Economic Aspects of Bioethanol Production
30-38Views:202Sustainability and multifunctionality look to be crucial points of the future of developed agriculture. Energy utilization of a part of the available biomass perfectly fits in these expectations. Bioethanol production allows for the substitution of the most expensive and most pollutable energy source, gasoline, by agricultural materials. This article contains a complex evaluation of economic characteristics of this method and calculations for the expectable economic effects of a would-be Hungarian bioethanol program. This essay includes the most important technological knowledge, a comparison between bioethanol and the competitive energy sources (gasoline, biodiesel, MTBE) and the most interesting elements of bioethanol programs operating in foreign countries. Introduced are which participants in the bioethanol chain have financial interests and counter-interests under present economic conditions in the spread of bioethanol by the enumerazation of macro- and micro-economic factors. The statements and consequences are based on my own calculatiosn so I am truly interested in any professional opinion.

The significance of local meteorological stations in research planning
87-91Views:418The goal of research planning is to optimize human and material resources while maximizing efficiency. If there are databases that can be used as a substitute for own data collection, effective research can be facilitated by reallocating resources. In the case of environmental studies, the knowledge of the climatic conditions of the study period is known to be a key factor in research planning process.
In the present study, the data of our meteorological station in our research area (known as “Szamárháti Tanya”, Kesznyéten, Hungary) was compared with the measurements of meteorological stations operated by the competent water authority. Stations were taken into the study within a 10 and 20 km radius over a period of 21 months, to determine which provided more relevant data from the area.
During the evaluation of results, the relationship between the local and regional weather stations were determined, and deductions were made from the obtained results to support the decision which of the targeted investigations could be of greater benefit.

The correlation of foreign language proficiency, employment and regional competitiveness in the North Great Plain Region of Hungary
74-82Views:135Employment is one of the basic factors when evaluating a region’s competitiveness. Boosting employment figures will also increase individual income. However, the creation of jobs alone will not solve the problems of unemployment, as labour force with skills matched to labour market demands should also be available. Continuous development of the labour force, adjusted to recent needs in the labour market, can contribute to a region’s competitiveness. Mismatches between education and labour market requirements would be too expensive, especially for backward regions like the North Great Plain Region of Hungary. Foreign language education should also be adapted to the changing economy when selecting target languages and language skills. A workforce equipped with contemporary and needed second language skills can be an element in making a region attractive for investors. Although current trends show signs of improvement, Hungary and especially the North Great Plain Region still does not have much to offer in this respect. The paper examines the reasons for the low level of second language acquisition among Hungarians and the population of the North Great Plain Region and explores the ways foreign language knowledge could promote economic development.

History of origin and development of replacement of plants crop rotations is in world agriculture
53-56Views:331In practice of world agriculture a long ago the known problem of decline of harvests of agricultural cultures at their permanent growing, scientific explanation of this phenomenon became possible only with appearance of natural sciences. At first the declines of harvests bound to the toxic action of root excretions cultures on her repeated sowing, with development of humus theory of feed of plants of diminishing of harvests at the permanent sowing began to explain impoverishment of soil on a humus.
During a few centuries the known farmers development the looks in relation to forming of scientific bases of construction of replacement of plants crop rotations in the world systems of agriculture, set history of their development and improvement. The analysis of influence of possibility of optimal satiation of replacement of plants crop rotations is conducted by agricultural cultures on the level of fertility of soil, water and nourishing modes and their productivity. For the terms of the insufficient moistening a positive action is marked black pair on the improvement of the water mode of soil in crop rotations.
In historiography the problem of introduction and mastering of replacement of plants crop rotations for the decision of scientific and practical tasks of agricultural production is represented in many-sided aspects, worked out and the recommended replacement of plants crop rotations that are base on zonal principle of development of world agriculture that passed the protracted term of test and counted on various specialization of economies. But for today development of scientific and technical progress requires intensification of agricultural production with the use of intensive crop rotations and growing of high-performance cultures.
Hereupon there was a necessity of realization of analysis of the systems of historical value of scientifically-practical knowledge about development and improvement of replacement of plants crop rotations, as it gives an opportunity to work out to recommending a production with the use of the most effective elements of the past on modern agrarian business and allows to forecast them on the future.

