【摘要】 为了解黄淮南片近几年小麦品种对5种主要病害抗性水平，利用2017—2021年国家小麦良种联合攻关黄淮南片生产试验数据，对其成株期病害鉴定结果进行统计分析，并对中抗以上品种(系)亲本组合进行系谱分析。结果表明，黄淮南片麦区38个品种(系)对条锈病和叶锈病抗性水平较好，中抗及中抗水平以上材料占比分别为21.1%、10.5%;无高抗白粉病和赤霉病品种(系);缺少抗纹枯病品种(系);兼抗和多抗品种(系)较少，占比分别为5.3%、2.6%。对中抗及以上水平品种(系)系谱分析发现白粉病抗原较为单一，赤霉病和锈病抗源较为广泛。更多还原

【Abstract】 In order to understand the resistance level of wheat varieties to five main diseases in the south Huang-Huai region in recent years, the data of production test from 2017-2021 of south Huang-Huai were used, the results of disease identification at adult-plant stage were statistically analyzed, and the pedigree analysis of the parent combinations of varieties(lines) with medium resistance or above was carried out. The results showed that 38 wheat varieties(lines) in the south of Huang-Huai region had good resistance to stripe rust and leaf rust, and the proportion of materials with medium resistance and above medium resistance were 21.1% and 10.5%, respectively. There was no high resistance to powdery mildew and fusarium head blight, lack of resistance to sheath blight varieties(lines). There were fewer varieties(lines) with concurrent resistance and multiple resistance, accounting for 5.3% and 2.6%, respectively. Pedigree analysis of varieties with moderate resistance and above showed that resistance sources of powdery mildew were single, but were extensive to fusarium graminearum and rust.更多还原
