Abstract
A study on the type of gene action from diallel analysis of six se‌same parents was done in 1990 and 1991. Data revealed that the WriVr regression coefficients were not significantly different from unity and significantly different from zero for plant height and number of branches / plant, which reflects the importance of additive gene action. Partial dominance was detected for plant height and number of branches. On the other hand, height of the first capsule, number of cap‌sules/plant, seed index, seed yield/plant and seed oil content exhibited over dominance. In all studied characters the results showed the importance of both additive (0) and dominance (H1) genetic ocmponents except for oil content. The dominance genetic variance (H1) was more important than the additive genetic variance (D) for first capsule, number of capsules/ plant, seed yield / plant, seed index and oil content. Meanwhile, the (D) was more important, for plant height and number of branches. Plant height had the highest heritability value either in broad sense or the narrow sense. Seed yield showed the lowest narrow sense heritability (9.34%).
