棉花是重要的工业原材料和天然纤维材料,相比于其他作物,陆地棉的遗传多样性极低,解析其形成原因,对棉花的遗传改良具有重要意义。研究人员通过对两种不同基因型的陆地棉进行全基因组比较分析,发现A08染色体上存在着大片段的遗传变异。该倒位能够将已发表的陆地棉核心种质资源材料分为两类,与利用SNP基因型重构的进化树的分类和主成分分析结果高度一致,表明陆地棉种内可能产生了分化。利用人工创制的群体和陆地棉核心种...
The scientific report presents results of our studies on the gene Pch1, conferring resistance to eyespot disease in wheat, caused by the fungus Occulimacula spp. The presence of the gene Pch1 in wheat...
Winter wheat cultivars recently registered in the Czech Republic were tested in three-year field tests for resistance to common bunt. Seeds were inoculated with a mixture of local strains of Tilletia ...
In the present research, we aimed to detect and evaluate the level of long terminal repeat (LTR) retrotransposons (WIS2, Wilma, Daniela, and Wham) intraspecific variability and intron polymorphism for...
In the last two decades, resistance to the powdery mildew pathogen has been investigated in a large number of barleys in the Czech Republic. Several tens of winter barley cultivars were identified wit...
Changes in genetic diversity of peas bred in the Czech Republic and in former Czechoslovakia since the mid-20th century were analysed using 38 molecular marker loci, including retrotransposons and mic...
Varietal Characterization of Tomato Cultivars Based on Rapd Markers
Estimation of genetic parameters would be useful in developing appropriate selection strategies. Heritability is a measure of possible genetic advancement under selection. The research work pertaining...
Water deficit is one of the important factors limiting crop production in arid and semi-arid regions. This research was conducted in 2007 and 2008 to investigate field performance of three chickpea cu...
Sweet cherry cultivars display a self-incompatibility system that restricts self-fertilization and fertilization between cultivars bearing identical S-alleles. PCR-based S-allele typing system for swe...
The genetic background of the highly palatable rice cultivars developed by Fukuoka Agr, .Res.Cent.was studied and compared with the high yield cultivars developed by Kyushu Natl.Agr.Exp.Stn.and Miyaza...
Eighty-five lotus cultivars including interspecific hybrids, Nelumbo nucifera and N. pentapetala (Walter) originated from China (50), Japan (32), India (2) and America (1) were evaluated by inter-simp...
Genetic relationships between cultivars are estimated either by coefficient of parentage, which is calculated using the database of cultivars lineage, or from genetic distance, which is calculated ba...
The objective of this study was to establish the technology to identify barley cultivars by the DNA markers for the purpose of managing the foundation seeds and for protecting the breeder’s right and ...
