Abstract:

The present investigation was conducted to evaluate the genetic divergence among forty pearl millet germplasm using Mahalanobis D2 statistics for thirteen different traits under rainfed condition for five years pooled data. Analysis of variance indicated considerable diversity among genotypes showing significant variability for all the characters. D2 clustering grouped the genotypes into eleven clusters. Based on cluster means, cluster II was suitable for early flowering and early maturity and cluster IV had highest grain yield per plant. The selection and choice of parents mainly depends upon contribution of characters towards divergence. The maximum contribution to genetic divergence was exhibited by number of productive tillers per followed by single plant yield, days to maturity, plant days to fifty per cent flowering, spike length, plant height, harvest index, test weight spike girth, reproductive period, ear exertion distance, stover yield and number of leaves per plant. Hence selection for these characters may be useful.
