The potential of biological control on invasive weed species
73-75Views:97Sorghum halepense is one of the invasive species in Europe. This study was made to identify the morphology of fungi on invasive weed species samples on the roots of Sorghum halepense. The samples were collected in the region of Debrecen. The experiment was conducted under laboratory conditions to determine the microscopic form of fungi. The samples were put on PDA and for identification of fungi is based on the morphological characteristics of the features and colonies of conidia that were developed in Petri dishes.
The examination of the culture revealed that the fungus from the root of Sorghum halepense was Aspergillus niger. Pathogenicity and the relationship between the fungus and Sorghum halepense are still uncertain so in the future pathogenicity tests and re-isolations from plants are very important steps.

The effect of the plant density for the yield of the maize hybrids
50-61Views:103In order to enchance the yield stability of maize, the effect of plant density on yields was studied on a typical meadow soil in Hajdúböszörmény between 2002-2004. In the plant density experiment, we used the method of Béla Győrffy. The plant densities applied therefore 20 to 100 thousand plants/ha by ten thousand scale. The application of fertilizer rates for the maize hibrids in every year were N: 110 P: 90 K: 120 kg/ha. We used a manual soiling-gun in the experiment. In every year we used plant protection techniques against monocotyledonous and dicotyledonous weeds. The harvest was done by hand. The facts were read by variancie analysis and linear regression analysis. The moisture and the temperatures were extreme in 2002, 2003, 2004. We have to mention defficiery of moisture in 2003 which is shown that the hot days number increased. After evaluating our findings we can conclude that most hybrids showed a significant correlation between increased plant density and the volume of yields. On the basis of the experiments we divided the hybrids into four groups: the first group included the hybrids suitable for increased plant density with a wide range of optimal density values; the second group included hybrids, which did not require high plant density, were capable of good individual performance and tended to grow several ears; the third group included flexible corn types, which grew longer ears in favourable years, thus yielded more; and the fourth group included the hybrids, which were sensitive to increased plant density and which showed a narrow range of optimal density values. Finally, plant density determines the yield; we have to consider optimal plant density intervals as well as optimal plant density, and we also have to place a high emphasis on the use of hybrid-specific technologies.

Using the principles of precision animal husbandry in fishbreeding
283-287Views:214Aquaculture species such as fish, crayfish, molluscs and plats are a wide range of products, with continuously growing demand worldwide. The reasons for this is that they are cheap and easy-toraise protein sources, thus having significance in food supply especially in developing countries in tropic regions, moreover, the premium category foodstuffs in developed high income countries are also belonging to this category. World annual total production of 164 million tons (2009) are made up of two sources: 1) marine and inland fisheries landings that are stagnating for several years and 2) aquaculture which is growing dynamically with annual 6% rate between 2000–2009. The latter is accounting for nearly 45% of the total supply due to the depleting marine stocks caused by overfishing. Aquaculture is growing continuously also because the production is safe and can
be planned well.
Intensive fish production systems are the representatives of precision animal production, several types exist and widespread worldwide. The modern computerized temperate water recirculation plants with several thousand m3 capacity are widespread also in Europe because they make it possible to produce even the most valuable species whole year round. A key issue in the technical/feeding outlay is to meet the demands of the cultured species the best and the operation of the system is to be safe and cost-effective. One condition for this is intensification: enable to produce more product per unit resource input or effort. The facilities need significant amount of energy, thus renewable energy sources are to be favoured for which Hungary has comparative advantages. -
Study of plant physiological parameters in winter oilseed rape (Brassica napus var. napus f. biennis L.) production on chernozem soil
111-115Views:209We made plant physiology examinations in Arkaso winter oilseed rape hybrid substance: relative chlorophyll content (SPAD) and leaf area index (LAI) measurements. The experiment was set in University of Debrecen Agricultural Sciences Center at Látóképi Experimental Station in four replications, in two different sowing times (I. sowing date on 08/22/2014 and II. sowing date on 09/09/2014 sowing againhappened because of the incomplete germination in the second subtance 01/10/2014) Three different plant density 200, 350 and 500 thousand ha-1, under the same nutrient supply, 45 cm row spacing. The experiment was green crop of winter wheat. The relative chlorophyll content (SPAD) and leaf area index (LAI) measurements were made in seven different times. We measured the maximum value of chlorophyll content in the first sowing time at 500, and the second sowing time at 350 thousand ha-1 plant density. The measurement results proved that there was a linear relationship between the number of plants and the LAI. The maximum leaf area index values we measured in both the sowing time at 500 thousand ha-1 reached.

