Spot Blotch, Net Blotch, and Stripe Disease of Barley
Spot blotch is caused by Helminthosporium sativum or H. sorokinianum = Drechslera sorokiniana (Bipolaris sorokiniana). The disease is widespread in Illinois and is believed to lower potential barley yields by 1 to 3 percent; also, the bushel weight. The causal fungus affects all parts of the plant and produces a variety of symptoms, from a seedling blight and root rot to “Black point” of the ke...
متن کاملFine Mapping of the Barley Chromosome 6H Net Form Net Blotch Susceptibility Locus
Net form net blotch, caused by the necrotrophic fungal pathogen Pyrenophora teres f. teres, is a destructive foliar disease of barley with the potential to cause significant yield loss in major production regions throughout the world. The complexity of the host-parasite genetic interactions in this pathosystem hinders the deployment of effective resistance in barley cultivars, warranting a deep...
متن کاملMapping of quantitative trait loci associated with resistance to net form net blotch (Pyrenophora teres f. teres) in a doubled haploid Norwegian barley population
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 کاملEffects of Planting Date on Development of Net Blotch Epidemics in Winter Barley in Pennsylvania
Delserone, L. M., and Cole, H., Jr. 1987. Effects of planting date on development of net blotch epidemics in winter barley in Pennsylvania. Plant Disease 71: 438-441. The influence of planting date on fall and spring net blotch epidemics (caused by Pyrenophora teres) was evaluated with the winter barley cultivar Pennrad. Experiments were conducted in Centre County, Pennsylvania, in 1982 and 198...
متن کاملA nested association mapping population identifies multiple small effect QTL conferring resistance against net blotch (Pyrenophora teres f. teres) in wild barley
The net form of net blotch caused by the necrotrophic fungus Pyrenophora teres f. teres is a major disease of barley, causing high yield losses and reduced malting and feed quality. Exploiting the allelic richness of wild barley proved to be a valuable tool to broaden the genetic base of resistance of modern elite cultivars. In this study, a SNP-based nested association mapping (NAM) study was ...
