Comparative Test Study on Cunninghamia lanceolata Clones
摘要
Abstract
The comparative test was conducted to study the differences of 28 Cunninghamia lanceolata clones from Guangxi and Hunan. The results showed that there were highly significant differences in tree height, diameter and individual volume among clones. The broad-sense heritability of tree height, diame- ter and individual volume in clones was relatively large, which could reach 0. 9 in 17-year-old forest. There were 6 clones such as Liu No. 46, Liu No. 300 and Liu No. 88 which were selected by the standard of stem volume, among which the highest individual volume genetic gain was over 23. 12%. The tree height, diameter and individual volume of clones were stable among the tests for three years.关键词