Phenometric studies on stalk juice and sugar contents of silo sorghum types
41-49Views:85Bioenergies (among them e.g. bioalcohol) can be solutions for the replacement of fossil fuels. For its production, plants with high sugar or starch content can be used. Juice pressed from the stalk of sugar sorghum has high sugar content (14-17%) that makes it suitable for bioethanol production. During our experiment, we examined 53 restorer male lines; among them 22 were silo type sugar sorghum. We studied the following traits: plant height, breeding time, level of foliation, stalk diameter, characteristics of stalk medulla, juice content of stalk, sugar content of stalk juice. According to examined characteristics, we selected six restorer male lines for studies in the forthcoming years: RL 1, RL 2, RL 3, RL 4, RL 5, RL 9, RL 12, RL 15, RL 18. Their stalk medullas were wet, stalk diameters were medium-thick, sugar contents of juices varied between 17 and 24% at the end of milk mature. Harvest was made in September, they can be classified into early maturation group. Male sterile female lines were the following: SL 1, SL 2, SL 3, SL 4, SL 5. The maintainer male lines were: CL 1, CL 2, CL 3, CL 4, CL 5. In Hungary, there are only a few male sterile female
lines, so we will use these lines for hybrid production during the next years. -
Penicillium chrysogenum antifungal protein (PAF) production in transgenic tobacco (Nicotiana tabacum) plant
77-82Views:108Under the „Molecular farming” research program (product vaccines and substances for medical use with gene manipulated plant) in 2007 in UD Centre for Agricultural Sciences and Engineering Faculty of Agricultural Science Institute of Horticulture Department of Plant Biotechnology experiments were launched to transform tobacco plant by PAF antifungal protein. Our aim was to learn the transformation technics. We chose the
Nicotiana tabacum and PAF as model systems.
Our work was to express several different paf constructions in plants with nuclear and plastid transformation too. After that we confirmed the presence of paf gene in the level of DNA and RNA. -
Plant protection praxis on Hévíz Nature Conservation Area (Lake Balaton District, Hungary)
81-83Views:162The nature conservation park, which belongs to the Spa and St. Andrew Hospital for Rheumatics of Hévíz, is 60 ha in size. The famous Lake of Hévíz, the two overfalls and the main buildings of the hospital are located in the middle of the park. They are surrounded by protective forests, parks and gravel esplanades. During the past few decades, the population of neophyton plants and invasive insects have increased considerably. These mean serious challanges to develop efficient control methods. Special care must be taken of environmental and plant protection regulations. Keeping plant protective regulations are especially strict around natural and spa waters.

Allelopathic Effect of Italian Cocklebur on Sugar Beet
74-77Views:104Cockleburs are noxious weeds in Hungary, where they are widespread in row crops, especially in maize, sunflower and sugarbeet. A low density population of these weeds may be harmful because of their large competitive ability, fast growth in early phenological stages, allelopathy, and persistant sprouting.
Allelopathy of Xanthium italicum Mor. was examined during the growing season in 2004. Root and shoot samples were collected at 4 or 5 leaves stage (in the end of May and in the beginning of June) and before flowering (in the beginning of July) before and after rain. Extracts were made in tap water. The test plant was Beta vulgaris L.; its germination, root and shoot growth were evaluated at the 6th and 10th days after treatment.
Most of extracts inhibited the germination of sugar beet. In these experiments the phenological stage of the donor plant determined slightly the effectiveness of the extracts on sugar beet. Generally, significant differences existed between treatments only in cases of concentrated extracts.
Rainfall can modify the inhibitory effect of extracts (especially shoot extracts). Shoot extracts of young plants inhibited stronger germination and growth after rain than before rain. Density of cockleburs influenced the effect of extracts, as well. Generally, differences between the efficacy of extracts was larger after rain.
The results supported the hypothesis that the phenological stage and some environmental factors can modify allelopathy of cockleburs. -
Physiological examination on cadmium sensitvity of some maize and sunflower varieties
169-173Views:108Cadmium is one of the most dangerous heavy metals, which may cause serious problems in certain physiological processes of living organisms even in small amounts. In our work we analysed how cadmium affects some physiological parameters of different maize and sunflower hybrids. The chlorophyll contents and the morphological changes of the root were examined. We received different results in terms of the cadmium tolerance of these two plants.

