| Abstract | ||||
| The F3, F. and Fs genotypes of twenty chickpea crosses were made by the International Center for Agriculture Research in the Dry Areas (ICARDA) . Two local varieties ( Giza 195 and giza 531) were used as checks in this study. Genetic variability , heritability in broad sense and genetic advance were estimated for genotypes in F3 , F. and Fs generations. Results revealed that genetic variance was existed and significant for most traits in F3, F4 and Fs generations. Environmental variation was notably high for yield and yield components ( number of pods, seeds, seed weight per plant and seed index) as well as seed yield ton I fed. which resulted in relatively moderate to low heritability and genetic gain values estimated for most characters in F3 , F 4 and F s generations. On the basis of the relatively high heritability , genetic coefficient of variation and expected genetic advance pronounced progress should be expected from selection for plant height ,height of first pod, number of pods • seeds and ,seed weight per plant and seed index, while moderate progress should be expected with number of branches / plant. number of seeds/pod, flowering , maturity date and wilt disease infection. | ||||
