Abstract

In the 1989/90 growing season in Canterbury, New Zealand, crops of the wheat cultivar Brock, previously resistant to Puccinia striiformis, were found to be heavily infected with stripe rust. Seedling and adult plant tests were carried out on cultures of P. striiformis from cv. Brock using differential cultivars with known resistance genes. Cultures from cv. Brock conform to the pathotype 106E139A-, but have increased pathogenicity to wheat cultivars with the adult plant resistance gene Yr14. Results also suggest that cv. Brock contains two stripe rust resistance genes; Yr7, a seedling resistance gene, and Yr14.
