Characterization 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 کاملComparison of ITS sequences from UK and North American sugar-beet powdery mildews and the designation of Erysiphe betae.
Powdery mildew of sugar beet, a disease of major economic significance, was first described at the beginning of the 20th century, and since then there has been some confusion over the correct taxonomic identity of the causal agent. In Europe, the fungus was initially classified as the novel species Microsphaera betae, later re-named Erysiphe betae, whilst in America it was identified as E. poly...
متن کاملdevelopment 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 کاملa study on genetic diversity of iranian populations of erysiphe betae(vanha) weltzien causal agent of sugar beet powdery mildew using rdna-rflp method
a total of 105 isolates of erysiphe betae from different regions of iran were investigated. for probable polymorphism of its-5.8s regions using pcr-based rflp, the mentioned fragments were amplified via pcr by its1 and its4 primers and subjected to 1.5% agarose gel electrophoresis. pcr products were digested by haeiii, alui, taqi, hindiii, cfoi, ecori, mspi, saci and rsai res and the digestion ...
