| Abstract: | Stands of young tapping rubber trees of Clone Reyan 87-4-26 (Hevea brasiliensis) selected by Rubber Research Institute was observed in terms of yield, dry rubber content, coldhardiness and other physiological parameters. This clone had an annual mean dry rubber content of 28.42%, highly significant-ly higher than that of the control RRIM 600; yielded 2.03kg/tree/year, obviously higher than that of the control; was more coldhardy with the cold injury scale being 1.11, much lower than that of the control, and; had higher sucrose content and stable regeneration of latex, which is a good physiological background. Therefore this clone is a promising clone which deserves continuous tracking and observation. |
