Abstract:
Sixteen morpho-agronomic traits were used to study the phenotypic variation and genetic diversity analysis in marigold. The findings revealed significant differences in quantitative and qualitative traits among the genotypes. All the 20 genotypes were grouped in five clusters based on multivariate analysis. Among the clusters, cluster II was the largest group with 06 genotypes followed by cluster III and V each having 04 genotypes and remaining clusters had each 03 genotypes. The maximum intra-cluster distance exhibited by f cluster I, while the lowest by the cluster IV. The inter-cluster distance was highest between the cluster I and III and lowest between cluster II and V. The different clusters have higher mean values for different traits. Among the different clusters mean value, genotypes “Farmer sel-4” from Cluster I, “Af. sel14” from cluster II and “PNG, PBG” or “Farmer sel-7” from cluster III, “Farmer sel-5and Af. sel10” from cluster IV, “Farmer sel-8 and Farmer sel-3” from cluster V respectively deserve to be considered as potent parents for further utilization in marigold improvement programme.
