| Abstract: | Summary The Australian Bunt Collection, obtained from infected crops between 1962–1977, has been classified into races, based on the differential reactions to ten known bunt resistant genes. Eight physiologic races of Tilletia laevis and three of T. tritici were identified. No race had virulence against the genes Bt3, Bt5, Bt8, or Bt10, of wheat. Consequently four major genes are available for breeding Australian wheat cultivars with resistance to common bunt. |
