摘要
通过10年生红皮云杉全分布区9个参试点。9个采种点种源子代性状的方差分析、多点联合分析、稳定性分析、生产力指数分析、简相关分析。结果表明:①利用10年生红皮云杉种源试验结果进行最佳种源的早期选择是可行的。②将参试种源按照生长及遗传稳定性划分成四种类型:即低产稳产型(包括穆棱、爱辉、高峰);中产稳产型(包括桦南、凉水);高产非稳产型(包括乌伊岭);高产稳产型(包括大丰、天桥岭、柴河)。在种源遗传力估算的基础上进行了遗传增益估算,并对优良采种点的推广前景进行了评价。
This papar concerns data from ten year old progenies of picea koraiensis in nine provenances trials. By variance analysis, correlation study, productivity index and genetic stability analysis, the results indicate that (1) it is reliable and feasible to make early selection of picea koraiensis in ten year old; (2) It shows a significant interaction between the provenances and sites. According to height growth of the provenances, and its genetic stability,nine provenances, have been divided into four types, which is the type with low and stable productivity (including Muling,Aihui and Gaofeng provenances); the type with middle and stable productivity (Huanan and Liangshui provenances); the type with high and unstable productivity (Wuyiling provenance); the type with high and stable productivity (Dafeng, Caihe and Tianqiaoling provenances). (3) besides, it also evaluates the heritability and genetic gain of the provenance growth, as well as the practical prospect and its social benefits by using the optimal provenances in forestry product.
