ABSTRACT
An experiment was conducted to evaluation of genetic variability present in the forty one genotypes and five checks (two local + three national checks) and observations were recorded on various yield and yield contributing characters viz., days to 50% flowering, days to maturity, plant height, number of branches per plant, number of pods per plant, 100 seed weight, harvest index and grain yield per plant at field level and oil content, protein content and trypsin inhibitor content in the laboratory. Analysis of variance showed the significant variability for all the studied characters. High values of GCV and PCV were observed for charactersviz., number of pods per plant (35.45, 38.62), plant height (23.49, 25.84), yield per plant (21.35, 24.86) and number of branches per plant (20.58, 24.22) which indicates the presence of high genetic variation. High heritability coupled with high genetic advance observed for the traits viz., Pods per plant, plant height, yield per plant, branches per plant, trypsin inhibitor content and 100 seed weight which indicates presence of additive gene action and demands for population improvement by selection.
Key words: Genetic variability, Heritability, Genetic advance, Soybean, GCV, PCV
