摘  要：
对营建于1985年、引种自全国14个初级种子园的84个杉木半同胞家系子代区域试验林的4个林龄段(5年、8年、26年及30年)的林木生长情况进行统计分析。结果表明,在不同生长阶段,多数家系子代的树高、胸径和材积生长指标均呈极显著差异,且早晚生长表现较稳定。以30年生时的材积作为评选依据,有产自广西、贵州、湖南和福建等省区的15个家系入选为优良家系,其家系平均材积、材积现实增益和遗传增益分别达到0.335 0m3、15.73%和11.93%以上,其中产自广西的入选优良家系平均遗传增益高达65.52%。

摘  要：
Introduced from 14 primary seed orchards nationwide,and established from 1985,84 Cunninghamia lanceolata stands of half-sib progeny were analyzed on 4 ages(5-year,8-year,26-year and 30-year). The results showed that there were significant differences among most family progenies in tree height,DBH and volume at different stages of growth. The growth traits presented stable in juvenile-mature period. According to the volume of 30-year-old families,15 families produced from Guangxi,Guizhou,Hunan and Fujian were finally selected as superior families. The average volume,volume gain and genetic gain of the superior families were more than 0. 3350m3,15. 73% and 11. 93%,respectively,among which,the average genetic gain of superior families produced from Guangxi was up to 65. 52%.
