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.

Adult plant resistance (APR) to wheat stem rust has been one of the approaches for resistance breeding since the evolution of the Ug99 race group and other races. This study was conducted to dissect and understand the genetic basis of APR to stem rust in spring wheat line ‘Copio’. A total of 176 recombinant inbred lines (RIL) from the cross of susceptible parent ‘Apav’ with Copio were phenotyped for stem rust resistance in six environments. Composite interval mapping (CIM) using 762 Genotyping-by-Sequencing (GBS) markers, identified 16 genomic regions conferring stem rust resistance. Assays with gene-linked molecular markers revealed that Copio carried known APR genes Sr2 and Lr46/Yr29/Sr58 in addition to the 2NS/2AS translocation that harbors race-specific genes Sr38, Lr37 and Yr17. Three QTL were mapped on chromosomes 2B, two QTL on chromosomes 3A, 3B, and 6A each, and one QTL on each of chromosomes 2A, 1B, 2D, 4B, 5D, 6D and 7A. The QTL QSr.umn.5D is potentially a new resistance gene and contributed to quantitative resistance in Copio. The RILs with allelic combinations of Sr2, Sr38, and Sr58 had 27-39% less stem rust coefficient of infection in all field environments compared to RILs with none of these genes and this gene combination was most effective in the US environments. We conclude that Copio carries several genes that provide both race-specific and non-race-specific resistance to diverse races of stem rust fungus and can be used by breeding programs in pyramiding other effective genes to develop durable resistance in wheat.
