Abstract:

The present investigation was undertaken to study the extent of genetic variability, heritability (b.s.), genetic advance, genotypic and phenotypic coefficient of variation, correlation, path analysis, genetic divergence among thirty genotypes of soybean. These genotypes were evaluated during Kharif, 2018 in a randomized block design with three replications. Observations were recorded on days to 50 percent flowering, days to maturity, plant height (cm), number of primary branches per plant, number of pods per plant, number of seeds per pod, 100 seed weight (g), seed yield per plant (g), SPAD value, protein content (%), oil content (%). The treatment differences were statistically significant for all the characters. The phenotypic coefficient of variation (PCV) was found to be marginally higher than the genotypic coefficient of variation (GCV) for all the characters, indicating the dominance of the genotypic coefficient of variation for expression of these traits. Number of seed yield per plant exhibited the high GCV as well as PCV followed Number of pods per plant, plant height, number of seeds per pod, and 100 seed weight. The oil content exhibited the least GCV and PCV. Maximum heritability observed for the number of pods per plant (94.96), followed by plant height (93.11) and days to 50 percent flowering (91.38). The highest genetic advance estimates for the number of pods per plant, followed by plant height and days to maturity. The highest genetic advance as a percentage of mean was observed seed yield per plant followed by the number of pods per plant and plant height.
