大豆育种方法与技术

Methods and techniques of soybean breeding

从大豆育种的管理角度,分析了大豆的育种实验选择,提出选择合适的试验场地和优良的种子亲本,并加强对后代的筛选管理。介绍了大豆的系统育种、杂交育种、辐射育种等三种方式,阐述了大豆育种的管理过程,提出加强大豆育种的性状选择,包括大豆株型的选择,茎杆与叶形的观察,茎杆方面的选择和根系方面的选择,以培育出更加优良的品种,为提高大豆育种的技术水平提供重要支持。

From the perspective of soybean breeding management,this paper analyzes the selection of soybean breeding experiments,proposes to select suitable test sites and excellent seed parents,and strengthen the screening management of offspring. This paper introduces three ways of soybean breeding: systematic breeding,cross breeding and radiation breeding,expounds the management process of soybean breeding,and puts forward to strengthen the character selection of soybean breeding,including the selection of plant type,the observation of stem and leaf shape,the selection of stem and root system,so as to cultivate better varieties and provide important information for improving the technical level of soybean breeding support.
