, Shubha | Singh, Dhirendra
Principal component analysis was undertaken to estimate variability in 32 potato genotypes. Fourteen principal components accounted for 99.97 per cent variation. The genotypes were grouped into 5 non over-lapping clusters. The maximum intra cluster distance was found in cluster II (3.565) and minimum in cluster III and I (2.531). In general, the clustering pattern was not corresponding to their pedigree. The maximum inter cluster distance of 5.063 was found between clusters I and II, whereas minimum distance 4.213 was found between clusters III and IV. Cluster number III had maximum number of genotypes (08) followed by cluster number V (07), I and IV (5)and II (3). The genotype having maximum inter cluster distance showed maximum diversity, and thus they can be used in hybridization programme.
