Sharma, et al) Indian Society of Genetics and Plant Breeding, New Delhi, 1995, p1434-1440 N2 - The genus Hevea belonging to the family Euphorbiaceae comprises of ten species. Among these, the para rubber tree, Hevea brasiliensis (Willd. ex Adr. de juss) Muell Arg. is the only species commercially exploited for natural rubber, which provides the livelihood for over thirty million people in the world. The economic life span of the tree is about 30 to 35 years. The tree is diploid (2n= 2x = 36) with a basic number of x = 18 [1-5]. Triploids in this species were reported for the first time from the Rubber Research Institute of India [6-7]. This communication deals with the comparative cytomorphological investigations on a spontaneous triploid and a synthesized one ER -
