D2 statistic

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.

In the present study, 22 tomato (Solanum lycopersicum L.) genotypes were evaluated to study the extent of genetic diversity through 20 quantitative traits. The genotypes were categorized into 5 distinct clusters using D2 statistics. Cluster I had the maximum number of genotypes (8), followed by clusters IV and V (4 genotypes each) and clusters II and III (3 genotypes each).

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).

The study revealed that maximum contribution to divergence was made by plant height, seed yield per plant and oil content. Cluster I composed of restorer genotypes which are having higher mean value for volume weight. RHA-91, which was included in cluster III recorded maximum mean value for oil content. Cluster V (CMS109B) showed maximum mean value for oil yield and seed filling per cent. Based on cluster mean values for a given characters, we can select highly divergent genotypes from the respective clusters and can be used in hybridization work.
