| 摘 要： | 为筛选高抗瓜类细菌性果斑病的西瓜资源，以24份西瓜品种资源为试材，采用苗期喷雾接种法分别接种分离自甜瓜上的瓜类嗜酸菌Acidovorax citrulli菌株pslb96和ZZ-1，鉴定各品种资源对瓜类细菌性果斑病的苗期抗性。结果表明，24份西瓜品种资源中未发现有对2株菌株表现免疫的材料，有7份资源对菌株pslb96表现高抗，12份资源对菌株ZZ-1表现高抗；9份资源对菌株pslb96表现中感或感病，7份资源对菌株ZZ-1表现中感和感病；对2株菌株均表现高抗的品种资源有野生型种质资源A9及商品种华欣、申蜜968、申选958和申抗988，占总品种资源的20.83%。部分品种资源A4、A13和申蜜7号对菌株pslb96和ZZ-1的抗性表现出明显的差异，表明相同寄主来源的2株不同菌株致病力存在差异。

| Abstract: | In order to screen watermelon varieties resistant to bacterial fruit blotch(BFB), caused by Acidovorax citrulli, 24 watermelon varieties and germplasms were inoculated with strains of A. citrulli,pslb96 and ZZ-1, derived from maskmelon through a seedling-spraying method. The results showed that out of the 24 varieties or germplasms tested, none were immune to the pathogenic strains; seven and 12 cultivars were highly resistant to pslb96 and ZZ-1, respectively; while nine and seven was susceptible to pslb96 and ZZ-1, respectively. Total five watermelon materials, accounting for 20.83%, including a germplasm, A9 as well as four cultivars, Huaxin, Shenmi 968, Shenxuan 958 and Shenkang988, showed high resistance to both pslb96 and ZZ-1. Three varieties A4, A13 and Shemmi 7 showed much different responses to pslb96 and ZZ-1. The results indicated that the pathogenicities of the two strains derived from same host are different. |