Information Technology Supports for Student-Centered Language Education
3-6Views:221With the development of computer-mediated communication, the definition of literacy has gained broader dimensions (Murray, 1991). The ability to use new technologies to access, adapt and make intelligent use of information and knowledge is by now viewed as an additional and essential component of literacy. Today’s interpretation of literacy (often referred to as “multiliteracy”) must incorporate the communication that takes place through a growing variety of text forms associated with information and multimedia technologies.
Since it is fast becoming a basic instrument for building the literacies required for success in academic and workforce environments, used as a tool, information technology needs to become a critical component of student-centered English language education. -
Correlation of pruning time and fruiting part differentiation of sweet cherry cultivars
131-134Views:221There are several extended studies in sweet cherry production in Hungary and all over the world i.e. for creation and maintainence of smaller tree crown and high density orchards. The use of suitable dwarf rootstocks for this fruit species are very limited. On one hand, most of the draf rootstocks do not cause enough growth reduction and on the other hand these rootstocks are get old very quikcly and their fruits become small, and therefore, they not serve the requirements for intensification. In summary, there is a need for those rootstock which are vital, regeneration enhanching and delay ageing. Due to ensuring above features, Prunus mahaleb is still an obvious solution for intesive production. Increasing intensification can be obtained by use of modernisation of technological elements and suitable cultivar choice.
According to this increasement of intensity through application of novel technological elements (timing, manner and severity of pruning) and selection of the proper cultivar is implement able. Important differences are experienced between sweet cherry cultivars in their growth attributes, light demand and dynamics of fall back in regenerative potencial of different aged wood parts. From this point knowledge of the abow detailed is very important in order to maintain rentability of already established plantations. Our work shows the formation of production part in
9-year old plantation with spike spindle and free spindle crown forms depending on pruning timing (winter, summer) and determining of their various effects. -
Isolation and identification of endophytic fungi connected to Grapevine Diseases, from the Tokaj wine region, Hungary
61-66Views:406Grapevine 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.

Evaluation of egg quality parameters of two Hungarian ostrich populations
51-57Views:509The aim of our study was to evaluate the quality parameters, porosity and weight loss of eggs deriving from the two most significant ostrich farms in Hungary. Quality parameters included weight, length, width, shape index, egg volume, surface area, circumference and shell volume. The effect of storage conditions in both farms and the incubation technology on egg weight loss in farm “A” were also examined. The research objective was to impart a comprehensive knowledge on egg quality parameters of the main ostrich populations in Hungary and to compare the trios and the farms with each other and the international literature. We could reveal significant differences between trios in all egg quality traits. In conclusion, the shorter and the narrower the eggs were, the more spherical shape they had. Narrower eggs showed smaller surface area, volume, circumference and shell volume and vice versa. Eggs from farm “B” indicated significantly greater width, shape index, surface area, circumference and shell volume than farm “A”. A significant difference was observed in weight loss during storage between the farms. Weight loss in farm “A” was a multiple of farm “B”. In farm “B” there was a weak, positive correlation between storage period and weight loss (r=0.22, P≤0.05), in farm “A” it was not significant (P=0.52). There was no relationship between the initial egg weight and weight loss either in farm “A” or farm “B” (P=0,21, P=0,69). A slight positive correlation could be noted between egg porosity and weight loss (r=0.24, P≤0.05). Pores count presented here was less than the international results. Poultry eggs contain the most pores at the blunt end, less via the equator and the least at the pointed end. In ostrich egg we found more pores via the equator against the blunt end. To draw more precise conclusions, further investigation should be carried out on porosity. Considering the fact that the length of storage period and the weight loss during incubation are in strict correlation with hatchability, we intend to extend our research aims to these traits.

