[Genealogy-based comparative analysis of loose smut resistance of spring common wheat cultivars].
Comparative genealogical analysis was conducted for loose smut-resistant and susceptible common wheat cultivars of three regions: Russia, Canada, and India. Pedigree analysis of differentiator varieties revealed several sources of the Ut1, Ut3, and Ut4 genes. Tracking resistance transmission in extended pedigrees allowed identification of resistance donors, sources, and, in some cases, putative genes in Russian, Canadian, and Indian cultivars. A contingency table was constructed with the data on resistance or susceptibility of 839 common and durum wheat cultivars and demonstrated a significant association for resistance to two, loose and stinking, types of smut.
