本文主要报导应用无性繁殖性状可遗传的原理,综合利用现有橡胶树优良无性系的不同部位抗寒、速生、高产的特性.进行冠、干、砧三合树组合选配试验的初步结果.本试验经过十年观测,四年测产,初选出闽林71—22/、闽林71—22/南华1等二个优良三合树组合和优良的树冠无性系闽林71—22.与93—114/GTl(?)、93—114/南华1相比,可提高抗寒力0.5级左右;树围增长较快,可提早一年投产;干胶产量可增加40.44%和47.58%.且保存率和开割率均较高,付性状优良,其经济效益十分显著.
In this paper, the principle of heritable inheritance of clonal traits was reported, and the cold-hard, fast-growing and high-yield characteristics of different parts of the existing excellent clones of rubber trees were comprehensively used. After ten years of observation and four years of test, the experiment selected two excellent three-tree combinations, namely Minlin 71-22 /, Minlin 71-22 / Nanhua 1, and excellent forest clone Minlin 71-22. 93-114 / GTl (?), 93-114 / Nanhua 1, can improve the cold resistance of about 0.5; tree fence grow faster, can be put into operation one year earlier; glue yield can increase 40.44% and 47.58%. And the preservation rate and the opening cut rate are higher, pay excellent traits, its economic efficiency is very significant.
