ABSTRACT

Thirteen indigenous aromatic rice cultivars were studied during July to December 2018 to find out the variability and genetic parameters for grain yield and its component characters. There is significant variation among the genotypes for the tested characters. The high genetic variability was obtained for no. of filled grain per panicle. Phenotypic variances were higher than genotypic variance for the tested characters. The highest genotypic co-efficient of variation was observed for harvest index followed by grain yield, no. of filled grain per panicle, thousand grain weight and no. of plant per hill. High heritability were coupled with high genetic advance in percent of mean in case of thousand grain weight, plant height, no. of filled grain per panicle, panicle length, harvest index and grain yield signifying greater scope for selection for these traits.