Examination of the chlorophyll content of maize hybrids of different maturity groups at different N fertiliser doses
159-162Views:128Nitrogen fertilisation is a critical point of maize production. Five hybrids of different maturity dates were examined in a field experiment, three treatments (different application dates) and three basic fertiliser doses (0, 60, 120 kg ha-1 N) were used. At the 6-leaf-stage of maize, each fertilisation level of the 2nd and 3rd treatment was given 30 kg N ha-1 fertiliser active ingredient in addition to the basic fertiliser doses with the exception of the control plots and further 30 kg N ha-1 fertiliser was applied at the 12-leaf-stage. The final fertiliser doses were 0, 90 and 150 kg N ha-1 in the second treatment and 0, 120 and 180 kg N ha-1 in the 3rd treatment. The whole amount of the basic fertiliser (ammonium nitrate) was applied in the spring, one month before sowing.
The relative chlorophyll content of the maize leaves was measured, with a Minolta SPAD-502 measurement device. The measurements were carried out at the 6-leaf growth stage (V6) of maize on the youngest fully developed leaf of the 6th, 7th and 8th plants from the second row of each plot.
There were significant differences in the SPAD-readings measured at the V6 phenophase of maize between the hybrids (p<0.001) and the fertiliser treatments (p<0.05). The regression analysis did not show any correlation between the SPAD-values and fertilisation.
The highest significant SPAD-reading and yield were obtained by applying 120 kg ha-1 N. As a result of the regression analysis performed on yield, it can be concluded that the correlation between fertilisation and yield in the 1st and 2nd treatment was moderately close (r=0.439, r=0.480) and it was close in the 3rd treatment (r=0.513). The correlation between the SPAD-readings and yield was the closes in the 2nd treatment (r=0.639), while the SPAD-value had a 40.9% influence on yield (p<0.001).

