Forty accessions of pearl millet were evaluated for five consecutive years (environments) to assess the magnitude of presence of genetic variability, heritability in broad sense, genetic advance, inter characters correlation and path coefficients for yield and yield contributing characters. All the accessions showed considerable amount of variation in their mean performance with respect to studied characters. The phenotypic co-efficient of variation (PCV) was greater than genotypic co-efficient of variation (GCV) for all the studied characters this shows the influence of environmental factors on the expression of characters. High GCV and PCV estimates were observed for plant height, total number of tillers per plant, number of productive tillers per plant, number of leaves per plant, spike girth, ear exertion distance, test weight, and yield per plant in all the environments. High heritability coupled with high genetic advance was observed for plant height, total number of tiller per plant, number of productive tillers per plant, number of leaves per plant, spike length, spike girth, ear exertion distance, test weight, yield per plant, stover yield per plant and harvest index in all the environments. Seed yield per plant was positively and significantly correlated with number of productive tillers per plant, number of leaves per plant, spike length, spike girth, test weight, stover yield and harvest index in all the environments and in pooled environment. Genotypic path coefficient analysis revealed highest positive direct effect registered by spike girth, spike length, number of productive tillers per plant, plant height and test weight in all the environments. Hence, these characters have to be given importance during the selection programme to improve the seed yield potential of the crop.
