Abstract
A set of 140 recombinant inbred lines (RIL’s) population (F8) derived from interspecific cross C. arietinum cv K 850 X C. reticulatum (ICCW 8), were studied for the various genetic parameters viz., magnitude of genotypic and phenotypic variation, heritability, genetic advance and correlation coefficients. Maximum variability was observed for yield/plant followed by number of pods/plant and 100- seed weight. Maximum heritability was observed for seed weight (92.5%) followed by seeds/pod (74.5%) and plant height (59.8%). High expected genetic advance coupled with high heritability estimates were observed for yield/ plant, pods/plant and plant height suggesting a possibility of isolation of superior lines for these characters in recombinant inbred population. Yield /plant had significant positive phenotypic and genotypic correlation with 100- seed weight, seeds/pod and pods/plant. Based on mean performance of RILs over control, superior lines were selected for various yield component traits.
