Abstract

The present investigation was conducted with 60 genotypes including three checks (NDCor- 1, NDCor-2 and Hisar Anand) in Augmented Block Design in 4 blocks (15 genotypes + 3 checks in each block). On the basis of 12 characters, the non-hierarchical Euclidean cluster analysis was used to examine the genetic divergence across 60 coriander germplasm collections. The 63 coriander genotypes were divided into 7 groups. The intra-cluster group means for 12 characters varied significantly amongst the various clusters. Therefore, crosses between members of clusters which are having high cluster means for important characters coupled with high inter-cluster distances between them, are likely to be more useful. Cluster VI, followed by cluster I, had the highest cluster mean for seed yield per plant, whereas cluster VI, followed by cluster VI, had the lowest cluster mean for seed yield per plant. Crosses between cluster members who are far apart from one another are likely to result in segregates that are desirable. In this situation, cluster III recorded the most intra-cluster distance, whereas clusters II and VII recorded the greatest inter-cluster distance, and cluster V recorded the greatest number of genotypes.

Conclusion

The present study grouped the 63 coriander genotypes into 7 diverse clusters and delineated few important traits contributing towards total variability crosses between members of clusters which are having high cluster means for important characters coupled with high inter cluster distances between them, are likely to be more useful. This could be the basis for planning an effective hybridization programme and selection of genotypes for further coriander improvement programme.