The effect of sulphur and nitrogen supply on the growth and nutrient content of spring wheat (Triticum aestivum L.)
65-70Views:228Sulphur is an essential element for plants. Decreasing sulphur deposition from the air, and the use of more concentrated phosphate fertilizers, which contain no sulphur, has led to reports of sulphur deficiencies for wheat. Sulphur deficiency significantly affects yield and also the quality of wheat. The pot experiment was set up on calcareous chernozem soil at Látókép, Hungary, test plant was spring wheat (Triticum aestivum L). Seven treatments were used where nitrogen and sulphur were supplied as soil fertilizers in increasing rates (NS1, NS2, NS3) and in foliar fertilizer as well (NS1+fol., NS2+fol., NS3+fol.). Plant aboveground biomass production was determined in samples taken in the stages of development BBCH 29-30, 51-59, 61-69, 89. The nitrogen and sulphur content of straw and grain were measured. N/S ratios of grain and straw were calculated. The weights of grain were ranging between 8.6–16.1 g/pot. NS2 and NS2+fol. treatments produced the highest values. Foliar fertilizer had no further effect on grain. Analysing the values of the straw, it was observed that tendencies were similar to values of grain. The NS2 treatment produced the highest weight of straw and the NS3 rate already decreased that amount. The obtained results show the unfavourable effect of excessively high rate applied in NS3 treatment. The supplementary foliar fertilizer had no significant influence on the weight of straw. Both N and S-uptake of plant was very intensive at the stem elongation stage, then the N and S-content of plant continuously decreased in time in all treatments. The N-content of grain ranged between 2.215–2.838%.The N-content of grain slightly increased with increasing of nitrogen doses. In the higher doses (NS2, NS3) foliar fertilization slightly increased the nitrogen content of grain, although this effect was not statistically proved. The N-content of straw varied from 0.361 to 0.605%. The growing dose of soil fertilizer also considerably increased the nitrogen content of straw. Foliar fertilization further increased the nitrogen content of straw. The S-content of grain ranged between 0.174–0.266%. The lowest fertilizer dose (NS1) significantly increased the sulphur content of grain. The further increasing fertilizer doses (NS2, NS3) did not cause additional enhance in sulphur content of grain.The foliar fertilizer also did not change the sulphur value of plant. The increasing amount of soil fertilizer and the supplementary foliar fertilizer had no effect on the sulphur content of straw. The treatments influenced the N/S ratios of grain and straw. On the basis of experimental results it can be concluded that the examined nitrogen and sulphur containing soil fertilizer had positive effect on the growth and yield of spring wheat grown on the calcareous chernozem soil. The soil fertilizer application enhanced the grain nitrogen and sulphur content. The highest rate of fertilizer (600 kg ha-1) proved to have decreasing effect on the yield. The sulphur and nitrogen containing foliar fertilizer did not have significant effect on the yield parameters but slightly increased the nitrogen content of plant. -
Alternative Income Sources in the Agriculture of Settlements Along the Hortobágy
234-239Views:57Agriculture has played a dominant role among the income sources of population living along the Hortobágy just like in any other rural areas. I represent the situations of settlements along the Hortobágy by studying four of them, such as Balmazújváros, Hortobágy, Tiszacsege and Egyek. Big companies having worked in the examined settlements had significance in ensuring local working facilities, and restraining people from leaving. Acts dating back to the beginning of the 1990’ies, privatisation, transformation of the state farm and co-operatives have decreased the rate of employment in agriculture. Alternative income sources relating to agriculture, such as bio-farming by alternative plants, herb production and rural tourism will determine the future of agriculture in this area due to the closeness of the Hortobágy National Park, the unique but unfavourable natural conditions for agricultural production, financial aids by the National Agricultural Environmental Programme and the imminent EU-membership. In this way supporting these activities may ensure the livelihood of ex-agricultural workers and alternative income for those working in agriculture.
I am going to deal with two issues in this article:
• with the change of the role of agriculture in the examined settlements,
• with economic analyses of alternative income sources by a model of a family farm. -
Examination of two artichoke cultivars under single year Hungarian climate conditions
112-115Views:80Based on the results of a previous experiment, we concluded that by choosing a suitable cultivar, it is possible to produce artichoke in a one-year cultivation system in Hungarian weather circumstances. The objective of the present experiment was to investigate the performance of two Californian artichoke cultivars (Green Globe, Imperial Star) under the local conditions. Experiments were conducted in 2002 and 2003, by using four
different sowing and two different planting dates (03.01. and 03.20. – planting 05.07.; 04.24. and 05.06. – planting 06.12.). For both cultivars, 100% of the plants initiated buds. In most of the cases, Imperial Star produced higher total and marketable yields than Green Globe did, while it formed bigger and more uniform buds. Our opinion is that the main reason for this result was that Imperial Star tolerated the dry and warm Hungarian summer much better. Irrespective of the variety by earlier sowing dates higher total yield was achieved. Based on our results, we found that under Hungarian circumstances, both cultivars could produce acceptable total yields. However, the weather circumstances of the given year influenced bud quality, and thus marketable yield, to a great extent. -
Exogenous salicylic acid treatments enhance tolerance to salinity of wheat (Triticum aestivum) plantlets
34-38Views:128Salt stress, an abiotic stress, determines modifications of some biochemical indicators, like, antioxidant enzymes, proline (amino acid
accumulate in higher plants under salinity stress) content, and some physiological processes including: plant growth and development. In
this paper we studied the influence of exogenous treatment of wheat seeds, with 0.1 mM salicylic acid (SA) solution, in the plant response to
salt stress. The treatment was applied by presoaking the seeds in the treatment solution for 12 hours before germination. The results showed
that exogenous 0.1 mM SA solution, administrated to the wheat cariopses significantly ameliorated the negative effect of salt stress in first
week of germination in laboratory conditions. -
Investigation of host-specificity of phytopathogenic fungi isolated from woody plants
155-160Views:160Host-specificity is an important characteristic of fungal pathogens. Changing climate could create more appropriate environmental conditions for phytopathogens, thus formerly host-specify fungi could be able to colonize new hosts. Noxious plant pathogen fungi, which can infect several plant species are well-known worldwide. These genera may expand their range of hosts because of the appearance in new geographic areas due to climate change. This new exposure can result in serious problems in agriculture because of the lack of immunity. The susceptibility of apple tree was studied through testing pathogenicity in vitro with species isolated from walnut twigs and nuts, and identified by ITS sequences. Three of four tested species, Botryosphaeria dothidea, Diaporthe eres and Diplodia seriata colonized and necrotized the infected apple branches, while Juglanconis juglandina was not able to infect the twigs. Members of Botryosphaeriaceae were the most virulent, causing the largest lesions in the fastest way. This experiment draws attention to the threat of new host-pathogen connections, which can arise because of the favourable weather conditions and can spread between neighbouring cultures.

