| 摘 要： | 15个光皮树无性系对比试验在湖南省龙山县可立坡林场和湖南省林业科学院试验林场进行。通过对15个无性系的生物性状和经济性状进行遗传测定、方差分析、主成分析和综合评分。结果表明：无性系早实性和丰产性受环境与遗传的作用存在着明显的差异；无性系主要性状遗传特性表现突出，尤其单株果穗数遗传力高达75．82％，单株鲜果产量遗传增益高达5．54％，无性系综合评分由高到低排序：G-15〉G-13〉G-5〉G—11〉G-14〉G-2〉G-1〉G-3〉G-10〉G-9〉G-12〉G-6〉G-8G-7〉G-4。

| Abstract: | Contrast experiment of 15 Swida wilsoniana clones was carried out in forest-experiment-station of Hunan Forestry Academy and Kelipo experimental forest farm of Longshan County of Hunan Province.The biological and economic characteristics of 15 S.wilsoniana clones were analyzed by heritability estimation,ANOVA analyses,PCA and grading method.The results showed: 15 clones had significant differences on the precocity and high yield controlled by genotype X environment interaction,whose genetic character of mai... |
