Mahalanobis D2 analysis
-
The study was carried out with twenty-four genotypes of rice during the Spring season, 2020 in Hanoi, Vietnam in order to exploit the attributes and divergence of quality properties from existing rice cultivars in North Vietnam. The rice genotypes were characterized based on ten quality parameters of milling, physical appearance and physiochemical characters using Mahalanobis D2 statistic

Genetic diversity among 30 advanced breeding lines of groundnut were estimated using Mahalanobis D2 statistic for 21 characters. The analysis of variance revealed significant differences among the advanced breeding lines for all characters. Based on Tocher's method, 30 advanced breeding lines were grouped into ten clusters.

The present experiment was carried out using 51 genotypes at Vegetable Research Centre of G. B. P. U. A & T., Pantnagar, during kharif season of 2019. Mahalanobis D2 statistics was worked out using 11 quantitative characters to assess the degree of genetic divergence. On the basis of value generated using Tocher’s method, 51 genotypes were grouped into six clusters. Cluster I is largest with 42 genotypes followed by clusterII and III with 3 genotypes and cluster IV, V and VI containing 1 genotype in each.

The observations were recorded on five randomly selected plants and the mean values were subjected to Observations were recorded on 24 quantitative characters and data was subjected to statistical analysis using Mahalanobis D2 (1936) statistic to assess the genetic divergence. The genotypes were grouped on the basis of minimum generalized distance using the Tocher’s method (Rao, 1952).

Genetic diversity among sixty three okra genotypes was estimated using Mahalanobis D2 statistic. The genotypes were grouped into nine clusters. The maximum number of genotypes was found in cluster I (36) followed by cluster III (15) and Cluster II (6). Remaining all were solitary clusters with single genotype.