Relation of availability and barley uptake of some potentially toxic elements
7-10Views:77A small-plot microelement load field trial was set up on brown forest clay soil with eight elements (Al, As, Cd, Cr, Cu, Hg, Pb, Zn), on 3 levels each (0/30, 90, 270 kg element ha-1). The soil was treated with soluble salts of elements once at initiation (1994). In the seventh year of the experiment (2001) winter barley was the test plant. The total element content was determined in plant samples (shoot, straw, grain) after microwave digestion using cc.HNO3+cc.H2O2. The element composition of the prepared samples was determined using ICP-MS technique. In the experiment toxic effects of treatments and yield loss could not be observed. Zn and As contents in barely shoots were only moderately increased by increasing microelement loads. Effects of Cr, Cu, Hg, Pb and Al treatments could not be observed. On the other hand, Cd accumulation was significant in the shoot. Cd content was also increased both in straw and grain. Results of this experiment prove that Cd remains mobile in the soil-plant system for a long time. Its accumulation can be observed both in vegetative and reproductive parts of plants without toxic symptoms and yield loss.

Possibilities for Growing Fennel in Hungary
119-121Views:68Fennel appers to be cupable of enlarging our vegetable sortiments in Hungary. Ecological conditions favour production. For cultivation, 12,5 plants/m2 are recommended. Fennel requires 250-300 mm water over a 110 day growing period. No considerable pests have been found yet. 1-3 kg/m2 tubers can be harvested. Marketable tubers weigh 200-300 g. Smaller tubers can be dried, pickled or deep frozen.

Usage of different remote sensing data in land use and vegetation monitoring
7-12Views:144The use of remote sensing in forest management and agriculture is becoming more prominent. The rapid development of technology allowed the emergence of database suitable for precision application in addition to the previously used low-resolution and low data content images. The high resolution, hyperspectral images are not only suitable for separating the different land use categories and vegetation types but also for examining the soil characteristics and biophysical features of plants (Blackburn and Steel, 1999; Condit, 1970). We processed a multispectral satellite image (Landsat 7 ETM+) and a hypespectral areal image (DAIS 7915) about a farm on the plains and evaluated the different image classification methods. During our examinations, we examined the geometrical and radiometrical characteristics of images first, then assigning the training areas, we determined the spectral characteristics of land use categories. We performed a multispectral analysis for checking land use, where we compared controlled and uncontrolled classification systems to check their reliability. We used areal and spectral reductions to make the classifications more accurate and to reduce the length of calculations.

Comparative study of honeys and herbhoneys quality paramertes
117-120Views:202Honey is one of the oldest known and consumed food. Besides the pleasant sweet taste it has been consumed because of the favorable health benefits. In addition to large number of honey plants there are many popular herbals which cannot serve as a nectar source. The herbhoney has been developed that consumers can joy the pleasant properties of herbals and honeys positive impact on the same product. In our research we compare the quality parameters of honeys and herbhoneys to each other and with the relevant regulation.

Changing of some parameters of the soil-plant system as an effect of different composts
262-266Views:127Composting is an alternative way for practicing site-specific and environmental friendly plant nutrient supply. Our aim was to study the effect of different composts on plant and soil system.
Pot experiment with acidic sandy soil blended with three composts in five (0%, 5%, 10%, 25% and 50%) proportion was set up. Our experimental plant was perennial ryegrass (Lolium perenne L.). After the harvest of ryegrass we measured the fresh and dry weight of harvested plants, the P-, K-, Mg-contents, and the pH of soils.
The three composts had different effect on dry weight production and on nutrient-supply of soil. We established that one of the compost had significantly larger effect on the dry weight of ryegrass compared to the others. In this study we proved that favourable compost/soil proportion is different in the case of different composts. -
Regional interactions of bioenergy utilization
159-162Views:68The backwardness of the rural areas compared to the cities poses a problem all over Europe. In Hungary, a relatively small size of the population lives in the capital, more than 80% of Hungarians live in rural cities or villages. The tension between the countryside and the cities is rather intensified and the symbiotic correlation would need to be restored. Many people migrate from the countryside, especially young adults, as they have no opportunities to find a job in their hometowns. This phenomenon poses big risks because getting a job is usually difficult everywhere and because fitting into a new environment always involves a lot of difficulties.
Non-renewable energies are restricted and they will not be accessible after reaching a certain limit. People’s everyday activities and the functioning of the economy presuppose the availability of the necessary amount of energy. In the future, a solution that provides the longterm stability of energy for the world will become increasingly necessary. There is a huge potential in bioenergy, more specifically in biomass. The building of biomass plants and putting them into operation creates jobs in the rural spatial environments: a locally available resource that can help in creating the energy safety of the country and the reduction of the dependence on import. The production of energy crops or the crops whose purpose of use is energy could help in strengthening the multifunctional character of agriculture and it can represent a source of income for those living off agriculture under the current uncertain conditions.

