通过对１０个参测品种的抗性测定表明，秀水系统品种对稻瘟病抗性相对稳定，从品种育成时期上可分为３个抗性层次：（１）７０年代育成的品种以秀水４８为代表仅对中Ｆ１等小种表现抗性；（２）８０年代育成的品种如秀水０４等对中Ｄ、中Ｅ、中Ｆ群等小种的大部分菌株表现抗性；（３）９０年代育成的品种如秀水１７能抗包括中Ａ群在内的大部分菌株。部分品种在一些地区发病较重，系田间病菌小种变化所致。 The resistance of 10 tested varieties showed that the resistance of Xiushui system to rice blast was relatively stable, and it could be divided into 3 resistance levels from the breeding period of cultivars: (1) The cultivars cultivated in the 70's with Xiushui 48 Representing only resistance to race F1 and other races; (2) breeding varieties in the 1980s such as Xiushui 04 and other strains of D, E, F group showed resistance to most strains; (3) 90's Bred varieties such as Xiushui 17 resistant to most strains, including the A group. Some species in some areas of severe disease, Department of bacteria caused by bacterial species changes.
