对从广东、贵州、湖南等地引进及广西本地转化培育的182个杉木无性系进行对比试验,结果显示:参试无性系存在显著的遗传差异,大部分生长量不如广西本地对照,尤其是从广西区外引进的无性系;各无性系造林表现早晚相关性显著,最高系数达0.988;广西本地转化培育的无性系遗传稳定性比区外引进的波动大,决选所需时间也较长;早期选择存在更大的错选、漏选风险,其机率分别为44.44%和29.63%;以材积作为主要性状指标对各无性系作Q型样本聚类,经综合判别分析,从参试无性系中选出广运5、柳327、湖南46等27个生长量比较突出的无性系. A comparative study on 182 Chinese fir clones introduced from Guangdong, Guizhou and Hunan provinces and cultivated locally in Guangxi showed that there was a significant genetic difference between the clones tested, most of which were not as good as the native controls in Guangxi, especially from The introduction of clones outside the Guangxi region; the clonal afforestation performance of early and late correlation was significant, the highest coefficient of 0.988; Guangxi local transformation cloned genetic stability than the introduction of large area fluctuations, the time required for the election is also longer; In the early selection, there was a greater risk of misclassification and missed selection, with a probability of 44.44% and 29.63% respectively. Cluster analysis was used to classify Q clones for each clonal group. Based on the comprehensive discriminant analysis, In the selection of Guangyun 5, Liu 327, Hunan 46 and other 27 more prominent clonal growth.
