Fifty traditional as well as commercial rice (Oryza sativa L.) genotypes were analyzed using Mahalanobis' D² statistics, considering nine plant variables in deciding the most appropriate parental candidates for hybridization. Based on D² standards, the genotypes were divided into nine diverse groups. Notably, Cluster I held the greatest number of genotypes (twenty) while clusters VIII and IX housed the fewest, one genotype each. Clusters V and IX showed the wider between cluster distance and cluster VII with the highest within cluster distance which showed significant genetic heterogeneity was seen among the genotypes in these groupings. The greatest cluster means for single plant yield, as well as a number of other yieldrelated characteristics, were notably shown by clusters II, IV, VI and VII. While, earliness trait was well performed by cluster V. It is advised to give genotypes from clusters II, IV, VI and VII priorities while moving forward with hybridization in order to generate unique recombinants. [ABSTRACT FROM AUTHOR] |
