Abstract
An accession of A. sterilis, Canadian Avena (CAV) accession 1387, which originated from Israel, was susceptible in the seedling stage, but resistant in the adult plant stage to 6 races of Puccinia coronata. Crosses of resistant derivatives of CAV1387 with the susceptible A. sativa lines RL3069 or Sun II resulted in F2 segregation ratios of 1 resistant:2 moderately resistant:1 susceptible plants. The adult plant resistance in CAV1387 was conferred by a single partially dominant gene, designated as Pc-69. This gene confers effective field resistance to the races of P. coronata that occur in western Canada.This publication has 4 references indexed in Scilit:
