Description An interspecific derivative 'Selection T2836- 1 ' of wheat (Triticum aestivtm emend. Fiori & Paol.) was tested with 3 stem rust pathotypes, namely 62629 (40A); 62029- 1 (40- 1) and 13761 9 (1 17-6). The study on mode of inheritance revealed that the resistance to 62629 and 137619 pathotypes was controlled by a single dominant gene, while single recessive gene governed resistance against 62629-1 pathotype. Result of test of allelism with stem lust resistance genes Sr24 and Sr25 indicated that the resistance present in 'Selection T2836-1' is diverse than that conferred by Sr24 and Sr25. The genetic analysis revealed that clubbed ear shape is controlled by 2 dominant complementary genes. The identification of diverse resistant source may be useful in breeding and the determinatian oi genetic control of club ear shape may be an useful marker in genetic analysis.
