近几年来,我国林木良种选育工作蓬勃开展,各地选出了大量优良单株,建立了不少种子园。如何对这些优树和种子园的子代进行鉴定,以确定其是否具有优良的遗传特性,从而提高选择效果,是当前迫切需要解决的问题。福建省洋口林场在南京林产工业学院的协助下,1964年以来,就开展杉木选优,建立种子园和子代鉴定工作。本文,就是他们十几年来杉木子代鉴定的经验总结。这篇文章详细介绍了杉木优树子代鉴定的田间设计、生物统计、效果分析等各种作法及子代鉴定的效果,对其他地区有一定参考价值。子代鉴定是项新的工作,希望各地根据各自的具体情况,因地制宜地积极开展这项工作,总结经验,提出更多、更好的子代鉴定方法,提高我国林木遗传育种的理论基础,把林木良种选育工作推向更高的水平。
In recent years, vigorous breeding of forest trees in our country has been vigorously carried out. A large number of excellent single plants have been selected and many seed orchards have been established. How to identify the progeny of these elite trees and seed orchards to determine whether they have excellent genetic characteristics and thus improve the selection effect is an urgent problem to be solved. With the assistance of Nanjing Forestry Industry College, Yangkou Forestry Station of Fujian Province, since 1964, has conducted the selection of Chinese fir seed and the appraisal of seed orchards and offspring. This article, is their experience in appraisal of offspring fir more than a decade. This article describes in detail the field design, biometrics, effect analysis and other methods of identification and progeny identification of the excellent seedlings of Chinese fir, and provides some reference value to other regions. The identification of offspring is a new job. We hope that all localities will actively carry out this work according to local conditions according to their specific conditions, sum up their experiences, come up with more and better appraisal methods for offspring, and raise the theoretical basis of tree breeding in our country. Forest seed breeding work to a higher level.
