The Collared Dove conquered continent areas within a few decades. Causes and dispersion pattern of expansion has been investigated in several studies. However, the relationship between the geographic distribution and genetic structure of populations has not been researched. We used 152 individuals from 19 countries in this study. We analyze a 6...50 bp long mitochondrial COI sequences of each individuals. We were performed Spatial Autocorrelation Analysis, Principal Component Analysis and analysis of the genetic discontinuity in this study. Under 2500 km distance was a positive correlation between the genetic differentiation and different geographical areas. Hidden genetic barriers were found only Carpatian Basin. Could not be detected signs of genetic isolation in other regions. This will probably due to the unevenness of the sample collection, because these areas proportionally much fewer sequences were available. Therefore, is worth repeat this analysis after further sample collection, in the future.
Knowledge 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 per...formance 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. In view of genetic distance, the UDL 1 line and their linear and reciprocal crosses showed significant heterosis effect, which was confirmed by heterosis calculation based on grain yield.

Its genetic structure is affected not only by last glacial, even by human activities (hunting, agricultural activities), isolation of such areas or competing for food resources. According to literature datas brown hare populations has different genetic variants in Europe, however its evolution, phylogenetics has not studied well.
Because of the feeding technology innovation, accelerated transport and communication facilities breeds of high performance breeds replaced local autochone breeds worldwide. These latter species however have an important role in gene conservation. Hungarian cold-blooded horse breeding stock are lacking pedigree, the actual founder breed mares a...re not known. For this reason, it is an major priority defining the genetic backround of the existing flock, for that breeding could operate with purposeful using of origin maternal founders. In the present study 195 cold-blooded Hungarian mares tail and mane sample were analized. Our analysis was carried out between 15531–15752 base pairs in mithocrondial DNA D-loop region, which reported a total of 222 base pairs. Fourtyone polymorphic sites were determined, which resulted in 39 haplotypes (h=39). The average pairwise differences were k=6.825. High haplotype and nucleotide diversity values were observed (Hd=0.968±0.003, π=0.026±0.003). Based on the previously defined variable positions of haplotypes defined by Jansen et al (2002), we groupped our haplotypes into haplogroups. 23 percent of the studied population (45 mares) belonged to haplogroup F1. Nearly 97% of the analyzed population was classified into one of eight haplogroups defined by Jansen.et al. (2002). This study gives genetic information nearly 25% of the Hungarian population. Another possibility would be patterning more mares or involving more genetic marker in the study which will assuming the possibility of a more comprehensive analysis.
Fossil datas showed that the lagomorphs appeared in Asia during the later Eocene and leporids separated from ochotonids during the Oligocen or Upper Eocene. During the Pleistocene, climatic changes induced major shifts in species distributions, forcing them to refugia.
In Europe, the continuous oscillations led to the production of greater s
The use of molecular markers to enhance plant breeding efforts is being widely studied. DNA-based fingerprinting technologies (RAPD and AFLP) have proven useful in genetic similarity studies. We estimated different maize (Zea mays L.) inbred lines and hybrids originated from mutant ones based on their genetic differences.
We carried out RAPD
Hundred animal species have disappeared during the last century. By this time, approximately one-third of domestic animals have been in the endangered category. Hucul horses are also in this category; furthermore saving the genetic diversity beside the race preservation is an important challenge as well. The number of mares and stallions is onl...y one of the expressive elements of genetic diversity; together with their quality determine the genetic variability of this breed. Beyond that, if an exact breed can originates from more founders, it can be more renewed genetically. Stud book documents these data by registering the mare families and stallions’ genealogical lineage. Molecular genetics, especially mitochondrial DNA analysis can make the precise identification of mare families possible. As a result of these molecular based methods, protection of genetic diversity, as well as breed preservation became more reliable. After the primer designing, the optimal primer pair was chosen which targets a 1092 bp length DNA sequence in the cytochrome b region. After the successful PCR optimalisation, we determined 170 Hucul mares’ sequences. According to our results, the samples compose ten haplotypes, which are much less, than the registered number of mare families in the stud book. Further investigations are needed to reach more representative results, and drawn the further consequences.
