Grain discoloration development is becoming a major threat to rice crop. Molecular diversity among 39 genotypes was assessed using 19 SSRs primers. The average PIC value 0.619 was determined among the genotypes along with all twelve chromosomes. Six parents were selected on the basis of disease incidence/severity i.e. CB-19, CB-42, Basmati-370, Basmati-515, IR-64 and Rondo. Half diallel analyses were conducted among the genotypes to study the heterosis on the basis of agromorphological traits.
