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 agro-morphological
traits. Some hybrids had good heterosis for specific traits such as productive tillers per plant (IR-64 × Bas-370), seeds per
panicle (IR-64 × Rondo) and 1000 grain weight (Bas-515 × Rondo) can be used for the production and development of new
plant population especially controlling the new emerging rice grain discoloration disease.
