Abstract

Seven fine rice genotypes including three aromatic hybrids were evaluated for fifteen quantitative characters to select the most yield enhancing characters as well as the diverged cultivars for hybridization. The mean performances and genetic parameters of the characters were separated through univariate analysis; the most yield promoting characters were selected by bivariate and multivariate analyses and desirable parents were selected by univariate and multivariate analyses. Though high heritability was estimated for most the characters but the highest genetic advance was estimated against total grain/penicle(112.4). Productive tillers/plant, thousand grain wt., days to 50% flowering and days to maturity showed positive and significant, and plant height showed negative and significant correlation coefficients with yield. Upon partitioning the total phenotypic correlation coefficients with yield, 1000-grain weight exerted the highest direct effect (1.05) therefore;these characters appeared as the predominant yield accelerating characters in fine rice. It was initially aimed to develop experimental hybrids through a diallel model. The three hybrids were evaluated and their competence was measured by two criteria of heterosis. The aroma contents in the hybrids and their parents were compared. Out of three hybrids, there were in which the highest aroma was assessed in the F1of Kataribhog ×Begunbichi, hence consideration of yield and aroma content these hybrids may bring to obtain desirable aeromatic rice.
