摘    要:在传统的数量性状多基因遗传模型基础上提出主基因-多基因遗传模型具普遍性,纯主基因或纯多基因遗传模型只是其特例。由此初步建立了植物数量性状遗传体系分离分析方法。目前该方法可以检验2~3个主基因的个别遗传效应、多基因整体的遗传效应和两者的遗传率。本文介绍这种分离分析方法的研究经过、主要进展及应用效果,并以实例说明其分析步骤、方法和效果。

关 键 词:分离分析  主基因-多基因遗传模型  植物数量性状

Abstract:Based on the traditional polygene inheritance model of quantitative traits, the mixed major gene and polygene inheritance model was raised and considered as the general model, while pure major gene or pure polygene inheritance model being only the specific case of the general model. From the proposed theory, the segregation analysis procedure was established for studying the genetic system of quantitative traits of plants. At present this procedure can be used to evaluate the genetic effects of individual major genes (up to 2-3 major genes) and the collective genetic effects of polygenes as well as their heritability values. The present paper introduces the process of the establishment of the procedure, main achievements and application results. An example was given to illustrate the steps, methods and effectiveness of the procedure.
Keywords:quantitative traits of plants  mixed major gene and polygene inheritance model  segregation analysis
