| 摘 要： | １９８７年采集２３８个杉木二代种子园自由受粉家系，进行子代测定。８年生结果显示，杉木二代种子园中各家系间生长性状存在显著遗传差异。从中选择优良家系进行造林，生长量能比杉木二代种子园子代平均表现增加６％，比杉木一代种子园最优无性系增产２０％以上。 |
| 关 键 词： | 杉木 第二代种子园生长 子代测定 增产效益 |

| Abstract: | Chinese fir ] is a fast growing evergreen coniferous tree species with wide distribution area (covered all the subtropical in southern China). It has very straight stems, special sweet smell, resistance to inscets and decay, easy to asexual propagation etc. Chinese fir has the evolutionary history of 70 millinon years and has been cultured for more than 2000 years in China. NF(Nanjing Forestry UniversityFujian Province) project had completed the secondary generation genetic improvement in Chinese fir. The first secondary generation seed orchard was established in 1983. 238 open pollination families from the secondary generation seed orchard in Chinese fir were collected for progeny testion in 1987. The results (8 years) showed that there was of significant genetic difference in growth traits among families. The selected families will be increased 6 % to the mean of progeny from the secondary generation seed orchard and 20 % to the potimal cline in growth. |
