Genetic Diversity Analysis Using D2 Clustering in Small Cardamom (Elettaria cardamomum Maton)

Ninety cardamom accessions (Elettaria cardamomum Maton) were subjected to Tocher’s clustering, in order to assess the genetic diversity available in the accessions. The analysis showed wide diversity for growth and yield attributes among the accessions. The accessions were grouped into eight clusters. Based on the inter cluster distance, the accessions belonging to the most distance clusters can be used for hybridization programmes to produce better and promising hybrids. Mahalanobis D2 method provides an efficient technique to identify the genetic divergence present in the population. This technique helps in the selection of genetically divergent parents and can be exploited in the hybridization programme.
