The study was conducted to assess the variation, genotypic and phenotypic coefficients of variation and estimate broad sense heritability and genetic advancement as percentage of the mean for seventeen traits in 18 genotypes of pearl millet (Pennisetum glaucum L. R. Br.). The experiment was carried out in a randomized complete block design with four replications at four sites in 2006 cropping season. Analyses of variance revealed significant differences among genotypes for all traits studied except plant population/ha. The highest genetic coefficients of variation were detected for grain yield (31.44%), harvest index (30.96%), dry panicle weight (28.56%) and grain yield per plant (25.83%). The highest phenotypic coefficients of variation were shown by grain yield  (38.07%), harvest index (37.89%)  and grain yield /plant (35.03%). The values of phenotypic coefficient of variation were higher than their corresponding genotypic coefficient of variation for all studied. High heritability estimates were observed for threshing percentage (0.75), days to 50% flowering (0.74), days to 95% maturity (0.73) and dry panicles weight (0.73). The predicted genetic advancement as percentage of mean was found to be very high for grain yield) (53.47%), harvest index (52.2%) and dry panicle weight (50.13%).


Keywords: Pearl millet, genotypic coefficient of variation, phenotypic coefficient of variation, heritability, genetic advancement, variations.
