Identification of Hevea clones is tedious but very essential for research and for cultivation. Studies on seed coat sculpturing using scanning electron microscope (SEM) have revealed that seen surface pattern is characteristic and constant for a given species or a group of species. An attempt was made to identify some popular clones by seed coat sculpturing under SEM. The seed surface of clone RRII 105 is areolate and areoles are granulated and well differentiated. Areoles have various sizes and shapes in Tjir 1. The seed surface of Gl 1 is verrucated with cloudy pattern whereas in PB 260 it is smooth psilate. In PB 312, the seed surface is rough with granules but in KRS 128 it is faintly reticulate with cloudy pattern. SEM studies have elucidated significant variation among clones for seed coat pattern. Hence seed coat micro morphology can be used as a vital parameter in the identification of Hevea clones.
