The present investigation consists of 20 genotypes of greengram, which were grown in the Field Experimentation
Centre of the Department of Genetics and Plant Breeding, SHUATS, Prayagraj during Kharif,2019, following RBD
with three replications. The data was collected on 11 characters in order to investigate genetic variation and character
association. IC-314674, followed by BM-2002-1, and PM-6, were recognised as desirable genotypes for seed yield per
plant based on mean performance. Seed yield per plant and harvest index both had high GCV. Harvest index and
quantity of pods per plant both showed high PCV. Seed yield per plant and pod length had high heritability estimates,
while a number of clusters per plant, plant height, harvest index, number of pods per plant, biol ogical yield, days to
50% flowering, and number of seeds per pod had moderate heritability. The number of primary branches and seed
index had low heritability. Traits having a high heritability and a high genetic advance as a percentage of the mean
are thought to be regulated by additive gene action, with equal contributions from additive and non-additive gene
activity. Harvest index, seed index, number of clusters per plant, and number of pods per plant all exhibited a highly
significant positive relationship with seed yield per plant. Days to 50% flowering, number of major branches per plant,
number of clusters per plant, and number of pods per plant all had positive direct effects on grain output. As a result,
these features could be employed as a viable selection indicator for greengram yield improvement by selective
breeding.
