The present investigation was carried out to study the genetic variability parameters and character association in fifty pearl millet genotypes for thirteen different biometrical traits. A wide range was observed for all parameters of genetic variability for all the traits. The traits like grain yield, seed weight per spike, number of productive tillers, flag leaf area, number of nodes per plant showed greatest variability and considered highly variable compared to other biometrical traits. Character association studies revealed that grain yield was highly significant and positively correlated with seed weight per spike (0.70), spike length (0.69), 1000 grain weight (0.56), number of productive tillers (0.53), number of tillers per plant (0.49) and peduncle length (0.42). Highest direct effect on grain yield was contributed by the number of productive tillers per plant and seed weight per spike. Number of nodes per plant and number of tillers per plant showed high positive and indirect effect on grain yield through number of productive tillers. Hence, these traits were regarded as significant attributes in devising selection criteria for attaining yield objectives.
