“…In general the phenotypic and genotypic correlation estimates followed almost similar trend. The characters number of seeds per pod, number of pods per plant and number of clusters per plant showed high positive correlation among themselves both at genotypic and phenotypic level which is in close agreement with the report of Kanimoli et al, (2018) and Pavan et al, (2019). Number of primary branches per plant showed moderate but significant positive association with plant height, and plant height with number of pods per plant and harvest index.…”

Genetic variability, heritability along with genetic advance of traits, their association and direct and indirect effects on yield are essential for crop improvement. One hundred and three greengram genotypes were studied to assess variability and degree to which various plant traits associate with seed yield. Sufficient genetic variability was observed for plant height, pods per plant and seed yield. Number of primary branches per plant, number of clusters per plant and pod length showed lesser variability while 100 seed weight and harvest index exhibited intermediate range of variability. Moderate to high heritability estimates were found for all traits. Number of primary branches per plant, pod length and 100-seed weight exhibited negative and non significant genotypic and phenotypic correlations with seed yield. Plant height showed positive non-significant genotypic and significant phenotypic correlation. Number of clusters per plant, number of pods per plant and harvest index showed positive significant genotypic and phenotypic correlations with seed yield. Positive direct effects were exerted through number of pods per plant, pod length, 100 seed weight and harvest index while number of primary branches per plant, plant height and number of clusters per plant had negative direct effects. The present findings could be useful for establishing selection criteria for high seed yield in the greengram breeding.
