The experiment is based on the quantitative traits in plants proposed by Gai Junyi major gene plus polygene mixed inheritance model, using multiple generations joint quantitative trait analysis I-P1, P2, F1, F2and F2:3conjoint analysis method, was conducted to study the inheritance of9agronomy traits and2quality traits of in soybean, the five populations, P1、P2、F1、F2and F2:3from each of three combinations (Cross Ⅰ-Lines2002×EXP、CrossⅡ-Tongnongl3×Yi3、CrossⅢ-is Jinlin47×ARIRA) were used in this study.
