Genetics of resistance to race TTKSK of Puccinia graminis f. sp. tritici in Triticum monococcum.
Race TTKSK (or Ug99) of Puccinia graminis f. sp. tritici possesses virulence to several stem rust resistance genes commonly present in wheat cultivars grown worldwide. New variants detected in the race TTKSK lineage further broadened the virulence spectrum. The identification of sources of genetic resistance to race TTKSK and its relatives is necessary to enable the development and deployment o...
متن کاملA major gene for powdery mildew resistance transferred to common wheat from wild einkorn wheat.
ABSTRACT A major gene for resistance to wheat powdery mildew (Blumeria graminis f. sp. tritici = Erysiphe graminis f. sp. tritici) has been successfully transferred into hexaploid common wheat (Triticum aestivum, 2n = 6x = 42, AABBDD) from wild einkorn wheat (Triticum monococcum subsp. aegilopoides, 2n = 2x = 14, AA). NC96BGTA5 is a germ plasm line with the pedigree Saluda x 3/PI427662. The res...
متن کاملinheritance of resistance to powdery mildew (erysiphe graminis f. sp. hordei) in barley
two barley (hordeun vulgare l.) genotypes, radical and cwb, with good to moderate levels of resistance to powdery mildew were crossed with a highly susceptible cultivar (afzal) to determine the genetics of resistance. the parents, fl, f2 and f3 generations of each of the two crosses, were evaluated for powdery mildew resistance in the glasshouse and field at the college of agriculture in karaj ...
متن کاملPyricularia graminis-tritici, a new Pyricularia species causing wheat blast
Pyricularia oryzae is a species complex that causes blast disease on more than 50 species of poaceous plants. Pyricularia oryzae has a worldwide distribution as a rice pathogen and in the last 30 years emerged as an important wheat pathogen in southern Brazil. We conducted phylogenetic analyses using 10 housekeeping loci for 128 isolates of P. oryzae sampled from sympatric populations of wheat,...
متن کاملMarkers Linked to Wheat Stem Rust Resistance Gene Sr11 Effective to Puccinia graminis f. sp. tritici Race TKTTF.
Wheat stem rust, caused by Puccinia graminis f. sp. tritici, can cause severe yield losses on susceptible wheat varieties and cultivars. Although stem rust can be controlled by the use of genetic resistance, population dynamics of P. graminis f. sp. tritici can frequently lead to defeat of wheat stem rust resistance genes. P. graminis f. sp. tritici race TKTTF caused a severe epidemic in Ethiop...
