热研７—１８—５５橡胶无性系，是华南热带作物科学研究院采用ＲＲＩＭ６００×ＰＲ１０７培育出来的后代．国营大丰农场、新进农场于１９８０年引进建立生产性系比试验区，经过１３年的系统实定、观察及研究表明。其产量比ＲＲＩＭ６００高产５９．９％，风害断倒率比ＲＲＩＭ６００轻１１．７个百分点；炭疽病３－５级率比ＲＲＩＭ６００轻９％，死皮率、指数分别比ＲＲＩＭ６００轻４．２％及８．７；苗期生长比ＲＲＩＭ快７．９％；其他性状亦表现良好．因此．该种具产量较高、抗性较强、副性状较优良等特点，是个优良的橡胶无性系．
Hot research 7-18-55 rubber clones, is the South China Institute of Tropical Crops RRIM600 × PR107 offspring of future generations. State-owned Dafeng Farm and New Farm were introduced in 1980 to establish a productive ratio test area. After 13 years of systematic implementation, observations and studies have shown. Its yield was 59.9% higher than that of RRIM600 and 11.7% lower than that of RRIM600. The 3-5 rate of anthracnose was 9% lower than that of RRIM600, and the mortality rate and index of dead skin were 4.2% And 8.7 respectively; seedling growth 7.9% faster than RRIM; other traits also performed well. therefore. The species with higher yield, strong resistance, vice traits and more excellent, is an excellent rubber clones.
