| Popis: | Six wheat genotypes with wide genetic variability for resistance to bacterial leaf streak were crossed in diallel fashion to determine the inheritance of resistance to this disease. Parental genotypes and their F1 hybrids were inoculated at the second leaf stage with an Iranian isolate of Xanthomonas campestris pv. cerealis. Two experiments were undertaken in a controlled environment chamber. Results showed that 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, showing the importance of both additive and dominant genetic control for partial resistance to this bacterial disease. The resistant line IBPT66 could be a good donor of partial resistance to bacterial leaf streak in wheat. |
