Evaluation of a set of introgressive spring bread wheat lines developed for resistance to stem rust race Ug99 + Sr24 (TTKST) at the Southeast Agricultural Research Institute

Under conditions of a natural stem rust epiphytotic caused by Puccinia graminis f. sp. tritici race Ug99 + Sr24 (TTKST), a set of introgressive spring bread wheat lines developed at the Southeast Agricultural Research Institute was evaluated at KARI's international stem rust screening nursery (Kenya). New sources of resistance to the pathogen and effective resistance genes have been revealed.
