Genetic Parameters Studies in Aromatic Rice

The present investigation consists of 38 rice genotypes and the experiment was conducted during Kharif-2015 in Randomized Block Design with three replications. The data were recorded for 11 quantitative characters to study genetic variability, heritability and genetic advance. On the basis of mean performance, high grain yield per plant were exhibited by the genotype Pusa-1460. Analysis of variance among 38 genotypes showed significant difference for all characters studied. Highest genotypic coefficient of variation (GCV) & phenotypic coefficient variation (PCV) was observed for grain yield per plant followed by biological yield per plant, panicle length, number of grain per panicle, harvest index, test weight and number of productive tillers per plant indicating that these characters could be used as selection for crop improvement. On the basis of high estimates of heritability coupled with high genetic advance was observed for plant height, number of productive tillers per plant, panicle length, biological yield per plant, harvest index, test weight and number of grains per panicle indicating predominance of additive gene effects and possibilities of effective selection for the improvement of these characters.
