Abstract:
Reciprocal crosses were carried out between Triticum dicoccoides sel. G-25-highly resistant to Puccinia striiformis race 20A-and Triticum durum cultivar Nursith 163-which served as susceptible parent. F1 hybrids in one of the crosses showed a wide range of infection types to the test isolate, whereas in a repeated cross all F1 plants proved highly resistant. The variable reaction pattern observed in the F1 hybrids of the first cross suggests incomplete penetrance of the resistance factor in certain environmental conditions. The segregation ratio displayed by the F2 progenies indicates that a single dominant factor for resistance to stripe rust race 20A was transferred from wild emmer to cultivated durum wheat. © 1974 H.
