A MONOSOMIC ANALYSIS OF STEM RUST REACTION AND AWN EXPRESSION IN REDMAN WHEAT

Using the recently developed monosomic aeries of Redman spring wheat in crosses with Prelude, genetic studies were undertaken on stem rust reaction and awn expression. It was found that chromosomes III, VIII and XIII of Redman carry factors for adult plant resistance to race 56 of Puccinia graminis Pers. f. sp. tritici Erikss. & Henn. These factors are complementary and dominant in action. Complementary dominant factors for awn suppression appear to be located on chromosomes IX and XVII. These results are discussed in the light of recent comparable monosomic studies.
