摘要

Six wheat genotypes with wide genetic variability for resistance to X. campestris pv. cerealis [X. translucens pv. cerealis] were crossed in diallel fashion to determine the inheritance of resistance. Parental genotypes and their F1 hybrids were inoculated at the second leaf stage with an Iranian isolate. The genotypes IBPT66, IBPT84 and IBPT34 had a high level of partial resistance to the disease. General and specific combining abilities presented several significant positive or negative values suggesting the importance of additive and dominant genetic control for partial resistance to this bacteria. It is concluded that the resistant line IBPT66 could be a donor of partial resistance to bacterial leaf streak in wheat.
