บทคัดย่อ (EN): Performance of ortet and hybrid clones was evaluated in the on-farm trial at Shaliackary Estate (Punalur, Kerala). Mean girth at opening ranged from 44 cm in RRII 51 to 49 cm in PB 255. Girth of check clone RRII 105 was 45 cm. Regarding tappability at opening year, clone PB 255 had high tappability (73%) while RRII 51 showed minimum tappability (40%). RRII 105 showed a tappability of 53%. Based on data on mean yield of rubber in the A panel in the experimental clones, PR 255 showed maximum yield (1301 kg/ha/yr) while PB 255 showed minimum yield of 1136 kg/ha/yr. Check clone RRII 105 recorded maximum yield (1578 kg/ha/yr). Under controlled upward tapping system, there was remarkable increase in rubber yield. While average yield of the clones in the virgin panel was 1248 kg/ha/yr, the average yield in the higher panel (under CUT system) was 2644 kg/ha/yr, RRII 176 recorded a maximum mean yield of 3782 kg/ha/yr followed by RRII 51 (3501 kg/ha/yr). The check clone RRII 105 recorded a comparable yield of 3105 kg/ha/yr. It is also worthwhile to note that RRII 176 (Mil 3/2 x PB 5/60) which yielded more than 3500 kg/ha/yr of dry rubber as compared to PB, PR and SCATC clones, also had previous records of only mild incidence of abnormal leaf fall and powdery mildew.
