摘要:
在优选的20个榔榆实生单株上采集接穗,嫁接在榔榆砧木上,对其苗期生长性状进行测定分析。结果表明,无性系间苗高和地径差异均达极显著水平,具有较丰富的遗传变异。各无性系苗高平均值为1.78 m, 变幅为1.2—3.0 m;地径平均值为1.47 cm,变幅为1.0—2.4 cm。无性系苗高重复力为0.388,地径重复力为0.319。采用布雷金多性状综合评定法对榔榆苗高和地径加权评定,选出优等无性系5个。结合遗传增益估算选出JN-02和 JD-08具有速生潜力,苗高遗传增益分别为7.12%和6.39%,地径遗传增益为5.71%和4.70%,可为后续榔榆无性系造林试验提供材料。
Abstract:
Growth characters of 20 Ulmus parvifolia clones in seedling stage were determined. Results showed that seedling height and collar diameter among clones had significant differences, with plentiful genetic variation. The average height among clones was 1.78 m, with the amplitude range of 1.2—3.0 m. And the average collar diameter was 1.47 cm, with the amplitude range of 1.0—2.4 cm. The repeatability of seedling height, collar diameter were 0.388 and 0.319 respetively. Five clones of U. parvifolia were selected by method of comprehensive multi-character evaluation, among which, Clone JN-02 and Clone JD-08 were selected as optimal for afforestation test.
