| 摘 要： | 运用主成分分析法对初选的41个锥栗单株的7个经济性状进行了分析,确定了评价单株优劣的2个综合指标,并以综合指标的加权值大小作为单株排序和分类的标准。笔者建议,今后需继续在大果类型和中果类型单株中进一步进行无性系的再选择;并注意选择小果类型中优良和特殊性状的单株;对野生类型单株尽量收集,作为种质资源予以保存。

| Abstract: | 7 kinds of economic characters of nuts from 41 individual plants in Castanea henryi were analyzed,by principal component analysis,and two comprehensive indexes were selected as assessment indexes of individual characters,and weighted value of comprehensive indexes were taken as standards of individual sorting and assorting.Otherwise,some suggests were put forward,concluding that further clonal selection of big fruit type of and middle fruit type of individual plants need to be done in future;some fine litter fruit type of and special type of individual plants should be selected;wild individual plants should be collected as many as possible and conserved as germplasm resources. |
