| Abstract | ||||
| The Present investigation was carried out at Sakha Agric. Res . Sta. from 1996/97 to 1998/1999 seasons to study the inheritance of wheat resistance to stripe rust caused by Puccinia Striiformis tritici at adult stage , under field conditions on quantitative basis . Moreover the results of the six populations ; P1, P2, F1, F2, Bc1 and Bc2 for the three crosses ; Sids 8 x Sakha 61, Sids 8 x Vee # 5 “s” / Bow “s” and Sids 8 x Kinglet proved that heritability values in broad and narrow senses were high in cross 1 (58.26 and 82.32%) and cross 3 (80.6 and 78.04 %) where these values for cross 2 were 70.26 and 62.61 % , respectively. The obtained results revealed that degrees of dominance for the F1 (h1) were –0.91, -0.71 and 0.80 while they were –0.68 , -2.08 and –1.71 for the F2 (h2) in the three crosses, respectively , indicating partial dominance for resistance in both F1 and F2 populations in all crosses . | ||||
