“柚木地理种源选择研究”历经五年系列配套技术研究和良种控制与推广应用,取得了可喜的成果:①收集并保存热带、南亚热带11个国家75个地理种源、250多个无性系,建成8片3.3ha柚木基因库,提出了遗传改良的策略、途径和方法。②进行5～15年的综合评价,选出8个优良种源,其材积生长量为标准种源的125％～190％,年平均高生长1.4～1.75m,胸径生长量1.6～1.98cm;抗旱、抗病的遗传增益为20％～36％。③评选出第一批21个杂交子代无性系,其材积生长量为标准无性系的130％～250％。④种源/优树的组培——微穗 “Teak geography provenance selection research” After five years of series of supporting technology research and improved seed control and promote the use of gratification has made gratifying achievements: ① collection and preservation of tropical and subtropical 11 countries 75 geographic provenance, more than 250 clones , Built 8 3.3ha teak gene pool, proposed genetic improvement strategies, ways and methods. ②Comprehensive evaluation from 5 to 15 years, 8 elite provenances were selected, whose volumetric growth was 125% -190% of the standard provenances, the average annual growth was 1.4 ~ 1.75m and the DBH growth was 1.6 ~ 1.98cm; Drought, disease resistance genetic gain of 20% to 36%. ③ selected the first batch of 21 hybrid progeny clones, the volume growth of 130% to 250% of the standard clones. ④ provenance / tree tissue culture - micro-spike
