Abstract:
Soybean [Glycine max (L.) Merill] cultivars varies in storability period at ambient storage. In this study, 11 cultivars of soybean varying in storability (good and poor), seed hardiness and seed testa colour (black and yellow) were characterized with 9 SSR markers. Polymorphisms detected by SSR markers were zero to 11%. Cultivars with black seed coat colour showed better storability than the yellow seed coated cultivars indicating possible association of black seed coat colour with good storability. Genetic similarity coefficients obtained through SSR data analysis in all the soybean cultivars. SSR markers SATT 453, SATT 618, SATT 400, SATT 143 and SATT 286 produced specific allelic bands making them candidate markers for linkage with seed storability and testa colour. SATT 184, SAT_170 had linkage with seed hardiness and SATT 162 and SATT 523 had linkage with seed testa colour. SSR markers data grouped the cultivars broadly into three major clusters that had no congruence with seed storability, seed hardiness and seed testa colour.
