Seed longevity studies in wild type, cultivated and inter-specific recombinant inbred lines (RILs) of soybean [Glycine max (L.) Merr.]

Loss of seed viability is a serious hurdle in production and ambient storage soybean. Understanding the factors affecting viability, identification soybean genotype(s) with higher critical for production. In this study, seeds 125 genotypes three different species [Glycine tomentella Hayata, Glycine max subsp. soja (Siebold & Zucc.) H. Ohashi, max(L.) Merr.] 25 RILs (Glycine × max) were tested germination immediately after harvest followed by 1, 2 3 years storage. Fresh all recorded 78–99% mean 94.02%. However, value per cent decreased found to stand at 79.51%, 52.24% 29.18%, respectively. Among tested, G. accession registered highest storability soja, max. After storage, 14 wild type maintain > 70% and, identified as ‘good storers’. Genetic divergence studies via k-mean clustering principal component analysis grouped clusters. Seed was significantly negatively correlated electrical conductivity. Good storers be having slow imbibition rate than poor initial hours imbibition. The good storing study will serve an elite genetic resource developing cultivars better longevity.
