【摘要】 热研８－３３３是一个早熟高产、干胶含量较高，并有一定抗寒力的橡胶树优良新品种。在高比区，其干胶产量在第３割年就高达 ５．８２ｋｇ／株和 ２ ６２７ ｋｇ／ｈｍ２，第 １～７割年平均年产干胶４．９９ ｋｇ／株和 ２ １７２ ｋｇ／ｈｍ２，分别比对照 ＲＲＩＭ６００增产 ５７．９％和 ７２．２％。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，可在海南中西部中风区推广种植。更多还原

【Abstract】 SCATC 8-333 is an improved clone with the characteristics of high yield, precocity, high dry rubber content and cold resistance. An advanced trial on SCATC 8-333 showed that the annual mean yield of dry rubber during the first to the, seventh tapping year was 4.99 kg/tree or 2 172 kg/hm2, which was 57.9 % or 72.2 % higher than the control clone RRIM600. The yield was as high as 5.28 kg/tree or 2 627 kg/hm2 at the third tapping year. The clone was hence recommended for moderate scale release in 1998.更多还原
