of European stone fruit yellows, ESFY-phytoplasma with Hungarian data
25-33Views:360The European stone fruit yellows (ESFY) phytoplasma disease caused by pathogen ’Ca. Phytoplasma prunorum’ induces serious damages in cherry, sour cherry, peach, and apricot orchards mostly in Europe. Its known vector is the plum psyllid (Cacopsylla pruni). Many articles report on the biology (morphology, taxonomy, life cycle etc.) and the method of transmission of the pathogen by the vector, and the possibilities of their control. This paper reviews our knowledge about the vector, and summarises the results of an inland research carried out in a northeastern Hungarian apricot orchards. Our goal was to show some important data for the farmers or anyone who is interested in this disease and its vector. And give some known method that we can protect our orchards against them to prevent the appearance of the disease. As the psyllid that became infected with the pathogen can hold its infectionous capacity during their lifetime, it is very important to have enough knowledge about their lifecycle, that we can determine the right time and method to control them. We also have to know how to identify them; therefore, this paper lists several important data which can be helpful. The most important keys of identification are their wing color, which dark borwn in the apex and brown is in the remaining part of the forewing. The length of the antennae is also an important factor, since other genuse’s species have longer antennae than twice the width of the head. C. pruni has as long antennae as twice the width of the head. They return to Prunus species in early spring and we have to protect our orhards in this period against them. We have to use preparations with a knock down effect on them to prevent the inoculation of the pathogen into the trees in our orchards.

Data on the Orthoptera fauna of characteristic agricultural landscape in the Carpathian Lowland
25-34Views:187Orthoptera fauna and assemblages of natural and semi-natural grasslands of the Hungarian Lowland are well-known, however, little is known about assemblages living in agricultural and anthropogenic habitats such as arable lands, roadsides, hedges, and riverbanks. Due to climate change, intensification of agriculture, and change of habitat use, these habitat types become increasingly important.
To collect data on these mainly unknown habitat types, a three-year study was carried out on the Orthoptera fauna and assemblages of the firth region of the Tisza and Sajó rivers. This area was mainly unknown, and our research contributes to increasing knowledge and provides a base for further investigations.
In the 40 sampling sites of the studied region, an occurrence of 30 Orthoptera species was recorded based on 2241 sampled individuals. In this study, we provide 540 new distribution data records of orthopterans that means an almost eightfold increase of the known data. Orthoptera assemblages of different agricultural habitat types showed significant differences considering both species richness and composition. Data suggested that non-cultivated habitat patches of dirt-roads, roadsides and stubble fields and even extensively used pastures, hayfields and alfalfa, red clover, and even wheat fields can preserve relatively species-rich Orthoptera assemblages. Contrary weedy sites of these cultivars and intensively used arable lands (maize, sunflower and rape fields) showed extremely low species diversity.