The cosmopolitan Phoma genus contains mainly phytopathogenic, opportunistic parasites, and saprophyte fungal species. Up to now, the characterization of Phoma species and other taxa of Phoma has been determined on the basis of morphology on standardized media, and gene sequence analysis was only used as a confirmative or distinctive complement....
In this study, we tried to find molecular markers which can be used as phylogenetics markers in the molecular based classification in the Phoma genus.
We employed a part of the translation elongation factor 1 subunit alpha (EF-1α=tef1) containing both introns and exons and ITS region containing the internal transcribed spacer regions 1 and 2 and the 5.8S rDNA, as potential genetic markers to infer phylogenetic relationships among different Phoma taxa. Twelve different Phoma species sequences were analysed together with the closely related Ascochyta ones. The constructed phylogenetic trees, based on tef1 and ITS sequences, do not support the traditional Phoma sections based on morphological characterization. However, we managed to distinguish between the Phoma strains and Ascochyta species by comparing their tef1 sequences through parsimony analysis. We proved that a tef1 can be a useful phylogenetic marker to resolve phylogenetic relationships at species level in Phoma genus.
Both parsimony sequence analyses confirmed that the Phyllosticta sojicola species is identical to the Phoma exigua var. exigua species as Kövics et al. (1999) claimed. However, the evolutionary distance by ITS sequences within Phoma species is too small to get well based consequences for the phylogenetic relationships of Phoma genus.
Further investigations would be necessary to clarify whether the tef1 and ITS sequences as phylogenetic molecular markers are well suited for the classification of Phoma species.
The authors made their analysis based on the body measurements of 3080 Hungarian Sport Horse mares listed in the Hungarian Sport Horse Studbook. Height at withers by stick, height at withers by tape, heart girth and cannon-bone circumference were measured in Hungarian Sport Horse mare performance tests.

There were low phenotypic correlations between frame (as conformational trait) and height at the withers (measured by tape and stick) and heart girth.
We carried out phylogenetic study analyzing sequences of genetic markers in the taxonomy of Phoma and Phoma-like fungi. Different species of Phoma and Phoma-like fungi occurring on soybean (Phoma pinodella, Phoma sojicola, Phyllosticta sojicola, Phoma exigua var. exigua) are difficult to identy because of their high morphological and symptomati...c similarities.
Twenty-two isolates of nine different Phoma species were obtained from reference culture collections. Seven of them were isolated from soybean, the others were collected from different hosts.
The Phoma isolates were firstly characterised by morphologically, and then we employed a part of the gene responsible for the synthesis of translation elongation factor 1 subunit alpha protein (tef1), ITS region, as well as β-tubulin partial sequences as potential genetic markers to infer
phylogenetic relationships among different Phoma species..Finally, their ITS and tef1 sequences were sequenced and analysed by Bayesian approaches.
According to phylogenetic trees inferred by Bayesian analysis of tef1, ITS and β-tubulin sequences, different Phoma species can be separated proving that these phylogenetic markers are well suited for phylogenetic studies of Phoma species. However, the phylogenetic tree does not support the traditional Phoma sections based on morphological characterization.
Bayesian analyses of the three sequences confirmed that the Phyllosticta sojicola species is clustered with the Phoma exigua var. exigua group and the Phoma sojicola is grouped with Phoma pinodella group. The molecular data provide evidence for reclassification of formerly mentioned soybean pathogens.
Staphylococcus aureus is a very important pathogen for dairy farms and milk processing plants. Subclinical mastitis is often caused by this species, and it can contaminate bulk tank milk when milking cows are suffering from mastitis. Additionally, thermostable enterotoxins (SE) produced by some types of this bacterium can cause food poisoning.<...br>The aim of our research was to examine the number of S. aureus in bulk tank milk in two dairy farms and the enterotoxin-producing ability, genetic relation (pulsotype) and antibiotic resistance of S. aureus strains from different sources (bulk tank milk, udder quarter milk and environment).
