    摘要:

    为掌握我国黄淮麦区主推或新近选育小麦品种对假禾谷镰孢菌(Fusarium pseudograminearum)和禾谷镰孢菌(F. graminearum)的抗性水平,采用室内苗期人工接种法和田间穗期单花滴注接种法对黄淮麦区主推或新近选育的 116 份小麦 品种进行了抗性评价。结果表明,供试小麦品种中,对假禾谷镰孢菌和禾谷镰孢菌没有免疫(I)和高抗(HR)的品种。在 室内人工接种条件下,仅有 3 个品种对假禾谷镰孢菌表现中抗(MR),占供试品种的 2.59%,表现感病(S)的品种有 10 个,占 8.62%,103 个小麦品种表现高感(HS),占 88.79%;对禾谷镰孢菌表现中抗(MR)的小麦品种有 23 个,占供试 的 19.83%,表现感病(S)的品种有 50 个,占 43.10%,43 个品种表现高感(HS),占 37.07%。在田间单花滴注接种条件 下,对假禾谷镰孢菌表现抗病(R)的品种有 6 个,占 5.17%;表现中抗(MR)的品种有 10 个,占 8.62%,表现中感(MS) 的品种有 62 个,占 53.45%,表现感病(S)有 34 个,表现高感(HS)的有 4 个品种;仅苏麦 3 号 1 个品种对禾谷镰孢菌表 现抗病(R, 0.86%),囤麦 127 和新麦 208 表现中抗(MR, 1.72%),37 个品种表现中感(MS),49 个品种表现感病(S), 表现高感(HS)的品种有 26 个。供试小麦品种对 2 种镰孢菌不同时期的抗性表现存在明显差异,苗期室内人工接种条件下, 抗假禾谷镰孢菌的品种少,而穗期单花滴注接种条件下,抗禾谷镰孢菌的品种少。

    Abstract:

    The resistance of 116 wheat varieties collected from the wheat-producing area of Huang-Huai to Fusarium pseudograminearum (Fp) and F. graminearum (Fg) was evaluated by means of artificial inoculation indoors at seedling stage and single flower instillation inoculation at heading stage in the field. Indoor evaluation results showed that none of the varieties were imunne or highly resistant against Fp and Fg. Against Fp, 3 varieties (2.59% of the total) were moderately resistant, 10 varieties (8.62% of the total) were susceptible, and 103 varieties (88.79% of the total) were highly susceptible. Against Fg, 23 varieties (19.83% of the total) were moderately resistant, 50 varieties (43.10% of the total) were susceptible, and 43 varieties (37.07% of the total) were highly susceptible. Field evaluation results showed that against Fp, 6 varieties (5.17% of the total) were resistant, 10 varieties (8.62% of the total) were moderately resistant, 62 varieties (53.45% of the total) were moderately susceptible, 34 varieties (29.31% of the total) were susceptible, 4 varieties (3.45% of the total) were highly susceptible. Against Fg, 1 variety (Sumai 3) (0.86% of the total) was resistant, 2 varieties (Tunmai 127 and Xinmai 208) (1.72% of the total) were moderately resistant, 37 varieties (31.90% of the total) were moderately susceptible, 49 varieties (42.24% of the total) were susceptible, and 26 varieties (22.41% of the total) were highly susceptible. The tested varieties showed different patterns of resistance against Fp and Fg in different stages, with relatively fewer varieties resistant against Fp than against Fg treated with artificial inoculation indoors in seedling stage, and relatively fewer varieties resistant against Fg than against Fp treated with single flower instillation inoculation in the field in heading stage.
