The present investigation was carried out at Student’s Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur- 2080 02 (U.P.) during 2020-23. This area falls in sub-tropical climatic zone. The soil type is sandy loam. The annual rainfall is about 1270 mm. The climate of district Kanpur is semi-arid with hot summer and cold winter. Geographically, Kanpur is located at an altitude of 127 meters above the mean sea level and the latitude and longitude with 26.400 N and 80.100 E respectively. The increase under selection may typically be predicted more accurately with the combination of heritability estimates and genetic advancement than with heritability estimates only. In this study, heritability was reported for days to maturity (23.1%), days to 50 % flowering (21.8%), harvest index (21.5%), no. of pods per plant (21.0%) and pod length (20.4%) in F1 generation. Heritability was reported for days to maturity (20.9%), days to 50% flowering (20.5%), number of pods per plant (20.2%), protein content (18.6%) and harvest index (14.0%) in F2 generation. High genetic advance as percent of mean was recorded for number of branches per plant, number of pods per plant, harvest index in F1 generation while number of branches per plant, plant height and harvest index in F2 generation.

Heritability, Genetic advance, Green gram and Yield.

Number of branches per plant, number of pods per plant, harvest index and plant height shows low heritability accompanied with high genetic advance. Characters are determined by additive gene effects when low heritability is combined with strong genetic advancement. High environmental impacts are manifesting as poor heredity. In such circumstances, selection could be useful.
