黄檗无性系种子园母树生长性状评价

Traits of Growth in Clonal Seed Orchard in Phellodendrom amurense Rupr

对黄檗种子园4个种源的26个无性系的树高当年生长量、树高和冠幅进行了分析。结果表明,黄檗不同种源间树高当年生长量、树高和冠幅差异均达到极显著水平(F值分别为7.84**、19.28**和11.62**),各性状遗传力分别为0.25、0.45和0.33,受中等遗传控制。各区无性系间树高当年生长量、树高和冠幅差异均显著或极显著。通过多指标综合评分及最优性状综合分析,选出23号、1号、2号、4号、24号、10号和25号为优良无性系,其中1号为最优无性系。

Current annual height increment ,height and crown of 26 clones in the 4 provenances in Phellodendron amurense seed orchard were measured .The results showed that current annual height increment ,height and crown showed significant variations ( F=7.84** ,19.28** and 11.62** )in different provenances .Genetic heritability of current annual height increment ,height and crown were 0.25 ,0.45 and 0.33 respec-tively .There were significant variations in current annual height increment ,height and crown in different clones .These results indicated that No.1 clones was selected as the best clones and No.23 ,No.2 ,No.4 ,No.24 ,No.10 ,No.25 clones were selected as superior clones .
