| Abstract | ||
| The present investigation was carried out during 2013/2014, 2014/2015 and 2015/2016 successive seasons, at Experimental Farm Faculty of Agriculture (Assiut Branch) Al-Azhar University. The obtained results showed that the expected response to selection was lower than the actual response to selection for the studied traits in respect to the two selection criteria number of pods/plant and seed yield/plant. The results showed that the average plants recorded lower values in F3 generation and increased gradually in the next generation for the studied traits except, average for days to maturity which recorded higher values in F3 generation and decreased gradually in the next generation for the two selection criteria. In plant height (cm), number of pods/plant, seed index (100-seed weight gm.) and seed yield/plant (gm) the average of the bulk populations was less than those for selected families in F3, F4 and F5 generations, except, for number of days to maturity where in the bulk populations was higher than selected families in F3, F4 and F5 generations for the two selection criteria. Phenotypic and genotypic coefficients of variability recorded higher values in F3 generation and decreased gradually in the next generation for the studied traits. Positive and significant phenotypic and genotypic correlation coefficients were recorded between seed yield per plant and all the studied traits, except days to maturity it was negative and significant for the two selection criteria. Heritability in narrow sense was high (<50%) for plant height and 100-seed weight in F4 and F5 and varied from low to moderate for the remaining traits. | ||
