马尾松是湖北省的重要树种之一,现有的大部分优树均在南方各省经测定后引进。为了扩大马尾松的育种群体,丰富我省马尾松优树资源,提高育种水平和林业生产力,1996年10~11月,湖北省林木育种中心组织工作人员在鄂西北的恩施市、来凤县、咸丰县、鹤峰县、宣恩县及鄂西南的宜昌县、枝城县、远安县进行了马尾松选优,并在太子山种子园试验地进行了播种试验。对1年生苗高的方差分析表明:各家系间的苗高生长差异显著,重复间差异不显著。其中以鄂西南的优树家系高生长表现最好。
Masson pine is one of the important tree species in Hubei Province. Most of the existing excellent trees are introduced in the southern provinces after the determination. In order to expand the breeding population of Masson pine and enrich the resources of masson pine trees in our province to improve the breeding level and forestry productivity, from October to November 1996, the staffs of the Forest Breeding Center of Hubei Province organized the project in Enshi City, Laifeng County, Xianfeng County, Hefeng County, Xuan’en County and Yichang County, Zhicheng County and Yuan’an County of southwestern Hubei Province were selected for their excellent selection. Seed sowing experiments were conducted in Taizishan Seed Park. Analysis of variance of 1-year-old seedling height showed that there was a significant difference in seedling height growth among all the families and no significant difference between the two repetitions. Among them, the superior tree growth in southwestern Hubei Province was the best.
