Abstract: An experiment was carried out to analyze multivariate analysis based on cluster and principal component (PC) for yield and its eighteen contributing traits in 30 Mysore mallige local collections during 2018-19. The cluster analysis categorized all 30 Mysore mallige into 2 major clusters. Extreme genetic divergence was estimated among clusters. Average intra-cluster distance was found maximum (D2=1254.18) between cluster 1 and cluster 2. The character flower bud weight (53.10%) contributed maximum to the genetic divergence among the genotypes followed by number of petals (18.85%). Highest cluster mean values length of corolla tube, length of the leaf was found in cluster I followed by cluster II. Principal component analysis revealed that first five principal components (PC1, PC2, PC3, PC4 and PC5) accounted for 83.44% of the total variations with the proportionate contribution values of 40.88%, 18.42%, 10.17% and 8.19% respectively. Promising diverse parents identified based on cluster and PC analyses could be selected for future crop improvement.
