Abstract

Seed vigour is an important characteristic of seed quality. Several quantitative trait locus (QTL) has been reported for seed vigour in many crops. In order to validate seed vigour traits, an experiment was conducted with three released rice hybrids and their respective female (A), and restorer/ male lines using SSR markers. A total of 18 quantitative traits loci (QTLs) were chosen for seed vigour characters for which 16 SSR markers that were dispersed throughout the 11 chromosomes of rice have been assessed. Eight SSR markers were polymorphic among the genotypes studied. These markers showed distinct bands in female (A), male (R) and hybrid (H). Further, genuineness of all the hybrids under study could be established using the primer RM 252.
