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 کاملA biological and molecular characterization of some Egyptian barley genotypes which are resistant to net blotch disease.
A survey for resistance against net blotch disease (caused by Pyrenophora teres) was performed on some Egyptian barley landraces and some selected resistance and susceptible standard German barley genotypes. The results indicated that most of the Egyptian barley landraces are extremely resistant to the disease. Molecular analysis using RAPD and AFLP showed unique banding profiles for the differ...
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 کاملQuantitative expression analysis of candidate genes for Septoria tritici blotch resistance in wheat (Triticum aestivum L.)
Septoria tritici blotch (STB), caused by the ascomycete fungus Mycosphaerella graminicola (asexual stage: Septoria tritici), is one of the most important foliar diseases of wheat. In this research, quantitative expression analysis of five candidate genes for the induction of resistance to STB (PR-1, Bsi, Msr, Per, and Ppi) was conducted in the wheat cultivars ‘Seri 82’ (susceptible) and ‘Fronta...