The results show that the mean number of S. aureus of bulk tank milk of two farms significantly differed (P<0.05). Fourteen isolates were selected for further molecular genetic studies (five isolates were from bulk tank milk and nine isolates were from udder quarter milk). S. aureus was not recovered from the environmental samples. Three of the fourteen isolates (21.4%) tested by multiplex PCR were positive for SE genes. Two isolates carried one gene (seb) and one isolate carried two genes (seg and sei). The fourteen strains were classified into three pulsotypes and two subtypes at 86% similarity level. Isolates from bulk tank milk (n=5), were divided into 2 pulsotypes (A, C) and one subtype (C1). The isolates from udder quarter milk (n=9) belonged to three different pulsotypes (A, B, C) and two subtypes (A1, C1). The distribution of pulsotypes in the present study revealed genetic relationship between S. aureus isolated from udder quarter milk and bulk tank milk. This could be explained by the fact that in farms with a high number of infected cows, these cows could represent the main source of contamination. The results of the antibiotic resistance investigations show, that all strains were susceptible to methicillin, cefoxitin, lincomycin, tetracycline, erythromycin and sulfamethoxazole/trimethoprim. Thirteen out of fourteen strains were resistant to penicillin (A and C pulsotypes, A1 and C1 subtypes) and just one isolate was susceptible (B pulsotype) to all antibiotics tested.
The aim of this paper is to estimate heritabilities and to compare different fitted models for Hungarian Sporthorse showjumping results. Our analysis is based on the show-jumping results between 1996 and 2004. The repeatability animal model for the evaluation of the test results included the fixed effects of gender, breeder, rider, age, y...ear of competition, type of competition, height of fence and number of starters. Variance and covariance components were estimated with VCE-5 software package. Fitting of the models were evaluated with log-likelihood values and Akaike’s information criterion (AIC). Heritability was low in all cases.
The lowest goodness-of-fit model was height of fence-error score and the best-fitting genetic model based on AIC was model using cotangent transformation.

The evolved three usage breed was durable and resistant, however in comparison with the high-productivity breeds was less competitive. The dramatic lay-off, and the endangered status of the breed requires a conservation programme. University of Debrecen took the investigation of the Hungarian population and it’s detailed genetic studies. Within this research project among others we carry out body measurements and rates of the body traits. Depending on these results, we may decide on the subsequent gene-reserving objects. Based on body measurements and live weight we established that the breed at Mikóháza favours to the one lived in Hungary in the 1960’s, and to another, named Ukrainian Carpathian Brown. Compared to the earlier data (Horváth, 1966) smaller body traits can be seen. Our livestock is proportionately smaller than the other breeds in height at withers, as well as in live weight. Based on the comparative analysis, we established, that – thanks to the aware sorting – the imported individuals represent the ancient, primitive Carpathian variant.
the Carpathian Basin were involved into our examination, which aimed at genotyping their accessions. DNA fingerprints of 101 varieties were determined with 6 microsatellite markers till 2005, resulting in successful discrimination of the accessions. Based on these results for pedigree determination, even more cultivars and primers were involved... into the analyses. For studying the origin of Csabagyöngye and for proving the parent-progeny relations of Irsai Olivér and Mátrai muskotály, 19 microsatellite markers were applied, while 11 were selected for tracing the origin of Királyleányka. Genetic distances between the varieties were estimated with cluster analysis and demonstrated by dendrogram, proving that the varieties can be discriminated from each other based on the microsatellite allele sizes. Pedigree of Irsai Olivér and Mátrai muskotály has been confirmed by microsatellite allele size results, searching for the parents of Csabagyöngye and Királyleányka is in progress, since the molecular-marker based pedigree does not correspond with the putative origin of these cultivars. Our results excluded progeny-parent relationships in the
Csabagyöngye-Bronnerstraube-Muscat ottonel (Ottonel muskotály) and the Királyleányka-Kövérszőlő combinations.
