development of diploid pollinator for resistance to powdery mildew disease in sugar beet
for development of pollinator parent resistant to powdery mildew disease of sugar beet, relatively resistant 14442 population was used. based on resistance index, 50 resisitant plants were selected to produce half sib family(h.s.f). after random pollination between these 50 plants, seed of h.s.f was harvesed. from these 50 plants, only 39 plants had produced enough seed. next year these h.s.f w...
متن کاملanalysis of genetic resistance to powdery mildew disease in sugar beet
development of resistant variety to powdery mildew (pm) is necessary. therefore, during past years some of the sugar beet genotypes were screened to this disease in kermanshah. one of the genotypes named 14442 showed resistance to pm disease. this genotype with two male sterile lines (ms261 and ms231) was used to determine the number of genes responsible for resistance to disease. crosses betwe...
متن کاملEfficiency of resistance genes in wheat to powdery mildew in some centers of disease incidence in Iran
Wheat powdery mildew caused by fungal pathogen Blumeria graminis f.sp. tritici is a destructive wheat disease, occurring in regions with cool and humid climates. In order to investigate the changes in pathogenicity of the disease and to identify the effective genetic source of resistance, a total of 29 wheat genotypes with different resistance major genes (Pm) were studied in two hotspots of Go...
متن کاملCharacterization of resistance mechanisms to powdery mildew (Erysiphe betae) in beet (Beta vulgaris).
Beet powdery mildew incited by Erysiphe betae is a serious foliar fungal disease of worldwide distribution causing losses of up to 30%. In the present work, we searched for resistance in a germplasm collection of 184 genotypes of Beta vulgaris including fodder (51 genotypes), garden (60 genotypes), leaf (51 genotypes), and sugar (22 genotypes) beet types. Resistant genotypes were identified in ...
متن کاملgenetic analysis of powdery mildew resistance in some barely lines
powdery mildew, caused by blumeria graminis hordei, is currently the most serious foliar disease of barley in worldwide and reduced barley yield. the use of resistant cultivars is an efficient, economical and environmentally way to control of powdery mildew in barley. in this research a half diallel design was used for genetic analysis of resistance to powdery mildew (bgh) in barley. six barley...
