| Abstract | ||||
| The F4 and F5 population of twenty Chickpea (Cicer arietinum L .. ) crosses made between seven local and exotic genotypes were used in this study. Genotypic and phenotypic coefficients of variation, and also heritability and expected genetic gain were estimated for plant height (em.), height of first pod (em.), number of branches, pods, seeds I plant, seed weight I plant, seed yield ton I fed. , number of seeds I pod , days to 50 % flowering, days to maturity and wilt disease infection %. Both coefficient of variation were high for all characters except number of seeds I pod in F5 generation. The phenotypic coefficient of variation was greater than Genotypic or environmental coefficient of variation for all characters in both F. and Fs generations. It is therefor suggested that these characters could be used as selection criteria for further improvement of Chickpea. High heritability coupled with high genetic advance observed for plant height, height of first pod , number of pods , seeds I plant , seed yield ton I fed. , 100 seed weight. days to 50 % flowering and wilt disease infection % in F. generation , number of pods, seeds I plant, seed weight I plant, seed yield ton I fed., 100 seed weigttt , days to 50 % flowering and wilt disease infection % in Fs generation. | ||||