The cosmopolitan Phoma genus contains mainly phytopathogenic, opportunistic parasite, and saprophyte fungal species. Up to now the characterization of Phoma species and other taxa of Phoma has so far been determined on the basis of morphology on standardized media, and gene sequence analysis was only used as a confirmative or distinctive comple...ment.
In this study we have tried to study phylogenetic relationships by maximum likelihood method in the Phoma genus. We employed a part of the gene responsible for the synthesis of translation elongation factor 1 subunit alpha protein (tef1) containing both introns and exons, a part of the gene responsible for synthesis of tubulin protein and ITS region containing the internal transcribed spacer regions 1 and 2 and the 5.8S rDNA as potential genetic markers to infer phylogenetic relationships among different Phoma taxa. Twenty-four isolates of eleven different Phoma species were firstly characterised by morphologically, and then their tef1, tubulin and ITS sequences were sequenced and analysed by maximum likelihood method carried out by PAUP*4.0b program. According to constructed phylogenetic trees, the different Phoma taxons are well separated. However these trees do not support the traditional Phoma sections based on morphological characterization.
The maximum likelihood analyses of all three sequences confirmed that the Phyllosticta sojicola species is clustered with the Phoma exigua var. exigua group and the Phoma sojicola is grouped with Phoma pinodella group. The experienced molecular evidences initiate the demand of reclassification of formerly mentioned soybean pathogens.

The increased demand in the foreign markets for the mangalitza pork, changes in the domestic consumer perceptions have increase the number of sows and breeders. After the European Union’s accession started a significant growth in the sector, which was due to the target programme from the year of 2005 for the keeping of animals representing high genetic value, as the breed is indigenous. From 2008 continuous decline can be observed. The main reason for the decrease was the drastic growth of feed costs because of the drought damage in 2007, and the global economic crisis. Since 2010, a further period of supports has been in place, it extands the willingness to keep mangalitza pigs and the number of sows continuously increasing. On the basis of the average farm size (58 sows/farm) in 2011 it can be stated, that after our EU’s accession the medium-sized farms became stronger. To evaluate the geographic concentration of the mangalitza livestock it was analysed the data of sow number among the years of 2000 and 2011. The geographic concentration of mangalitza stock has a medium value over each year under the survey period, except the years of 2004–2007, when the values of Herfindahl-Hirschman index (HHI) have low degrees. Due to the subvention period of indigenous breeds it was established more mangalitza farms in different parts of Hungary. Despite of the growth since 2000, numerous problems are in the segment. The aim of the study is to find out the sectoral problems, which are completed with the objectives tree and draw up the main activities to solve the problems. After estimating the SWOT-matrix according to the methodology of the strategic analysis and the discussions with the secretary of National Association of Mangalitza Breeders is prepared the sectoral problem- and objectives tree. The core problem of the mangalitza sector is that the origin of mangalitza products are not certified in the domestic markets. The reason of it is that the breeders don’t request the certificates of fattening pigs, so it can appear not real mangalitza product on the markets as mangalitza. To solve the problems it is drawn up different suggestions in the objectives tree. This analysis is an useful tool for the decision makers in the mangalitza sector to evolve strategic plans on behalf of the efficient cooperations among chain actors.

The soil of the trial is lime-coated chernozem, with a humus layer of 50–70 cm.
The main aim of this study was to analyze sources of variability for coat colour expressed as a quantitative trait as well as to determine non genetic factors influencing horse colour variation and shades. Traditional Hungarian horse breeds such as Lipizzan (grey), Gidran (chestnut), Shagya Arabian and Arabian Pure Bred (grey) and Nonius (bay a...nd black) horses were involved in the current study. We report results using direct measurements of horse coat colour using objective colorimetric dimensions and a spectrophotometer for determining hair melanin. Correlation analysis indicated that the single biological component that correlated best with the total melanin content of horse hair is the L* value (r=-0.858, p<0.0001). Subjective colour classes and coat colour variables L* and a* were obviously related, with R2 values of 0.88 and 0.46 respectively, with a lower R2 for b* of 0.22 (all p<0.001).
