The 52 germplasm lines of pearl millet (Pennisetum glaucum L.) were evaluated for eight quantitative characters with a view to study the genetic variability, correlation and path analysis. The High values of GCV, PCV and heritability estimates coupled with maximum genetic advance over mean were obtained for the characters like productive tillers per plant, grain yield per plant, seed weight, seed yield per ear head and panicle length traits. The results of correlation and path analysis revealed that grain yield per plant exhibited positive significant correlation with panicle length and panicle girth. The plant height, panicle girth and panicle length traits contributed the highest positive direct effect on grain yield.
