In this experiment hybrid combination of whole set of ⊙6 translocation heterozygotes were grown in the field to investigate the effects of chromosomal translocation on the yield components. Ther results showed that:100-Seed weight as well as ear weight, were the most important factor on grain yield. Ear fertility was inferior to 100-seed weight and ear weights owing to the low fertility (25%) of the ⊙6 individuals. Vegetative characters such as silking date and plant height, had less influences on yield. The influence of plant height appeared only when the effects of 100-seed weight and fertility were omitted. However, silking date showed no effect on grain yield if 100-seed weight and fertility were omitted. |