Combining ability estimation is an important genetic attribute for maize breeders in anticipating improvement in productivity via hybridization and selection. This research was carried out to investigate the genetic structure of the 27 F1 maize hybrids established from nine lines derived from Maize Research Department and three t...esters, to determine general combining ability (GCA), determine crosses showing specific combining ability (SCA) and superiority percentages for crosses. Nine lines, three testers, 27 F1 hybrids and two check commercial hybrids (SC162 and SC168) were studied in randomized complete block Design (RCBD) with three replications during 2016. The results of mean squares showed that significant and highly significant for most studied traits (days to 50% tasseling, days to 50% silking, plant and ear height, ear position, ear length, no. of kernels per row, 100-kernel weight and Grain yield). Estimates of variance due to GCA and SCA and their ratio revealed predominantly non-additive gene effects for all studied traits. Lines with the best GCA effects were: P2 (line 11) and P6 (line 21) for grain yield, for testers Gm174 and Gm1021 had significant GCA effects for grain yield. The hybrids P5×Gm1021, P6×Gm1021, P7×Gm1021, P8×Gm1002, P9×Gm1002 had significant and negative SCA effects for grain yield. Crosses P1×Gm174, P2×Gm1002, P5×Gm1021, P6×Gm174, P6×Gm1021, P7×Gm1021, P8×Gm1002, P9×Gm1021 were the best combinations manifested and significant superiority percentages over than check varieties (SC162 and SC168) for most studied traits. Therefore, these hybrids may be preferred for hybrid crop development.

The traditional Hungarian horse breed, Gidran has been close to the edge of extinction several times. Despite the multiple bottleneck effect, the breed has retained a part of its genetic variability, and performed prominently in carriage driving and show-jumping competitions. Maintaining of the Gidran breed is important in the point of view of...world heritage; because besides Hungary, smaller Gidran populations exist only in Bulgaria and Romania. Taking advantage of the special inheritance features of mtDNA, our study focused on two mtDNA regions of Gidran mares. Altogether, 251 hair samples from various Hungarian studs were examined. The analysis was successfully made in case of 251 samples of the cytochrome b and in case of 246 samples of D-loop regions. Because of the distinct mutation rates of the two mtDNA markers, the number of the haplotypes and the way of grouping samples into haplotypes was different. Our key finding was that most haplotypes may be compatible with mare families of the stud book; however incidental mistakes in stud book have occurred only in a few cases. Our results indicate the importance of the preservation and breeding those mare families, which are molecular genetically more diverse than the others, and are in the edge of extinction.
Morphological diversity of melon (Cucumis melo); phenotype reconstruction of a medieval sample. Morphological diversity among 47 melon (Cucumis melo) cultivars and landraces from Hungarian germplasm collection (ABI, Tápiószele) were analyzed with an ultimate aim to characterize morphologically cv. Hógolyó, which showed the closest genetic s...imilarity to a medieval melon recovered from the 15th century. Cultivars based on fruit morphology were grouped into the three main types of melon as reticulatus, cantalupensis and inodorus. Cluster analysis (by SPSS-11) based on 23 morphological (quantitative and qualitative) traits recorded revealed an extreme diversity among accessions, nevertheless cultivars were clustered into main melon clusters with only two exceptions of inodorus type cv. Zimovka J. and Afghanistan. Cultivars Sweet ananas and Ezüst ananász; and two Hungarian landraces Kisteleki and Nagycserkeszi showed close similarity. Cultivars Hógolyó and Túrkeve of inodorus type
were also grouped in one cluster, which provide insight into the morphological reconstruction of the medieval melon recovered from the 15th century. These results also indicate that old Hungarian landraces could be re-introduced into breeding programs for broadening genetic base of melon.
