Abstract
Coconut populations of Indian Ocean Islands of Madagascar, Mauritius and Seychelles were clustered using principal component analysis. A total of 28 vegetative, reproductive and fruit characters were used for analysis. Floral, foliar and fruit characteristics analysis indicated the usefulness of 11 characters for clustering. Five clusters were obtained on the basis of these characters. Nut characters were also found to be good for cluster analysis. All the dwarfs were in one cluster when vegetative and nut characters were considered. While selected, characters of two tails, Comoros Tall and Coco Bleu Tall were also included along with dwarfs indicating die doubtfulness of the genetic nature of these materials. These may be in fact dwarfs erroneously recorded as tails. Cluster analysis did not show any geographical affinity within the region.
