A set of 24 genotypes were studied for 17 grain quality characters and validated with the reported associated rice microsatellite markers with grain quality characters. Using 23 polymorphic markers distributed across 11 chromosomes marker-trait associations were studied. The percentage of polymorphism information content (PIC) of the markers ranged between 54.0 and 86.7. Eight markers with80% and seven markers with70% of PIC were found to be efficient in differentiating the studied grain quality characters. A total of 37 significant marker-trait associations (P ≤ 0.09) were found with
