Evaluation of advanced bread wheat Genotypes against dominance races of wheat stem rust under greenhouse conditions in Guji Zone, Southern Ethiopia

Abstract

Wheat (Triticum spp.) is one of the most important staple cereal crops cultivated for food worldwide including Ethiopia. Nevertheless, production and productivity of this crop is troubled by various factors, of which wheat stem rust caused by Puccinia graminis f.sp. tritici considered as the main diseases of wheat hindering the production. Hence, the study was aimed to evaluate the reaction of advanced bread wheat lines against virulent races. Forty four advanced bread wheat lines evaluated for their reactions against the dominant/virulent races TTKTT, TKTTF, TTTTF, TKKTF, and TTRTF. Ten advanced bread wheat lines, namely; ETBW-164008, ETBW-17.148, ETBW-9452, BW-17-2020, BW-17-4018, ETBW-17-133, BW-164006, BW-17-4456, BW164002 and BW-164004 showed resistance reactions (IT = fleck (;) to 2) to all dominant races. Though, to come up with a precise and reliable recommendation, the experiment should be done at adult stage resistance and the evaluated lines should be used for the future breeding program.
