| 摘 要： | 以20个山桐子无性系为研究对象,通过分析其生长量、结实量、含油率等性状差异进而评价筛选优良无性系。结果表明:不同无性系间的果穗性状、果实表型、果实含油率存在显著差异;果穗长宽与果穗重相关性极显著,果实大小显著影响单果重量的大小;利用主成分分析法,综合评选出6个优良无性系,入选率30%,入选无性系具有含油率高、结实量大、树体健壮等特点。本研究筛选的山桐子优良无性系为四川地区选育良种或品种提供良好物质基础。

| Abstract: | Taking 20 clones of Idesia polycarpa as the research object,the excellent clones were evaluated and screened by analyzing the difference of growth,fruiting,oil content and other characters.The results showed that there were significant differences in panicle characters,fruit phenotype and fruit oil content among different clones.There was a significant correlation between cluster size and cluster weight.Six excellent clones were selected by principal component analysis,and the selection rate was 30%.The selected clones had the characteristics of high oil content,high seed yield and strong tree body.The selected superior clones provided a good material basis for breeding fine seeds or varieties in Sichuan. |