Preservation of Biological Diversity of Domestic Animals in Hungary
18-29Views:115Since the 1992 Rio de Janeiro UNO Congress domestic animals belong also officially to the genetic diversity of the world. Non commercial domestic animal breeds should be maintained for many cultural and technical reasons. Conservation and preservation of living beings is nowadays in the programme of many regional, national and international organizations.
The preservation of domestic animals is possible in situ (at the original place and conditions) and ex situ (by cryogenic methods).
There are three era in the history of preservation of domestic animals: the epoch of spontaneous maintenance, the period of sporadic national activities and the era of international programme.
Some of the questions to be solved by scientific research: the principles of selection of the candidate populations for maintenance, the different degrees of endangeredness, the necessary population size to be subsidized, the problem of inbreeding, the best mating systems etc.
In Hungary the maintenance of endangered domestic animal breeds is based upon the low.
The following breeds are on the list of protected breeds:
− the Hungarian Grey cattle,
− the Lipizzan, Shagya, Nonius, Gidran, Furioso,Kisbér Halfbred, Murinsulaner and Hucul horses,
− the Racka, Tsigai and Cikta sheep,
− the Mangalitsa pig,
− the Hungarian yellow, white, speckled and the Transsylvanian naked necked hen,
− the Bronze Turkey,
− the Frizzle Feathered goose.
Hopefully in the near future the breeders of traditional domestic animal breeds will find the possible niches for their special products. -
Economics of broiler fattening in Hungary
171-180Views:95The purpose of this study is to present economic circumstances of Hungarian broiler sector based on secondary data after brief introduction of international and home situations. Then it analyzes costs, revenues and profit relationships of producers, which has competitive efficiency indicators and high standard production based on a model created on the basis of primary data.
The paper confirms the Hungarian poultry sector international competitiveness falling. One important reason of this situation is the low profitability in the sector, which is typical of both farms produce under worse efficiency indicators and high standard producers. Beside lack of technological standards and efficiency, adverse trend of output and input price – mainly feed price – impact low profitability.
Realization of technological developments and improvements according to international tendency, which affect directly or indirectly the efficiency and costs of broiler fattening are determining in point of realizable profit -
Analysis of changes in resources and outputs of companies and partnerships in Hungarian agriculture
65-68Views:115The aim of the study was to examine the achievement of Hungarian agricultural companies and partnerships, particularly agricultural co-operatives based on the aggregated database of National Tax and Customs Administration (NAV)1. From the methodological aspect, descriptive statistical methods and time series analysis were used. One of the most important conclusions is that the socio-economic weight of the agricultural co-operatives was strongly decreased in the period after the EU accession. The other important statement is that apart from the general examination of economic actors on aggregated level the comparative analysis of the single organizations forms would be needed. In the case of co-operatives, separated examination of the former type producer co-operatives and the so-called new type ones (e.g. marketing co-operatives etc.) would be necessary.

Possibilities of Farm Management Decision Support
287-292Views:49Computer science has a major role in the decision-making process of farmers. In this process IT can be applied to virtually all phase: from infromation gathering to information processing. I am examining the position of informatics in the decision-making process. IT can be used in every single phases of the decision-making process. In my essay the useage of Internet and the possibilities it can provide play a significant role.After a brief description of the IT position of Hungarian agriculture I am introducing some programs, which can be used in the management’s decision-supporting system. Besides the Hungarian experiences the West European surveys also comfirm the application of Information Technology.

Efficiency evaluation of service marketing at a Hungarian telecommunication company
41-47Views:144The article discusses the marketing effectivity of a communication service at a Hungarian telecommunication company. The main target is to establish economic effectivity of the enchanced promotion of the service. The basic metholodogy was the comparison of a new marketing plan and real figures of the planned period. The results of 2005 and 2006 show a very
positive financial effectivity of the surplus communication. Based on the results a further promotion is suggested. -
The production and financial achievement of the agricultural co-operatives in 2002-2007
21-28Views:112The aim of the study was the examination of the achievement of the Hungarian agricultural enterprises – special regard to the agricultural co-operatives – based on the aggregated database of Hungarian Tax and Financial Control Administration (APEH), from the database of the Research Institute of Agricultural Economics. From the methodological aspect plain statistical devices were used, indicators for corporate analyses were
calculated and analyzed for the time series. One important conclusion is that the socio-economic weight of the agricultural co-operatives was strongly decreased in the period after the EU accession. The other important statement is that over the general examination of economic actors on an aggregated level the comparative analysis of the single enterprises forms would be needed. In the case of the co-operatives the separated examination of the former type producer co-operatives and the new type co-operatives would be necessary -
Impact of precision irrigation on the unit income of maize production
157-162Views:80The study of the economic/economic impact of precision farming should be a priority area in digital agriculture, as the results, profitability, and efficiency indicators can have a significant decision-support effect on the development of both the agronomic and the technical regions of individual farms both in the longer and shorter term. Individual firms, companies, farmers, and family farms quantify the effectiveness of their farming processes. The modern age offers the possibility of digitally recording all the elements of farming technology, making it possible to analyse the cost-effectiveness of a farm more effectively and, in some cases, to carry out more detailed analyses. Nevertheless, the number of farms demonstrating their profitability with such precise economic calculations is still minimal.
Our analyses were conducted on a 56,02 ha field of Balogh Farm-Tépe Ltd. The agricultural operations carried out were fully documented so that the inputs (seeds, fertilisers, pesticides, crop enhancers) were recorded in coordinates and kind, as well as the specific yields, grain moisture data, irrigation norms, and irrigation rotations. At the same time, the company's owner provided the data's monetary value. The main econometric indicators (yield, production value, cost of production, income, cost price) related to the evaluation of the enterprise management were evaluated along with the spatial data in the irrigated and non-irrigated tables. Our calculations show that a given year's climatic and market characteristics fundamentally determine the cost and income relations of a plot of land (and thus of an entire farm). In addition to additional inputs, introducing some elements of precision farming and intensification and increasing yields improves yield security and allows for excellent yield stability.

