Genetic divergence studies among rice genotypes

Author(s):

Abstract:
This study aim to estimate genetic diversity among the 30 rice genotypes using Mahalanobis D2. The clustering pattern grouped 30 rice genotypes into six non-overlapping clusters under drought condition. Cluster number V having highest genotype (8) followed by Cluster VI having six rice genotypes and Cluster II having 5 genotypes. The clustering pattern grouped 30 rice genotypes into six non-overlapping clusters under controlled condition in which Cluster I having six genotypes followed by cluster V grouped with six genotypes and cluster VI also having six genotypes. Barani deep, Nagina-22, Shusk samrat, Nagobanyo Red Cover associated with drought tolerance and high yield. Therefore, these lines may be used as donor parent in breeding programme to develop the drought tolerant rice cultivar having high yield under drought and control conditions or may be released as variety for its cultivation in drought prone environment.
