Character association for seed yield and seed longevity in soybean

Abstract

The extent of genetic variability and correlation for yield and seed quality traits in 24 genotypes of soybean was evaluated during rainy 2014. Wide genetic variability with high heritability and genetic advance was observed for seedling dry weight, SVI II, Seed Yield/ha and clusters/plant indicating additive gene action with further scope to enrich variation for these characters. The seed yield/ha has shown significant positive correlation with days to 50% flowering, plant height, clusters/plant, pods/plant and 100 seed weight. SVI I has shown positive association with 100 seed weight, germination %, seedling length and seedling dry weight while SVI II for 100 seed weight, germination %, Seedling dry weight and SVI I. genotypes GP 13, Basar, A-3-1 and RKS 18 have shown superior performance in terms of seed longevity and seed yield.
