对玉米品种先玉335和改良先玉335及亲本进行玉米大斑病田间最大病斑平均面积和病情指数的动态模拟分析，得到病斑面积和病情指数的曲线图和逻辑斯蒂模型。结果表明，改良先玉335及其亲本在对玉米大斑病的抗性上优于先玉335及其亲本。根据逻辑斯蒂模型分析，先玉335在本地区种植防治玉米大斑病的最佳时期是7月27日前。
對玉米品種先玉335和改良先玉335及親本進行玉米大斑病田間最大病斑平均麵積和病情指數的動態模擬分析，得到病斑麵積和病情指數的麯線圖和邏輯斯蒂模型。結果錶明，改良先玉335及其親本在對玉米大斑病的抗性上優于先玉335及其親本。根據邏輯斯蒂模型分析，先玉335在本地區種植防治玉米大斑病的最佳時期是7月27日前。

The research on dynamic simulation analysis of average field maximum lesion area and disease index of the breed Xianyu335, improved Xianyu335 and the parent was conducted, the curve diagram and logic of Chris-tian's model of lesion area and disease index were got. The results showed that the resistance to maize leaf blight of improved Xianyu335 and its parents were higher than the that of original Xianyu335 and its parents, according to the logical analysis of Christian model, the optimal period of controlling this disease in the local area of Xianyu335 was before July 27th.
