Abstract

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.
