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...
Five winter wheat cultivars, differing in resistance to Septoria tritici blotch (STB), were spray inoculated under field conditions for two years and at two locations with nine Mycosphaerella gramin...
In 2001, genetically modified potatoes carrying the ac2 gene were developed. This gene was originally found in amaranth seeds (Amaranthus caudatus) and is expressed into the fungicidal peptide Ac-AMP2...
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 ...
The technical report presents a summary of results obtained in the leaf rust race surveys carried out in Czechoslovakia/Czech Republic in the years 1966–2001. The physiologic races were determined usi...
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...
Previous studies showed that glyphosate (Gly) may chelate cation nutrients, including potassium (K), which might affect the nutritional status of soybean seed. The objective of this study was to evalu...
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...
Enhancing water use efficiencies of rain-fed maize is a requirement for sustainable maize production, particularly in areas prone to low/drought and erratic rainfall patterns. This study was conducted...
Crop is commonly grown in intercrop combinations of which cereal/legumes are the most widespread in tropical countries. The availability of low light inten-sity due to shading is the critical factor i...
Eight primocane fruiting red raspberry cultivars grown at the Experimental station "Radmilovac", a collective raspberry orchard of the Faculty of Agriculture, Belgrade University, were harvested in 20...
Food shortage is a major problem in sub-Saharan Africa as population increases. NERICA (New Rice for Africa), the high yielding rice cultivars with short growth cycle were developed to solve the food ...
Yield is the characteristic by which a cultivar is commonly judge. A cultivar may be considered satisfactory only if it is able to produce a good yield in comparison to others at various times and in ...
