Ten genotypes of Pearl millet identified from the germplasm (Pennisetum glaucum (L) R. Br. were grown in a complete randomized block design with three replicates and the yield and four other yield contributing characters were studied. The coefficient of genotypic, phenotypic and environmental correlations and heritability in broad sense were worked out to determine the degree of association among the agronomic characters. A good amount of genetic variability for different characters were observed. Heritability of 1000-seed weight and grain yield was highest, whereas the number of productive tillers had low heritability. Grain yield was positive and significantly correlated with the number of productive tillers, panicle width, panicle length and 1000-seed weight. Significant negative correlation was observed between the number of productive tillers and panicle width. There was a positive association between the number of productive tillers, panicle length and 1000-seed weight and grain yield High significant association also existed between panicle width and panicle length.
Key word: Correlation, heritability, pearl millet, genetic advance.
