Abstract

Betelvine is a heritage crop of India and is cultivated for its fresh leaves which are masticatory. As it is a dioecious, Kapoori accessions belongs to male plants which are useful for hybridization programmes in betelvine. Genetic diversity is major tool for crop improvement, so there is a need to analyse the diversity in the accessions. Genetic divergence was assessed using mahalanobis D2analysis for 17 betelvine accessions for 18 characters. Based on morphological characters the accessions were grouped into five clusters, the highest inter cluster distance was observed between cluster V and IV, which indicates that there was much diversity and the highest intra cluster distance was observed in cluster II which indicates that it has most divergent accessions within the cluster. Based on cluster means, cluster IV has highest mean values for plant, leaf and yield characters. Hence these divergent and the genotypes with desirable character can be used as male parent for further crop improvement programme in betelvine.

Conclusion

The cluster analysis depicts the distance between and among the accessions. 17 accessions grouped into 5 clusters. In this study cluster (Tellaku Ponnuru and Swarna Kapoori) recorded the maximum diversity with respect to morphological variations. These accessions can be used for the purposes of high yielding traits as a male parent in the hybridization programme.
