Abstract
The inheritance of resistance to races 15B and 56 of stem rust was studied in the varieties Africa No. 43, Kenya C9906, Kenya 338.AC.2.E.2, Egypt Na101, Veadeiro and Red Egyptian type (P.I. 170910). Each variety was analysed genetically on the basis of data obtained from a backcross to the rust susceptible variety Marquis. The interrelationships of the genes in the varieties were determined from diallel crosses. With the exception of Veadeiro, the varieties all carried various combinations of genes reported in the first paper of this series. Veadeiro has a mature plant resistance to race 15B which is probably conditioned by two additive genes not previously noted.Keywords