Basic Research for the Development of Fertiliser Spreaders
52-57Views:225The knowledge of the physical characteristics of fertiliser particles is essential for the constructors and operators of fertiliser distributors. Among physical characteristics, the most important are the frictional and aerodynamic properties for the description of particle movement. Adjustable angled slopes, shearing boxes and various rotating disks are used to identify frictional properties. We have developed a high precision shearing box with digital force measuring cells and a distance signaller (incremental transducer) that we use for slide tests efficiently. We measured the frictional characteristics of 6 different fertilisers: the inner coefficient of friction and the coefficient of friction on ten test surfaces most commonly used in machinery, and we specified the relationship between displacement, loading and the coefficient of friction. We can conclude that the material of the frictional surface significantly influences the force of friction.
However, our experience tells us that the shearing box is not suitable for the measurement of the inner friction, since the examined particles slide on the metal surface of the shearing box in a growing extent in the course of displacement, so it does not measure the real inner friction. Therefore, in our experiment we have developed rotating shearing equipment with a constant shearing surface to identify the inner friction. We tested the equipment with fertilisers and we identified the inner frictional characteristics of 6 different fertilisers. With the developed rotating shearing apparatus we could measure the real inner friction of the particles.
To identify the aerodynamic characteristics of granules, wind tunnels and free-fall tests are used. An elutriator have been developed for our investigation. We have used fertilisers for testing the measuring equipment and we have identified the aerodynamic characteristics of 6 different fertilisers. -
Creating potential agricultural clusters in the Northern Great Plain Region
63-67Views:205The crisis of the hungarian agricultre is continuous since the ’80s. The compensation is made a dual farm system, which has created barriers to efficient agricultural production. It is confirmed by the economic indexes as well. But the most important natural resources of our country is still the land. Over the past 20 years, the government was not able to work out strategic aims and adequate system for the hungarian agriculture. In the past three decades the clusters has become the most common tool in economic development worldwide. Clusters always base on some local knowledge, and a country can be competitive on the industry in which the resources are concentrated. So the question is, is it possible to „clusterize” the
agriculture and through this develop the rural economic. -
Analysis of the efficiency of higher education systems
207-214Views:248The aim of the higher education reform process both in Hungary and in the European countries is establishing a competitive, qualitative higher education. The Education Minister of our country regularly emphasizes in his statements that the quantitative changes of he past 15 years are completed, from now the emphasis must be on quality :„a degree in itself is not sufficient, the actual knowledge behind is necessary”. To achieve
this aim, the government carried out several changes in the field of higher education in the past years, one of them was implementing a budget support system in accordance with the performance of the institutions. The objective of the three year long support agreement between the state and the higher education institutions is considering quality parameters and outputs beside and instead of normative (input-based) support. The other occurent and debated issue is the introduction of tuition fees. Although this plan was rejected by the national referendum on 9th March, 2008, some weeks ago an amendment bill was passed, which would mean bringing tuition fees back in the system.
In my paper I am examining whether the efficiency of higher education systems are influenced by the extent of the contribution of the state and the private sector to their expenses. Furthermore I’d like to find the answer to the following question: Does it matter what principles and mechanisms play role by the distribution of the state support between the institutions of higher education. -

