Publication - Characterization of Ethiopian wheat germplasm for resistance to four Puccinia graminis f. sp. tritici races facilitated by single-race nurseries(American Phytopathological Society (APS), 2019) Kotu, B.H.; Girma, B.; Tadesse, Z.; Edae, E.A.; Olivera Firpo, P.D.; Hailu, E.; Worku Denbel Bulbula; Abeyo Bekele Geleta; Badebo, A.; Cisar, G.; Brown-Guedira, G.; Gale, S.; Yue Jin; Rouse, M.N.In Ethiopia, breeding rust resistant wheat cultivars is a priority for wheat production. A stem rust epidemic during 2013 to 2014 on previously resistant cultivar Digalu highlighted the need to determine the effectiveness of wheat lines to multiple races of Puccinia graminisf. sp. tritici in Ethiopia. During 2014 and 2015, we evaluated a total of 97 bread wheat and 14 durum wheat genotypes against four P. graminis f. sp. tritici races at the seedling stage and in single-race field nurseries. Resistance genes were postulated using molecular marker assays. Bread wheat lines were resistant to race JRCQC, the race most virulent to durum wheat. Lines with stem rust resistance gene Sr24 possessed the most effective resistance to the four races. Only three lines with adult plant resistance possessed resistance effective to the four races comparable with cultivars with Sr24. Although responses of the wheat lines across races were positively correlated, wheat lines were identified that possessed adult plant resistance to race TTKSK but were relatively susceptible to race TKTTF. This study demonstrated the importance of testing wheat lines for response to multiple races of the stem rust pathogen to determine if lines possessed non-race-specific resistance.
