摘要
以中国热带农业科学院试验场初级系比和高级系比区林段为试验材料,通过系统鉴定确定其特性。结果表明,热研8-79是一个高产、早熟橡胶树优良品种。在高级系比区,1～11割年平均年产干胶5.77kg/株(2504kg/hm2),为对照RRIM600的152%(151%)。其干胶含量高,产胶潜力大,抗风性与RRIM600相当,但生长量与开割率均与对照差异不显著。推荐在海南中西部轻风区中规模配置。
Rubber trees（Hevea brasiliensis） of stands of rubber plantations in primary and advanced clonal trials located in Hongcheng Team of Experimental Farm, CATAS were used as materials to identify the characteristics of Clone Reyan 8-79 systematically. The results showed that Reyan 8-79 is a high-yielding early starter clone of rubber trees. This clone yielded 5.77 kg/tree/year 504 kg/hm^2/a over the first 11 tapping years, which was 52% or 51% higher than that of the control clone RRIM600. The dry rubber content was high and the potential yield was promising. This clone was similar in windfirmness to RRIM600. Meanwhile the girth and percentage tappability were not significantly different between Reyan 8- 79 and the control. It is hence recommended for moderate scale extension in gentle wind areas in the central and west parts of Hainan Province .
