The phenotypic performance, heritability and selection response of quantitative traits vary due to genotypic differences, environmental factors and genotype by environment interaction. The present investigation was conducted with 36 greengram genotypes under three varying environments. Results of study indicated the significant differences among genotypes for almost all the traits studied under different environments. This study also revealed that heritability is affected by the environment. Some important traits viz., plant height, number of primary branches per plant, number of secondary branches per plant, pod mass, seed mass, biological yield per plant, harvest index and seed yield per plant showed low environmental influence comprising high heritability coupled with high proportion of selection response. Due to preponderance of additive gene action simple plant selection may be rewarding to improve yield and yield components.
