D2 ANALYSIS IN VIRGINIA RUNNER GROUNDNUT GENOTYPES

Published on

Analysis of genetic diversity using Mahalanobis' 0 2 statistic was carried out in 35
genotypes of virginia runner groundnut. These genotypes were grouped into seven
clusters. Cluster I had the maximum number of genotypes. The analysis further indicated
that the genotypes of common geographic origin or same location were grouped into
different clusters which suggested a lack of relationship between genetic and geographic
diversity. The intra- and intercluster average 0 2 values indicated maximum statistical
distance between clusters II and VII, followed by clusters VI and VII. Cluster VII recorded
highest mean kernel yield/plant, pod yield/plant, biomass yield/plant and recovery
percentage.
 

Keywords: Cluster, ecogeographical regions, pod yield, genetic variability, diverse parents, groundnut.
