树木育种工作,在林业建设中很为重要。我国树木育种工作历史不长,选择优树多采用优势木比较法,即本文所谓比较木法。针叶树育种,如杉树选优,采用的是比较木法,近来,阔叶树育种,如桉树选优,也采用比较木法,选优标准,未因树种各别。本文提出用数理统计学方法,分析研究优树后代的遗传效益,认为某些树种用比较木法,不及单株选择法。这里刊载的译文,因篇幅有限,对原文作了极大的删节,有条件时,盼参阅全文。对本文提出的问题,希望引起重视。
Tree breeding work in the construction of forestry is very important. The history of tree breeding in our country is not long, choose the superior tree to use the superior wood comparison method, which is the so-called comparative wood method. Conifers breeding, such as cunninghamii preferred, using a comparative wood method, recently, broad-leaved tree breeding, such as eucalyptus selection, but also using comparative wood, selection criteria, not due to different species. In this paper, we propose to use mathematical statistics to analyze the genetic benefit of elite offspring. We think that some tree species are better than the single tree selection method. The translations contained here have been greatly abridged from the original due to limited space. When possible, we hope to see the full text. The problems raised in this paper, I hope to attract attention.
