摘要：对来自3个省的58个毛红椿家系在安徽南陵进行了造林试验。3年生幼林的生长结果表明,毛红椿的树高、胸径2个性状在家系间均存在极显著差异;树高、胸径2个性状在不同重复间表现出极显著差异;毛红椿幼林期树高和胸径2个性状变异系数分别为21.1%和28.8%,其变异比较丰富,树高、胸径2个性状具有中等以上的广义遗传力。以树高和胸径为选择对象,选择出10号、15号、19号、27号和39号等5个在幼林期表现较为优异的家系。
An affforestation trial of Toona ciliata var.pubescens containing 58 families was conducted in Nanling,Anhui Province.The results showed that the differences of these growing characters were significant between families.Variation coefficients of tree height and breast height diameter were 21.1% and 28.8%,respectively.This indicated that the variation in growing traits was very rich.The broad heritability of tree height and breast height diameter was above the middle level.Fast-growing families were selected according to the growing traits of the young forests,they are No.10,No.15,No.19,No.27 and No.39.
