Abstract:
Sixteen genotypes of Sorghum [Sorghum bicolor (L.) Moench] were evaluated in a Randomized Block Design with three replications at NEBCRC, GBPUA and T, Pantnagar, Uttarakhand. The objective of preent study was to measure the genetic divergence for yield and yield related components by using Mahalanobis D² method. The observations were recorded for 13 different traits and results revealed that seven different clusters were obtained. The cluster I was largest and contained the maximum number of genotypes i.e 9 followed by cluster IV (2) while the cluster II, cluster III, cluster V, cluster VI and cluster VII each contained one genotype, respectively. Highest inter cluster distance was recorded between cluster IV and V (26.37). The higher inter cluster distance as compared to intra cluster distance suggested the presence of sufficient amount of genetic divergence among genotypes under studied. Maximum inter-cluster distance was obtained between cluster V and IV, which indicated that the genotypes belonging to these clusters could be used as parental material under a hybridization programme for getting desirable/transgressive segregants. The characters green fodder yield per plant, plant height, protein and TSS was found as major contributing characters towards the genetic divergence.
