A KNOWLEDGE of the genetics of resistance to leaf •*"*• rust of wheat, Triticum aestivum L., caused by the rust organism Puccinia recondita Rob. ex. Desm., would greatly reduce the empiricism involved in practical rust breeding programs and hasten product ion of resistant varieties. Breeding for leaf rust resistance is complicated by the occurrence of many physiologic races of the causal organism. A total of 183 physiologic races has been registered by Johnston (8).
