摘要
通过对杉木无性系生长性状遗传力、性状早晚相关及不同年度苗木生长的稳定性分析 ,探讨了杉木无性系苗期选择的可靠性 .结果表明 ,杉木无性系大多数生长性状的遗传力较高 ,性状早晚相关明显 ,而且大多数无性系在不同年度苗木生长表现较为稳定 ,因此杉木无性系苗期选择具一定可靠性 。
This paper probed into the reliability of clones selection in Chinese fir on seedling stage by studying the heritabilities of growth characters of Chinese fir clone,correlations of growth characters between early and later stage,and by analysing the stability of growth performances of one year old seedling of Chinese fir clones in different years.The result shows that most growth characters of Chinese fir clones have high heritabilities,the correlations between early and later stage of growth characters are obvious,and growth performances of seedling of most Chinese fir clones are stable in different years.So it is reliable to make clones selection in Chinese fir on seedling stage,and the height of one year old seedling can be used as the main growth index for clones selection in Chinese fir on seedling stage.
