Barley net blotch caused by the necrotrophic fungus Pyrenophora teres is a major barley disease in Norway. It can cause grain shriveling and yield losses, and resistance in currently grown cultivars is insufficient. In this study, a set of 589 polymorphic SNP markers was used to map resistance loci in a population of 109 doubled haploid lines from a cross between the closely related Norwegian c...
متن کاملSafeguarding Our Genetic Resources with Libraries of Doubled-Haploid Lines.
Thousands of landraces are stored in seed banks as "gold reserves" for future use in plant breeding. In many crops, their utilization is hampered because they represent heterogeneous populations of heterozygous genotypes, which harbor a high genetic load. We show, with high-density genotyping in five landraces of maize, that libraries of doubled-haploid (DH) lines capture the allelic diversity ...
متن کاملevaluation of resistance to powdery mildew and some agronomic trails of barley doubled haploid lines
ninety barley doubled haploid lines originated from crossing between six barley cultivars in cereal research department, seed and plant improvement institute, karaj, iran were evaluated for resistance to powdery mildew and some agronomic traits in field in 2007. six parent cultivars and a powdery mildew susceptible check cultivar, afzal were also included. sixty two doubled haploid lines showed...
متن کاملEvaluation of Genetic Variation and Parameters of Fatty Acid Profile in Doubled Haploid Lines of Camelina sativa L.
After cereals, oilseeds are the second-largest food reserves in the world. According to available statistics, more than 95 percent of Iran's oil needs are imported. Given the growing need for edible oils in Iran, it is important to identify fatty acids in the oilseed crops. Camelina sativa L. is an oil-medicinal plant and belongs to the Brassicaceae family that requires very little water and fe...
