Abstract: For effective trait selection, it is very important to have knowledge of association between traits and heritability. So, a study on phenotypic diversity in pearl millet [Pennisetum glaucum (L.) R. Br.] was intended in a set of 48 maintainer lines using 9 quantitative traits. Significant mean sum of squares indicated presence of sufficient variation in the lines. The GCV were slightly lower than PCV indicating the slight influence of environment on the expression of characters. Number of productive tillers/plant, plant height, 1000 grain weight, grain yield/plant had high heritability with high genetic advance as% of mean suggesting the prevalence of additive gene action in their inheritance which suggest that selection will be more effective based on these traits. Correlation coefficient analysis revealed that days to 50% flowering, spike length, number of productive tillers per plant, 1000 grain weight, dry and green fodder yield were significantly and positively correlated with grain yield per plant. The traits, days to 50% flowering, spike length, number of productive tillers/plant had high significant direct contribution towards grain yield/plant for which indirect selection can be made in future breeding programme to enhance grain yield.
