Validation of hybrid rice seed vigour traits using SSR marker (Oryza sativa L.)

Published on Jul 31, 2020 05:46 AM

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.
