INHERITANCE AND MODIFIED EFFECTS OF BRACHYTIC GENES IN SOYBEANS-文献传递-植物通论文库

摘要：矮源矬大豆的矮秆性状表现受一对隐性主效基因和若干修饰基因所控制。在较高 F_2植株间株高表现连续变异。F_2频率分布的高峰和变幅都向较矮方向漂移和扩大,其程度不仅受改良亲本株高基因的影响,还受其结荚习性基因的作用。矮秆基因对降低株高,缩短节间长度,提高每节荚数、收获指数、抗倒伏性和其它产量性状都有一定效果。具

Abstract:1.The data of F_1 and F_2 in four crosses between dwarf germplasm‘Cuo-dadou’(P_1)and four different high-yielding improved parents(P_2)and X~2 test results indicated that inheritance of brachytic character wascontrolled by one pair major recessive gene and some modifying genes.Plant height among t
