Seedling resistance to physiologic race 111 (culture 111‐SS2) of Puccinia graminis f. sp. tritici was conditioned by two and three independent genes, respectively, in the durum wheat P.I. 94701 and the common wheat Reliance. The infection type was lower when P.I. 94701 genes for resistance were combined in a single plant than when they occurred singly. One of the P.I. 94701 genes also conditioned moderate resistance to physiologic race 15B (culture 15B‐SS1). Low infection types masked high infection types in plants carrying two or three genes for resistance from Reliance.
