摘要
热研88-13在基本无性系试验区8年的系统鉴定结果,平均年株产干胶5.04公斤,比 RRIM600高产35.1%;平均年亩产干胶113.1公斤,比 RRIM600高产43.2%;抗风能力与 RRIM600相当,树冠耐寒能力比 RRIM600稍强,但割面寒害敏感;胶乳分子量为121万,抗氧指数为90,机械稳定度比 RRIM600稍高,胶乳质量比较好,基本符合中等规模推广品种的标准。
A serial clone trials on clone SCATC 88-13 over eight years showed that themean yield of dry rubber was 5.04 kg per tree per year,which was 35.1% higher thanthat of the control clone RRIM600,and the mean yield of dry rubber per ha was1696.5kg/y,which was 43.2% higher than that of the control clone RRIM600.Thewind tolerance of SCATC 88-13 was much the same as RRIM600.Its crown cold endu-rance was slightly better than that of RRIM600 but its panel was susceptible to colddamage.The molecular weight of latex from clone SCATC 88-13 was 121×10~4,PRI(Plasticity Retention Index)was 90 and MST was slightly higher than that of RRIM600,indicating better latex quality of SCATC 88-13.The clone is thus consideredsuitable for moderate commercial planting.
