Variability and character association for yield attributes and several grain quality characters were studied in twenty-six aromatic rice genotypes. Yield per plant had high coefficient of variation at both the genotypic (GCV) and phenotypic (PCV) level. Highest GCV value was noted in number of grains per panicle. Test grain weight plant height, length and length-width ratio of kernel and kernel length after cooking had moderate to high GCV and PCV values. Heritability estimates in broad sense was moderate to high for all the characters studied. Yield per plant, test grain weight, plant height number of grains per panicle, length-width ratio of kernel, kernel length afte cooking and amylose content had high genetic gain as percent of population mean. Yield per plant had a very strong genotypic correlation with test grain weight. The later, however, was positively correlated with test grain weight. The later, however, was positively correlated with kernel length but was negatively correlated between them. Elongation ratio had very strong positive correlation with kernel length and test grain weight a both the genotypic and phenotypic level. Amylose content was positively correlated with kernel length and test grain weight at both levels.
