Abstract:

The current experimentation was carried out at the field experimentation centre, Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, U.P. Thirty two genotypes which include, 29 advanced breeding lines and three checks, were examined for several genetic parameters and genetic divergence among them using D2 statistics for 13 quantitative characters. The analysis divided the 32 genotypes into seven clusters based on Tocher’s clustering method. Out of the seven clusters formed, cluster I was the largest with eight genotypes and cluster VI and VII were monogenotypic. Highest inter cluster distance was found between cluster II and cluster IV indicating higher diversity between the genotypes of those clusters. Cluster II had highest mean for test weight character and cluster IV had highest mean for number of tillers per hill, number of panicles per hill and number of spikelets per panicle. Hence, hybridization between genotypes of these clusters would yield transgressive segregants. Highest intra-cluster distance was recorded in cluster V. Test weight had the highest heritability and maximum contribution towards divergence where as number of panicles per hill, flag leaf width, number of spikelets per panicle, biological yield and grain yield per hill had no contribution towards divergence.
