摘要
以半蔓生型品种洮绿218和直立型品种吉绿10号为亲本配制杂交组合,采用主基因+多基因混合遗传模型分析方法,分别以每个夹角(ob1)和每个单株夹角平均数(ob2)为研究对象,对该组合6世代遗传群体(P_1、P_2、F_1、F_2、B_1和B_2)的分枝角度进行遗传分析。结果表明,两种情况下分枝角度均受2对加性-显性-上位性主基因+加性-显性多基因控制(E-1模型)。ob1情况下,分枝角度主要受2对主基因的影响,ob2情况下,分枝角度受到2对主基因和多基因共同影响。因此,在绿豆株型育种中要综合考虑主基因、多基因和环境因素的影响。
The six generati0n p0pulations（P1, P2, F1, F2, B1 and B2） were produced from a cross between semi-erectvariety ＇Taolyu 218＇and erect variety ＇Jilyu 10＇to analyze inheritances of branch angle in mungbean by mixed ma-jor gene plus polygene inheritance model based on data of every branch angle（ob1） and average branch angle perplant（ob2）, respectively. The results showed branch angles were both dominated by two pairs of major gene with ad-ditive-dominance-epistasis effects plus polygenes with additive-dominance-epistasis（E-1 model）. The ob1 wasmainly affected by two major genes. The ob2 was both affected by two major genes and two polygenes. The role ofmajor genes, polygenes and environmental conditions should be comprehensively considered in plant type breedingof mungbean.
