25年生马尾松优树子代生产力评价及家系选择
Productivitv evaluation and family selection of 25-year old plus tree progeny in Pinus massoniana
摘要
Abstract
An investigation and analysis on a 25-year old progeny test stand of Pinus massoniana showed that there were significant genetic variations in height, diameter at breast height (DBH) and volume among different families. The family her-itability of height, DHB and volume was 0. 428, 0. 565 and 0. 610, respectively. Using an index selection equation built with height, DHB and volume, 20 superior families and 100 individuals were selected. Average family genetic gain of volume was 26. 0% , and average volume of individuals was 122. 21% larger than that of whole stand.关键词
