Background: Knowledge about the relationship between yield and the yield contributing characters can help breeders to effectively select for the characters that can efficiently increase yield. The present investigation studies correlation and path coefficient analysis in soybean. Methods: 30 genotypes of soybean were obtained from Agriculture Research Station (ARS), Kasbe Digraj, Sangli and sown in a randomised block design with three replications. Eleven characters were observed viz., days to 50% flowering, nodulation count per plant at 50% flowering, days to maturity, plant height, branches per plant, pods per plant, 100 seed weight, pod blight incidence, seed yield per plant, protein and oil content. Result: The correlation analysis revealed that seed yield per plant showed highly significant positive correlation with pods per plant (0.8471), followed by 100 seed weight (0.4087) and branches per plant (0.2836). The characters protein content (-0.1600) and days to maturity (-0.1566) showed negative and non-significant association with seed yield per plant. Path coefficient analysis showed that the characters pods per plant (0.8612), 100 seed weight (0.2476) and days to 50% flowering (0.2333) had high to moderate positive direct effect on seed yield per plant. Days to maturity (-0.0758) had negative direct effect on seed yield per plant. [ABSTRACT FROM AUTHOR] |
