SSR markers associated with seed longevity in soybean
The objective of this research was to identify SSR markers associated with seed longevity in an F2:3 soybean population of a cross of Birsa soya-1 x JS 71-05. The parental polymorphism survey was carried out using 145 SSR markers, of which 21 were polymorphic. These markers were used for genotypic analysis of 153 F2 individuals. To assess the longevity, seeds of 153 F2:3 lines collected from the replicated trails at two locations were subjected to accelerated aging test in laboratory. A total of four (Satt538, Satt285, Satt600 and Satt434) independent SSR markers were significantly associated with seed longevity. Individually these markers explained between 6.3 % (Satt285) and 7.5% (Satt434) of the total phenotypic variation for the trait. This is the first report on the use of SSR markers for identifying quantitative trait loci for seed longevity in soybean.
