Abstract:

The objective of this research was to identify SSR markers associated with seed longevity in an F_2:3 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 F_2:3 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.
