The most important was to continue filling the relative parasitic fitness database.
重要的是需要继续充实寄生适合度数据。
Relative parasitic fitness was detected on suscepitable wheat cultivars Mingxian 169 for mutants of the CY17 and CY31, and disease capacity was used in the experiment.
测定了CY17，CY31突变菌系在感病品种铭贤169上的相对寄生适合度属性，并利用“病害量”衡量突变菌株的相对寄生适合度。
