Winter wheat cultivars Aquileja (AQ) and Xian Nong 4(XN) were previously reported to possess durable, quantitative resistance to stripe rust disease. In the present study, AQ, XN and a susceptible wheat cultivar were reciprocally crossed in all 6 combinations. Parents, F1, F2, F3, BCP1 and BCP2 were used to determine quantitative genetic parameters for infection type and disease severity. The results showed that fixable genetic components preponderated in the inheritance of the resistance in AQ and XN for both infection type and disease severity, while the dominant component could be detected in some cases. The resistance was conditioned by oligogenes. Heritability of the resistance ranged from 50 to 79% in most cases.
