作物遗传育种中多元遗传分析的研究与应用

Research and Application of Multivariate Genetic Analysis in the Field of Crop Genetics and Breeding

本文在大量文献资料基础上,概述了多元遗传分析研究的由来与发展、现状和趋势,着重阐明了它在作物遗传育种领域中的地位和作用,并对存在的问题作了讨论.

The author hold the point of view that the multivariate genetic analysis is to apply the multivariate statistical analysis methods onto the study of genetic problems of quantitative traits in the field of crop genetics and breeding. The methods include cluster analysis, princiapal components analysis, canonical correlations analysis and factor analysis, etc. The author, based on the documents of multivariate genetic analysis, summarized of its current situation and developing tendency, and discussed the problems existed. It is believed that the multivariate genetic analysis could play a very important role in the field of crop genetics and breeding.
