Abstract

The present experiment was conducted with an aim to understand genetic variability and heritability among 30 soybean genotypes of different geographical locations during Kharif 2019 at TCA, Dholi, Bihar in Randomized Complete Block Design accommodating 30 genotypes randomly in three replicates. These genotypes evaluated for twenty-seven traits: five phenological, nine agro-morphological, eight physiological traits (from field trial) and five physiological traits from laboratory experiment recorded and subjected to statistical and biometrical analyses. Considerable variability was observed for these traits which revealed usefulness of existing genetic variability for all 27 attributes amongst which vigour index II, seedling dry weight, specific leaf weight and 100- seed weight was trust worthy (GCV in close correspondence with PCV; high h2bs & high GAM reflecting additive gene action) for selection criteria.
