บทคัดย่อ (EN): On-farm evaluation is the last stage of evaluation in the breeding and selection cycle of Hevea brasiliensis, Five potential clones (RRII 414, RRII 422, RRII 429 and RRII 430) selected based on the performance in breeders trials were passed on to an on-farm evaluation (small holding) in southern Kerala in 2001 to understand regional performance along with the popular check clone RRII 105. These clones were subjected to detailed evaluation. Of the five clones tested, highest tappability was observed from the clone RRII 417 (82%) and RRII 414 (80%) when compared to the control RRII 105 (22%) 7 years after planting. RRII 422 (mean: 74, range: 51-97 g/t/t) registered the highest yield followed by and RRII 417 (mean: 64, range: 43-86 g/t/t) and RRII 430 (mean: 59, range: 37-81 g/t/t) also showed improved yield compared to the check clone RRII 105 (mean: 48, range: 29-66 g/t/t), DRC of these clones varied from 33 to 37% over three years but RRII 422 and RRII 105 remained consistent across seasons. Clones exhibited expected variability in terms of growth, DRC and yield. The interim results demonstrated that the trunk growth and dry rubber yield were corroborating with the breeders data and these clones remained superior to the check variety 11 years after planting. The present study could also identify potential clones among 400 series for southern Kerala and adjoining areas. These results could be useful for growers for adoption of newly recommended clones and reiteration of superiority of RRII 400 series clones.
