520			_aBark rot or black stripe of Hevea brasiliensis caused by Phytophthora spp. is the only economically important disease of the tapping panel. Screening trials were carried out for three consecutive years at four different localities to evaluate the inherent susceptibility of thirty three Hevea clones to black stipe disease. The results indicated that the clones commonly grown in the eastern hemisphere or proved to be potential genetic material for future use show a differential inherent susceptibility with RRIC 130 being the most susceptible. Among the other examined RRIC 119, RRIC 133, RRIC 110, RRIC 112, RRIC 114, PB 86, RRIC 117, RRIM 600 and RRIC 132 were susceptible while BPM 24, RRIM 717, RRIC 116, PB 260, RRIC 121 and RRIC 100 were resistant.
