一、前言我省是杉木主要产区,产量居全国首位,但,目前一般产量仍很低,而且悬殊很大。为了迅速提高杉木产量,我省早在六十年代开始选择大批杉木优树;然而,杉木优树是依据表型性状选择的,而优树的表型是其遗传因子与环境条件综合作用的结果。这种表型是遗传因子或环境作用(位置效应)决定呢?其强度和适应性如何,这就需要对优树进行表型测定。通过测定,可以优中选优,使我们有可能从中选择遗传力高、增益大的优树,加以大量(无性或有性)繁育,以加快改良杉木的目的。为此,我们于78年开始在邵武卫闽林场进行部分的杉木优树子代测定。
First, the preface Our province is the main producing areas of fir, the output ranks first in the country, but the current general production is still very low, but the great disparity. In order to rapidly increase the production of Chinese fir, the province started to select a large number of excellent Chinese fir trees as early as the 1960s. However, the optimal selection of Chinese fir is based on the phenotypic traits, while the superior tree phenotype is the result of the combination of genetic factors and environmental conditions . This phenotype is determined by genetic factors or environmental effects (location effects), and its intensity and adaptability, which requires the phenotypic determination of elite trees. Through the determination, we can select the best and the best, so that we may choose from heritability, high gain of the tree, to a large number (asexual or sexual) breeding, in order to accelerate the purpose of improving the Chinese fir. To this end, we started in the Shaowu Wei Min Forest Farm part of the fir seed progeny determination in 78 years.