Changes in toxic elements content of soil after sewage sludge treatment in energy willow plantation
7-10Views:128The primary purpose of our experiment was the solution of municipal excess sludge treatment by a renewable energy resource used willow (Salix viminalis L.) plantation. Tests were carried out to state whether the applied sewage sludge has caused any accumulation of the toxic elements in the studied soil layers, and - based on the results –to see whether the plantation is suitable for the treatment of municipal sewage sludge.
The excess sludge (sludge before dewatering) is beneficial for the willow, because it contains a 3–5% dry matter and therefore, a lot of water, too. This high water content ensures the high water amount needed for the intensive growth of the willow. On the other hand, the wastewater treatment plant can save the dewatering cost which corresponds to about 30% of the water treatment process costs. The amounts of the sprinkled sewage sludge were calculated on the basis of its total nitrogen content. Treatments were the followings: control, 170 N kg ha-1 year-1 and 250 N kg ha-1 year-1. The mean values of the toxic element concentrations in the sewage sludge did not cross the permitted limits of the land accommodating.The measured toxic element values of the soil were compared to the limits of the 50/2001. (IV.3.) Government Regulation.The sprinkled sewage sludge on the bases of the total N content did not cause accumulation of heavy metals in the soil and the treated plants were also healthy without any signs of toxicity.

Grassland association stock of plants the examination of the regeneration of a construction
185-191Views:67Due to the drastic change in using the nature like grassland association (one-sided overgrazing – one mowing per a year), by the third year of the experiment in every area, where overgrazing stopped, independently on second sowing and nutrient resupply, Borhidi degradation degree decreased. In the areas where overgrazing with large animal density (sheep) continued, degradation degree was 3.4–5.0 by the third year of the experiment, and Hordeum murinum, which causes animal healthy problems, appeared massively.

Does drought stress always negatively affect the yield and quality of soybean in Hungary?
37-40Views:219Globally-fluctuating climate imposed serious abiotic stresses on the agricultural sector, leading to noticeable, and sometimes disastrous, losses in yields and/or quality of crops; however, in certain cases, plants could survive stress with relatively low reductions, and sometimes even with some enhancements as a reaction to changed environment, especially in the case of mild stress. An experiment was conducted in 2017 and 2018 in Debrecen, Hungary to evaluate the mild drought stress influence on the yield and quality of three soybean cultivars. The results showed that both ES Pallador and Pedro cultivars could achieve more yield when subjected to mild drought conditions; however, protein concentration was enhanced in ES Pallador whereas slightly degraded in Pedro under drought. The cultivar Pannonia Kincse followed different trend; both yield and protein concentration were reduced under drought. Oil concentration of the three cultivars did not show significant changes; however, it always followed opposite trend to that of protein concentration. It could be concluded that both ES Pallador and Pedro are recommended to be grown under rain fed conditions in Debrecen, whereas Pannonia Kincse is recommended under irrigation conditions.

Evaluation of Origin and Conformation of Excellent Cows with Long Productive Lives
13-17Views:98In the last few decades a new intensive milking stock has developed as a result of breed-converter crossing in Hungary. Beside this reproduction biology of the population was affected adversely by the keeping-, and feeding technology. Serviceable lifetime has shortened and service period has lenghtened. Whereas profitable milk production needs cows with longer productive life, larger life-time production. In our work we analysed the productivity-, and reputation parameters of the 200 highest lifetime-productivity cows of Hungary. We found that inheritance has not got important role in the serviceable lifetime. Adaptability and good constitution of Holstein-friesian is proved by the fact that cows with large life-time production are reared in large plants, some of them in large stocks, industrial environment. We found during the analysis of reputation parameters that these prominent cows mostly have deeper body, higher dairy form, higher rear udder, smaller foot angle. We found some weak connection between the milk production and the reputation. Loose correlations between useful material content and some linear traits were found.
