摘要: 本实验利用三点测交分析的方法, 对3个组合在人工接种大豆灰斑病菌的条件下的抗性表现进行基因效应分析,各组合均存在加性,组合1存在显性,组合2、3存在上位性。
Abstract:In this paper,Triple Test Cross Design was used in studing the resistance of soybean to 10 physiological race of Cercospora Sojina Haraby inoculation.Results o analysis of gene effects of resistance indicated that additive effect is significant in all the three crosses,dominant effect exsists only in the cross 1 and epistatic effect remains in the cross 2 and cross 3.
