摘 要 ：以４年对不同小麦品种的赤霉病为害损失结构的研究为基础，用９５０个数据构建了小麦赤病的产量，质量损失模型，结果表明，单穗粒重损失率是唯一完全的，最佳的产量损失指标，千粒重损失率是粗略的产量损失估计指标。病粒率是品质损失的最佳指标，用其可完整地表征赤霉病的产量，质量损失。

Abstract:The loss models of yield and quality were constructed based on loss composition of yield and quality cased by wheat scab in different wheat cultivars with data collected in 4 years. The results showed that loss rate of kernel weight per spike was the only
