摘要：对营造在福建省邵武市11 a生杉木无性系试验林的树高、胸径、材积和木材基本密度这4个主要生长和材质性状进行测定和分析,并采用指数选择法进行优良无性系选择。结果表明:4个主要生长和材质性状在无性系间达极显著差异水平,且有较高重复力(除材积外)和中等的变异系数;3个生长性状间的遗传相关均为密切正相关,3个生长性状与木材密度间则均为弱度遗传负相关。采用材积和木材密度两个性状,应用选择指数初选出8个中期表现较好无性系,它们在木材密度基本保持试验群体平均水平的情况下,材积比试验群体平均值大51.65%,比试验对照大102.68%。
The four main traits of growth（H,D, V） and wood density in 11 -year- old Chinese fir clone plantation in Shaowu City in Fujian Province were determined and analysed and the index selection was adopted in good clone selection. The results showed that the four main traits were highly significant on each trait of the clones, and their repeated ability was high （except V） and their variation coefficient was middle. The genetic correletion coefficient was high among three growth traits, and the genetic correletion coefficient was weakly negative among three growth traits and wood density. Eight better clones were selected in the middle period by index method with two traits of V and wood density, keeping wood density unchanged, V increased by 51.65% compared to the experiment population and by 102.68% compared to the CK.
