Abstract Green gram is the third most important pulse crop of the country in combination with cereals, forms a complete meal with high biological value. The presence of useful genetic variability in the breeding material coupled with resistance to major biotic and abiotic stresses is essential. With this background, genetic variability for yield and its attributing characters was assessed in F4 and F5 progenies of five different crosses viz., BL-865 × Chinamung, LM-192 × MDU-3465, BL-865 × SML-348, LM-192 × SML-348 at UAS, GKVK, Bengaluru during Kharif and Rabi 2016. Observations were recorded on seed yield and its attributes. Data was also recorded on reaction to stress. The results indicated significant difference among the families for all the characters in F4 and F5 generations. Moderate to high PCV and GCV for the traits studied indicated higher magnitude of genetic variability among the families and narrow difference between them indicated lower environmental influence except for days to 50 per cent flowering and pod length. High heritability coupled with high GAM was recorded in both the generations indicating the prevalence of additive gene action and usefulness of selection to improve the traits. The positive association of plant height, primary branches plant-1, clusters plant1, pod yield plant-1 with seed yield-1 and positive direct effects of pod yield plant-1, pods plant-1 and indirect effect of plant height, primary branches plant-1, clusters plant-1 on seed yield plant-1 was noticed. The best families were selected based on powdery mildew resistance coupled with high yield from F5 generation.