This paper gives a summary of the possibility for applying genomic information for breeding value estimation in beef cattle breeding. This process is called genomic prediction and is now widely used in dairy cattle globally as well as in some beef and sheep populations. The advantage of genomic prediction is a more accurate estimate of the gene...tic merit of an individual at a young age thereby facilitating greater annual genetic gain, predominantly through shorter generation intervals. Genomic predictions are more advantageous for sex-linked (e.g., milk yield), low heritability (e.g., fertility) and difficult-to-measure (e.g., feed intake) traits. The larger the reference population, on average, the more accurate the genomic predictions; additionally, the closer genetically the reference population is to the candidate population, the greater the accuracy of genomic predictions. Research is continuing on strategies to generate accurate genomic predictions using a reference population consisting of multiple breeds (and crossbred). Retrospective analysis of real-life data where genomic predictions have been operation for several years clearly shows a benefit of this technology.
Hungary lies on the northern edge of rice production area. According to this, the climatic conditions area not perfect for this species. The production area of rice involves typically the poorer quality soils, however these meet the requirements of rice. In Hungary exclusively domestic types are grown which have high yield and good quality and...these are usually wore successful than foreign types. On the other hand, these Hungarian types should be improved considering safety in production. Nowadays, rice is grown in large scale companies with 300-1400 hectares, where production technology already exists, machinery is suitable, however the latter one a little bit old.
The average yields of the analysed companies were 3-4 t/ha in the past few years, which were a little bit above the national averages. The operating cost per hectare is almost 200 thousand HUF, from which the main part is the cost of machinery (35%) and the material cost (34%). The main part of the latter one is the irrigation costs (30%). The average cost, calculated from the total production cost, is 80 thousand HUF/t. Considering the above-mentioned costs and the price of rice (75 thousand HUF/t) it can be stated that the profitability of the rice sector is not the best, the cost rated profitability is -6.6%. According to the results of this analysis possibilities for the increase in profitability and improvement are increased subsidies and market price, as well as genetic improvement.
The Hungarian Grey Cattle breed is a ‘success-story’ of the national genetic conservation work. Traits of the breed have been subjects of several research projects, although many relationships remained unclear. Our present research results were meant to call attention to a less emphasized trait of the breed: the different horn colour variet...ies. Research work was carried out in the Hungarian Grey stock of the Hortobágy Non-profit Company for Nature Conservation and Gene Preservation. Ratio of the three main horn colour varieties (white, ‘cardy’, green) were determined in the observed female, male and steer stocks. Our results showed no significant differences (P<0,05) in the distribution of the horn colour varieties of the female and bull stocks, and of the female and steer stocks. We found that on the basis of the ratio of white colour, four sub-categories can be distinguished within the ‘cardy’ colour variety. Results of the statistical analysis (P<0,05) confirmed that the colour of the horn and the ratio of the black part on the horn tip are two different traits.
Hungarian draft is a horse breed with a recent mixed ancestry. It was developed in the 1920s by crossing local mares with draught horses imported from France and Belgium. To genetically characterize the breed and to set up the basis for a conservation programme, we have employed a molecular marker: a 256-bp D-loop mitochondrial DNA fragment. We... analyzed 124 horses representing Hungarian draft horses to assess the maternal phylogeography of the breed. Sequence analysis of a 256-bp segment revealed a total of 34 haplotypes with thirty-four polymorphic sites. High haplotype and nucleotide diversity values (Hd=0.953±0.001; π=0.024±0.001) were detected. The average number of pairwise differences were k=5.998. This breed counts 800 mares today, and only survive due to breeding programmes, this way each haplotype frequency depends on the extent to which mares are involved into the breeding. The reduced number of surviving maternal lineages emphasizes the importance of establishing a conservation plan for this endangered breed. Due to the revealed 34 polymorphic sites we could presuppose twelve maternal linages, which could be a first step for making a breeding programme.
