摘　　要：蚕豆赤斑病是世界上蚕豆生产区的重要病害,我国蚕豆赤斑病主要危害东南沿海及长江流域蚕豆产区,常造成严重产量损失。本研究对146个蚕豆种质资源连续3年进行了抗赤斑病田间自然发病鉴定和离体叶片接种鉴定。田间鉴定结果表明,146个参试材料中有抗病(R)材料8个,分别是‘TC-1’‘YC-1’‘YC-2’‘YC-3’‘YC-4’‘通180501’‘通蚕鲜8号’和‘通20606’,中抗(MR)材料49个,感病(S)材料77个,高感(HS)材料12个。离体接种鉴定结果表明,146个参试材料中有中抗(MR)材料28个,感病(S)材料80个,高感(HS)材料38个。综合田间自然发病和离体叶片人工接种鉴定结果,表现为中抗及以上水平的材料有24个,可以这些材料为基础开展蚕豆抗赤斑病育种。Chocolate spot is an important disease impacting faba bean production in the world,particularly in the main production regions along the southeast coast and the Yangtze River Basin in China,often causing serious yield losses.In this study,a total of 146 faba bean germplasm resources were evaluated for resistance to chocolate spot natural field infection and detached leaf artificial inoculation during 2020 to 2023.Field assessments showed eight resistant(R)germplasms,namely‘TC-1’‘YC-1’‘YC-2’‘YC-3’‘YC-4’‘Tong180501’‘Tongcanxian 8’and‘Tong20606’.Additionally,49 germplasms were moderately resistant(MR),77 were susceptible(S)and 12 were highly susceptible(HS).The artificial inoculation test indicated 28 germplasms as moderately resistant(MR),80 as susceptible(S),38 as highly susceptible(HS).Based on the results from both natural field infection and artificial inoculation,24 germplasms demonstrated resistance(R)or moderate resistance(MR)and could serve as foundational resources for breeding faba bean varieties resistant to chocolate spot.
