Genetic divergence studies for yeild and its components in rice (oryza sativa l.) accession
Author(s): Krishna Tandekar, Sandeep Bhandarkar and AK Sarawgi
Abstract: The hundred genotypes of rice accession were used to study the nature and magnitude of genetic divergence Mahalonobis D2 statistics. The genotypes were grouped in to 10 cluster showing fair degree of relationship between agro-morphological variation and genetic divergence. The higher inter cluster distance was in between cluster II and cluster V followed by cluster VII and cluster I, cluster IX and cluster II and cluster III and cluster II. The lowest inter cluster distance was found between cluster III and cluster I. Thus, in the present study the better genotype were identified in respect to most of the characters on the basis of mean performance in the cluster. The inter cluster distances in the present study were higher than the intra cluster distances in all cases reflecting wider diversity among the genotypes of the distant group. The best genotypes in the present study for seed yield per plant are Veerhuli, Jaldubi and Lohandi and for harvest index the superior genotype are Kaveri, Kansari and I.T.
