| Abstract | ||||
| Seeds of the pea cultivar Master B were irradiated with different doses of gamma-rays (0, 2.5, 5, 10, 15, 20, 25 and 30 KR), another portions of the seeds were treated with different levels of EMS (0.0, 0.025, 0.05, 0.1 %). Also, there were combined treatments using the two mutagenic agents. The results of this investigation showed that the M2-plants exhibited different degrees of reduction in growth in comparison with those of the untreated control plants. In M2, the mutagenic doses significantly increased the mean value for plant height, number of pods per plant and seed yield per plant. However, the results did not show additional variation for number of branches per plant and number of seeds. per pod. In M2-generation, 107 different mutant lines were selected. | ||||
