Abstract: Significant genetic variability was observed among 13th aromatic short grain genotypes include two elite lines and one local check of rice for yield and quality parameters indicating that there is presence of sufficient amount of variability in the study material and there is scope of selection. The genotype CN1646-6-11-9 found best for mean performance of grain earliest yield, its component and quality traits except HRR% and gel consistency which was statistically at par with highest yielder genotype Pant Dhan-4(check). High heritability coupled with high genetic advance were recorded for number of spikelets per panicle, L/B ratio, volume expansion ratio and gel consistency indicated the major role of additive gene action in the inheritance of these character and these character could be improved by selection in segregation generation. Thus parameter during breeding programme for crop improvement

Keywords: aromatic rice, genetic variability, heritability, genetic advance, grain physical quality, grain cooking quality.
