Significant clonal variation was recorded for al the traits studied. The existence of considerable genetic diversity among the clones was revealed. Employing the Mahalanobis'D2 statistic, the clones were found to belong to eight genetically divergent clusters. Geographic diversity had not relation with genetic diversity. Volume of latex, plugging index and dry rubber yield contributed most towards genetic divergence ER -
