Assessment of advanced Kenyan selected wheat lines for resistance to the prevailing stem rust races (Puccinia graminis f.sp.tritici) in Kenya

Wheat stem rust caused by Puccinia graminis f. sp. tritici (Pgt) is one of the most important diseases of wheat, worldwide. New sources of resistance to stem rust could be found in synthetic hexaploid wheat (SHW) genotypes due to their high genetic diversity. In order to recognize the genetic structure of the population of the stem rust, following race analysis of 12 Pgt isolates, resistance of 348 SHW genotypes were evaluated using the infection type on a scale of 0 to 4 ratio to the four selected isolates from Gorgan and Broujerd (in 2014 and 2015) at seedling stage using randomized complete block design with two replications. Based on the reactions of differential wheat genotypes, the Pgt races TKTTF and TTTTF were identified among all isolates displaying virulence on the stem rust resistance genes Sr5,
