产量这些试验已在植株的原生皮上割胶八至十年。因只有少数几个试验有第十年的产量数据,所以在统计平均产量时没有计算这年的产量。同样,有些试验虽已在第三割面上割胶四年,但平均产量只算前三年的。表1列出第二和第三剖面的产量数据,并按割胶十二年平均产量高低排列RRIM600组无性系。在头九年,以RRIM600、623和628的产量最高,分别比对照RRIM501的产量高

Yields These tests have been tapping on the primary hide of plants for eight to ten years. Since only a few trials have the tenth year of production data, the average production for the year was not calculated for this year’s production. Similarly, although some tests have been tapping the third cut surface for four years, the average yield is only calculated in the first three years. Table 1 shows the production data of the second and third sections and arranges RRIM600 clones according to the 12-year average yield of tapping. In the first nine years, the highest yields were obtained with RRIMs 600, 623 and 628, respectively, as compared with those of the control RRIM501
