摘要
热研７－２０－５９是一个速生高产而相对晚熟的橡胶树优良无性系，在基本试区１～９割年干胶产量逐年递增，第 ９割年平均年产干胶为 ５．７９ ｋｇ／株，２０５７ ｋｇ／ｈｍ２，分别比对照 ＰＲ１０７增产 ８６．８％和 ７３．４％；头９割年平均年产干胶３．９５ｋｇ／株， １４６７ｋｇ／ｈｍ２，分别为对照的１７８．７％和 １６８．６％。此外，该品种抗风能力较强，风害后有较强的恢复生长能力。在海南农垦 １９９８年橡胶树优良品种汇评中被评为中规模推广级品种。
SCATC 7-20-59 is a promising rubber clone with high yield and rapid growth, and needs more time to approach the period of high yield compared to the control clone. The dry rubber yield was increasing with the tapping year during the first to the ninth tapping year in the trial and reached 5.79 kg per tree or 2057 kg per hectare in the ninth tapping year, which was 86.8% or 73.4% higher than that of the control clone PR107 respectively. The annual mean yield was 3.95kg per tree or 1467kg per hectare over the first nine tapping years, 78.7% or 68.6% higher than the control clone respectively. Meanwhile, the clone showed better wind tolerance and re-growth after wind damage. It was hence recommended for moderate scale extension in 1998.
