520			_aMorphology, viability, storage and germination of seeds Hevea Brasiliensis are described. The seed is large, ovoid dorsiventral with irregular bark brown and grey lines or blotches on the seed coat. These characters are specific for each clone and used for clone identification. Hevea seeds are recalcitrant due to thier high moisture content, and lose viability even with short term storage under optimum conditions, hence they should be planted soon after collection. Seeds of good physiological quality can be stored for up to 4 months without losing viability under specific conditions. Seed viability can be detected by germination tetrazolium, electrical conductivity of FFA tests. Seeds collected from well maintained polyclonal gardens can be utilized for genetic improvement of rubber.
