摘要
林木遗传育种进程中,有一个高世代遗传选择与育种的过程。在这个过程中,不同种类与不同性质的树种有着各自不同的特点。乔木、灌木、针叶、阔叶、用材、经济等等树种在进入高世代育种过程中,都会遇到一些具共性或特殊性的问题。本文以马尾松为例,基于对贵州马尾松遗传育种几十年的工作经验及出现的问题,提出高世代育种应该将多世代选择育种、多目标育种、种内(间)杂交育种、特异形状选择等贯穿于全过程中;提出完备的遗传育种研究体系中4个组成部分(4个群体)完整协调组建的重要性。通过这些工作,尽可能多的为不断推进的林木遗传育种研究与实践提供科学有效的物质基础与技术储备。
in the process of genetic breeding of forest trees,there exists a technique of the genetic selection and breeding of the advanced generation,during which different species or different types of trees have different characteristics. In view of this,based on the working experience and the existing problems over the past several decades,this paper suggested that following techniques be carried out throughout the course of advanced generation breeding：multiple generations selection breeding,multi- objective breeding,inter- or intra- species hybrid breeding,specific traits selection,etc. These will provide material and technical basis for genetic breeding of forest trees in the future.