Utilization of Okra (Abelmoschus esculentus L. Moench.)
122-125Views:132Okra is warm season crop native to Africa. Presently it is widely grown in the northeastern parts of Brazilia, both northen, and western parts of Africa, southeast Asia, and in the eastern parts of the Mediterraneum. In Hungary it is a rarity. It’s adaptation to Hungary began about 40 years ago.The optimal sowing time under Hungarian climatic conditions is middle of May. The harvests is started – depending on the weather – first, by the middle of July, and picking continues until the first of September.
According to our results, seed soaking, sowing under a perforated foil sheet-covered trench (2 weeks earlier the normal sowing time), and 55-65 g thousand weight seeds are favourable.
The harvest period under Hungarian circumstances is appr. one and half months. -
The effect of immigration on some population genetic parameters of the Hungarian Hucul population
91-96Views:151Population genetic indicators of the Hungarian Hucul population were calculated taking also into account the effect of imported horses.The birth year of the examined 3002 individuals ranged between 1871–2015. The last year involved in the examination was 2015, when the research was conducted on the stock under stud book control. The calculations on the population were made using the statistic indicators in the Endog programme, with and without the imported Polish horses. Figures were depicted using R software. Number of offspring of the Polish individuals was presented in tables; the distribution of the offspring per stud and per mare family, as well as the Nei’s genetic distance,were presented graphically.

Baking quality of winter wheat (Triticum aestivum L.) in the long-term experiments on chernozem soil
152-156Views:100Agriculture has traditionally an important role in Hungarian economy and rural development. About 75 % of Hungary’s total territory
is under agricultural land use. Because of ecological conditions and production traditions cereals (wheat, maize etc) have the greatest
importance in Hungarian crop production. In the 1980’s the country-average yields of wheat were about 5,0-5,5 t ha-1 („industrial-like”
crop production-model). In the 1990’s the yields of wheat dropped to 4,0 t ha-1 because of low input-using and wide application of the issues
of environmental protection and sustainability. Winter wheat production for quality has a decisive role in certain regions of Hungary
(eastern and middle-parts).
The quality of wheat is complex and different. Three major growing factor groups determine the quality of winter wheat: genotype,
agroecological conditions and agrotechnical factors. In wheat production for quality the selection of the variety is the most important
element. Our long-term experiments proved that the quality traits of a variety means the highest (maximum) limit of quality which could not
be exceeded in fact. During the vegetation period of wheat the different ecological and agrotechnical factors could help or on the contrary
could demage the quality parameters of wheat.
The agrotechnical factors determining the baking quality of wheat can be divided into two groups: the first group means the factors with
direct effects on quality (fertilization, irrigation, harvest); the second group contains the elements with indirect effects on quality (crop
rotation, tillage, planting, crop protection).
Appropriate fertilization could help to manifest the maximum of quality parameters of a wheat genotype and could reduce the qualityfluctuation
in unfavourable ecological and agrotechnical conditions.