Comparative Evaluation of the Temperaments of Charolais and Hungarian Grey Steers
14-19Views:276Animal breeding increasingly lays claim to the theoretical and practical knowledge of applied ethology. The authors’ aim was to evaluate and compare the temperaments of Charolais (CH, n= 10) and Hungarian Grey (HG, n= 10) steers, and also to determine the correlation between their temperament scores and flight speed scores. Temperament was evaluated by the results of the scale test (assessing of behaviour in a 1-5 score system, while the animal is standing on a scale for 30 seconds) and flight speed test (minutes it takes the animal to move a set distance of 1.7 m when leaving the scale), on three occasions (1, 2, 3). Data management was done by SPSS.10 (ANOVA, Mann-Whitney-test, Spearman-correlation). Results of the scale test differed significantly between breeds at the third measurement (CH: 2,9 scores; HG: 1,4 scores; P<0,01) and when evaluating the three measurements together (CH: 2,0 scores; HG: 1,37 scores; P<0,05). Concerning of flight speed score, there were significant differences between breeds of steers at each measurement (1. measurement CH: 2,77 s; HG: 4,09 s; P<0,05; 2. measurement CH: 2,89 s; HG: 5,01 s; P<0,01; 3. measurement CH: 2,46 s; HG: 5,33 s; P<0,01) and overall (CH: 2,71 s; HG: 4,81 s; P<0,001). In the case of both breeds, evaluated by measurements and overall, a negative correlation was calculated between temperament score and flight speed score, but this was significant only in three cases: CH1 (n=10) r= -0,75; P<0,01; CH1+2+3 (n=30) r= -0,44; P<0,05; CH+HG1+2+3 (n=60) r= -0,33; P<0,01). Results indicate that Hungarian Grey steers are calmer than individuals of Charolais. Animals behaving calmer on the scale left the scale, more slowly. The authors propose the use of these temperament tests in Hungarian breeding practice, in order to select too temperament animals.

Study of animal welfare status in dairy cow herds in Hungary – looking for causes of lameness
47-50Views:386In the last 20–30 years lameness in cattle was found to be third the most influential disease next to mastitis and reproduction disorders. Studies have been established to explore reasons for lameness and prevention. The problem with more robust prevention plans is that knowledge and research evidence is not strong enough to run an effective prevention plan. The aim of the research is to look for reasons of lameness by observing number of cows on 6 farms during 2 lactations. Performance data will be put together to body condition score (BCS) and lameness scores. Other examination is focused on monitoring of 40 farms. This part of the project is more related to extension, collecting and sharing solutions for decreasing lameness. Producers are advised what kind of measures are possible to reduce occurrence of lameness. Effectiveness of those actions will be measured at the end of the study. The first preliminary results show lack in almost all preventive measures needed to be taken in minimising lameness. Those areas are related to poor facilities, lack of straw, problems with labour and basic management.

Challenges – the impact of climate change on the nutritional management of Hungarian orchards
323-334Views:442The agricultural sector is increasingly exposed to both environmental and economic risks due to the phenomena of climate change and climate variability. Fruit growth and productivity are adversely affected by nature’s wrath in the form of various abiotic stress factors. Climate change and extreme climatic events are predicted to increase in intensity, frequency, and geographic extent as a consequence of global climate change. It is no doubt that frequency of unexpected climatic events and their growing rate result in an increasing amount of problems for fruit growers globally. Today, climate change impacts are the most serious problems for Hungarian fruit growers as well. It can be stated that the nutrient demand of fruit trees can be supplied only under even worse conditions.
Therefore, it is so important to know and apply adaptation and mitigation strategies in horticulture to improve fruit quality and yield. In the last ten years, at the Faculty of Agricultural and Food Sciences and Environmental Management at University of Debrecen expanded studies have been made to prove the importance of groundcover management in horticultural applications. In this mini review paper, is presented, how the university's researches contributed to the expansion of knowledge of preservation of soil moisture and what advice we can provide for fruit growers to face the challenges of climate change.

