在南京林学院育种室主持下,1983年全国十个省(区)十四个杉木嫁接种子园采集了112个优良家系种子,1984年春子我省乐昌县龙山林场进行播种试验。育苗结果说明:不同省(区)间子代苗高生长差异极显著,其中以贵州、湖南等中心产区的家系表现最好。不同家系间高生长差异亦极显著,其中湖南大堡子44号及贵州锦屏61与全国对照相比,其差异分别达显著水平和较显著水平。
In 1983, under the auspices of Nanjing Forestry College breeding room, 112 fine family seeds were collected from fourteen Chinese fir seed grafting orchards in 1983 in ten provinces (districts) of China. In the spring of 1984, sowing experiments were conducted in Longshan Forest Farm, Lechang County, Liaoning Province. The results of nursery showed that the differences of seedling height growth among different provinces (districts) were significant, among which the families in Guizhou, Hunan and other central producing areas had the best performance. The differences in height growth among different pedigrees were also significant. Among them, 44 in Da Bao Zi of Hunan Province and Jin Ping 61 in Guizhou Province showed significant and significant differences respectively compared with the national control.
