Abstract

Principal component and cluster analysis were used to examine diversity among growth traits and yield components of 43 accessions of taro at the Regional Centre of Central Tuber Crops Research Institute, Bhubaneswar, Orissa, India. Principal component analysis identified three vectors with minimal Eigen value criterion, which explained 78% of the variation in the traits. Varimax rotation enabled loading of similar type of variables on a common principal component. The genotypes were further subjected to Hierarchical cluster analysis that resulted in eight clusters containing one to seventeen genotypes. The maximum number of genotypes was included in cluster III. The accessions TL-3 and Megh-1 (Meghalaya) were found to be far apart from other accessions and can be utilized for further breeding programmes.