The influence of channel network silting up at Žitný Ostrov to range of interaction between surface and groundwater
23-31Views:194The movement of water resources, especially the possibilities of their regulation by interaction between surface and groundwaters are the subject matter of attention particularly during the occurrence of extreme hydrologic situation. This work presents the overview of knowledge and results which were achieved at IH SAS in this question. It can show the ways how to optimize the adjudicated processes which emerge during the requirement of emergency intervention. The solution of this task was located at the Žitný Ostrov area because this territory with their existence of channel network is suitable for studying the surface and groundwater interaction. The channel network at Žitný Ostrov was built up for drainage and also to safeguard irrigation water. The water level in the whole channel network system has an effect on groundwater level on the Žitný Ostrov and vice versa. It was been necessary to judge the impact of the channel network silting up by bed silts on the interaction between channel network and groundwater on the Žitný Ostrov. The aim was to evaluate the changes of bed silt state of Žitný Ostrov channel network and consecutively their influence on interaction processes between groundwater and surface water along the channels in the period from 1993 to present. The measurements of bed silt thickness in Žitný ostrov channel network had been started from1993, later they continued at selected profiles of three main channels – channel Gabčíkovo-Topoľníky, Chotárny channel and Komárňanský channel (for checking of the silting up variability). From 2008 the detailed field measurements of cross-section profiles aggradations along these selected three channels have been started. The objective of detailed field measurements was the determination of the silt permeability which is expressed by parameter of saturated hydraulic conductivity. This parameter was determined by two ways – as the saturated hydraulic conductivity obtained from disturbed samples of silt Kp and as the saturated hydraulic conductivity obtained from undisturbed samples of silt Kn. In the first case the granularity of silts was determined as a first step and then was computed their Kp from the empirical formulas according Bayer-Schweiger and Spacek. From undisturbed samples of silts which were extracted along the channels from top, middle and bottom layer of silts, were determined the values Kn by the laboratory falling head method. The valid values Kp on channel Gabčíkovo-Topoľníky ranged from
4,33 10-7 to 4,46.10-5 m s-1, on Chotárny channel from 5.98 10-5 to 2.14 10-6 m s-1 and on Komárňanský channel fluctuated from 1.93 10-6 – 6.09 10-5 m s-1. The valid values Kn on on channel Gabčíkovo-Topoľníky ranged from 5.21 10-8 – 4.18 10-3 m s-1 , on Chotárny channel ranged from 8.54 10-8 – 2.70 10-4 m s-1 and on Komárňanský channel fluctuated from 4.72 10-7 – 1.26 10-5 m s-1. The remarkable results were noticed by comparison of values of saturated hydraulic conductivity from disturbed and undisturbed samples Kp and Kn. On Chotárny channel the values of silt saturated hydraulic conductivity from undisturbed samples Kn approximately hundredfold decreased (from 10-6 to 10-8 m s-1). On Komárňanský channel the comparison of values Kp and Kn shown that the values Kn from undisturbed samples approximately tenfold descended against Kp.Simultaneously, the bed silts‘ impact on the groundwater recharge (saturated hydraulic conductivity of silt) was also examined. Determination of the total recharge amount was done by numerical simulation (model SKOKY) and by the so-called method of interaction formulas. These two approaches were applied at the Žitný Ostrov channel network. There were field measurements performed in monitored three main channels and adjacent to obtain correct input data. These characteristics were used for simulation and computation of total recharge along the channels. The total recharge amount was calculated for four alternatives of the surface water levels in the channel and the surroundings groundwater respectively. We chose four simplified variants with the same geological conditions in surroundings area of channels, only water levels of groundwater and in channels were modified. The results of the simulations seem to show greater impact of the silt in the case of outflow from the channels to the surroundings than the inflow into the channel from the surroundings.

