| Abstract | ||||
| The combining ability and heterosis have been analyzed in a 7-parents F1 diallel cross for yield and its components. The experiment was conducted at the Experimental Farm., Faculty of Agricultural, Assiut University. The analysis of variance indicated highly significant differences among the 28 entries for days to 50% flowering, plant height, first fruiting node on the main stem, number of branches/plant, number of seeds/pod, number of pods/plant, 100 seed weight and seed yield/plant. Variances due to general combing ability as well as specific combing ability were highly significant for the above-mentioned traits. However, the ratio of the genetic components; was less than unity of the non-additive genetic variance in the inheritance of all the above traits except days to 50% flowering. The analysis of variances and covariance of arrays indicated epistatic effect of complementary type in the inheritance of first fruiting node, and non-allelic interaction of duplicate type for number of branches/plant, number of seeds/pod, 100 seed weight and seed yield/plant. Hertotic effects over mid and better parents were shown in F1 hybrids for all studied characters. | ||||
