Determination of Combining Ability and Heredity Through Diallel Analysis Method in F2 Populations of Cowpea

Cowpea is an essential economic crop in underdeveloped and developing countries mainly grown by small farmers. The parents F2 populations obtained for the F1 generation were planted, 3 rows of 2 m length, with row spacing 45 cm, 10 cm ecological conditions Konya 2021. 20 5 evaluated 2021 season. General combining ability (GCA) effects various differed significantly. “Sırma” gave significant, positive GCA number pod per plant, seeds seed yield plant protein plant. Significant, specific (SCA) smaller less significant than effects. non-additive dominant gene effect was determined all traits. Heterosis over high-parent observed five populations. In terms yield, best parent “Sırma”. heterosis a hybrids resulted from increased hundred weight. These results suggest that high yielding cowpea can be developed may contain acceptable levels superior agronomic technological characteristics.