Studying the reproduction-biological effect of the GPR54 receptor gene in sheep
48-51Views:390One of the main economical problems of sheep breeding is that continual production is not possible due to the seasonality of animals. Today, genes, mutations that may develop aseasonality in sheep are extensively researched in order to make the establishment of populations capable of aseasonal estrus possible.
According to the current knowledge, the GPR54 gene participates in the GnRH release from the hypothalamus, and thus in the alteration of the reproduction state of the organism. Our research is aimed to determine whether the GPR54 gene has allele variations that influence the proneness to aseasonal estrus in sheep in a different extent. Therefore, the GPR54 gene sequence of sheep is first examined. -
The Present and Future of Tokay Aszú
87-92Views:229Tokay wine is Hungary’s noblest wine. Beyond doubt, it is one of those uniquely Hungarian products, which has been without rival for centuries. Today the role of quality has become increasingly important and consumers who are ready to pay more for quality wines expect it. This wine will be able to get back its original popularity if the message of its excellence reaches the public. Knowledge of historical wine-producing regions constitutes a part of basic education and wine-marketing could take important measures to spread it since good products need to be sold properly and consumers require information about wines – with gastronomy – and wine producing regions.
With foreign invested capital, advantageous changes have been started in Tokay-Hegyalja. However, there is much still to do in order to produce, sell and consume Tokay wine on such conditions that are really worthy of a Hungaricum. It is essential to approach the famous oenologists of Europe and the world and to establish suitable production conditions for every winegrower. In addition to following consciously prepared wine-marketing directions, our country needs to make an expected name for this Hungaricum. These aims are important mainly because of approaching EU-accession. There is timely to study on what conditions Hungarian viticulture and oenology could access. It would be a great success of the Hungarian delegation if they could make current Hungarian laws of Tokay-wine-production accepted in the EU. Of course, all of these would be valid after EU-accession. During the pre-accession period, our country needs to fulfil several stipulations. For example, origin-protection, establishment of a registry system, law harmonisation, development of an institutional system.
Strengthening of home consumption has always been an inspirational tool in a product’s life cycle. It is important not only to take the requirements of foreigners into consideration and to produce for export, but we also need to satisfy the home market. Considerable stress should be laid on establishing and preserving viticulture. Increasingly, buyers expect high standards and they are ready to pay more for quality wines. They also demand appropriate professional information and consultation. So there is a lot to do and theoretical approach should be followed by action. In order to get to know what quality expectations exist, we have to examine the consumers of the Hungarian wine-market. Study of the Hungarian people’s consumption behaviour, referring to Tokay „aszú”, was closely connected with my work.
Participants of my study were consumers who buy Tokay „aszú” mainly in shopping centres, supermarkets and low-price shops specified for wine selling. Wine shops have important roles as they give opportunity for salespersons to make closer relationships with buyers. These shops could be communication channels of spreading wine culture. It would be favourable if in every town or city there were at least one wine shop giving the opportunity of consultation besides commercial activity and also providing services that support the improvement of wine culture’s position. The majority of questioned people spend less than 4.000 Forints on buying of Tokay „aszú” in a year. Results of the questionnaire survey support the fact that there is a demand for these wine-specialities, but lack of money strongly effects demand.
The Following summarises the history of Tokay wine, tasks of Hungary and the expected effects relating to EU-accession. Regulation of oenology and the wine-market, referring to quality wines and main results of the survey are also overviewed in the text. -
Methodologies in measuring risk of financial statements
117-120Views:139Aim of financial statements’ risk analysis is to optimally allocate the audit resources. That optimum point can be reached, if we achieve maximum possibility of recovery of material risks. There are more than one procedures exist for researching of optimum point or risk assessment in other word, and they are needed to use even parallel. In order to take into consideration effects of risk we need to measure them somehow. At risk assessments risks are usually some kind of result of impact and possibility. Knowledge and measurement of impacts and possibilities are far not enough for assessment of certain risks. In this study I will present a possible usable risk assessment methodology for financial audit activities with using Multi Attribute Utility Theory (MAUT in the followings).

Effect of different production types on the yield and ß-carotene content of sweet potato /cultivar Ásotthalmi- 12/
45-49Views:418Production 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.

Investigation of genetic diversity in irradiated maize lines and its relation to hybrid performance
20-26Views:712Knowledge of genetic diversity among available parental lines is fundamental for successful hybrid maize breeding. The aims of this study were to estimate (1) genetic similarity (GS) and genetic distance (GD) (based on Jaccard index) in four maize inbreed lines; (2) to classify the lines according to their GD and GS; (3) to determine hybrid performance based on GD and heterosis for yield ability in 4x4 full diallel system. We used morphological description and AFLP (amplified fragment length polymorphisms) for estimation genetic polymorphism in four maize inbred lines. We estimated the applicability of genetic similarity in SC and reciproc hybrids for prediction of their performance.
Three primer combinations were used to obtain AFLP markers, producing 207 bands, 70 of whit were polimorphic. The dendogram based on genetic similarities (GS) and genetic distance (GD) and morphological description separated four inbred lines into well-defined groups. Morphological description just with AFLP analysis showed reliable results.
