The analysis of inter-relationship among different characters in 76 genotypes of pearl millet (Pennisetum glaucum (L.) R. Br.) showed that the grain yield possessed a high and positive association with number of productive tillers, plant height, and 1000 grain weight. The characters, plant height, days to 50% flowering and ear length were mutually correlated. The character pairs, ear length and ear thickness; and 1000 grain weight and number of productive tillers were positively correlated with each other. The path coefficient analysis revealed that number of productive tillers and plant height had both direct and indirect effects to account for yield. The character thousand grain weight which had positive correlation with yield, showed negative direct effect but had indirect effect through plant height, number of productive tillers, ear length and ear thickness.
