摘要： 利用抗源亲本与园艺性状优良的非抗源亲本进行品种间人工杂交。根据5个杂交组合调查结果表明:菜豆抗锈遗传F₁抗病性为显性;有3个组合的抗病性受一对基因控制,F₂抗与感按3:1比例分离,另二个组合F₂抗与感按15:1或63:1比例分离,其抗病性是受两对或三对基因控制的。从80-2×30-7组合中选育出“新秀1号”和“新秀2号”抗锈新品种,表现垂直抗性。从80-4×12号玉豆组合中选育出87-2-8-1,87-1-33-2,87-1-18-2-3属于水平抗性。这些抗锈新品种（系）在秋季莱豆锈病大流行季节种植,表现出明显的增产增收效果。

Abstract: Crossing was made between resistant parents and early-matur-ing, high-yielding, non-resistant parents, Phenotypes of the F1 generation and the ratio of resistant plants to susceptible plants in the FZ generation were investigated,Dominant resistance was found in F}.The FZ segregated either at the ratio of 3:1，indicating the presence of a single resistant gene，or at the ratio of 15:1 or 63:l，indicating the presence of 2 or 3 dominant genes, Two new lines-L ine 86-9-1 (Yinxiu 1)and Line 86-9-4 (Yinxiu 2)-were selected from the combination 80-2x30-7 and tested for reactions to physiological races of Bean Rust collected from seven different areas, Results showed that these two lines were highly resistant to the dominant but susceptible to race +Tianjin 1136"，indicating that these two lines were vertically resistant, "Three lines, i,c,87-2-8-1，87-1-33-2 and 87-1-18-2-3, selected from combination of 80-4 x yudou No, 12 were moderately resistant to dominant, physiological races from seven areas and race"Tianjin 1136"，demonstrating that the new lines were horizontally resistant.All the lines increased yield remarkably during the epidemic season of the Bean Rust disease.
