摘　　要：本研究旨在了解黄淮麦区主要栽培小麦品种的黑胚病发病情况及抗性表现。通过收集该地区33个小麦品种的种子,统计了不同品种籽粒的黑胚率、病粒率,分析了病情指数,并对其黑胚病抗性进行了分级。研究发现,不同供试小麦品种(系)黑胚率存在显著差异,各小麦品种黑胚率在6.17%~63.17%之间。‘百农607’、‘百农207’、‘山农17’、‘山农116’、‘伟隆169’和‘新麦45’的籽粒黑胚率低,病情指数轻,均为小麦黑胚病轻感类型;‘周麦36’、‘周麦28’、‘高麦6号’、‘囤麦127’、‘安科1602’和‘矮抗58’籽粒黑胚率高,病情指数重,均为小麦黑胚病高感类型。黄淮麦区不同小麦品种黑胚率存在显著差异,研究结果为该地区小麦种植提供了关于品种选择和病害管理的重要信息,有助于指导农业生产实践,减少黑胚病的发生,提高小麦产量和品质。The aim was to understand the incidence and resistance performance of black point disease in major cultivated wheat varieties in the Huang-Huai wheat region.A total of 33 wheat varieties from the region were collected,and the rates of black point kernel in grains and diseased index were statistically analyzed for each variety.Disease index was also analyzed,and the resistance to black point disease was categorized.Significant differences in the rate of black point kernel were observed among the tested wheat varieties(lines),with the rate of black point kernel ranging from 6.17%to 63.17%.Varieties such as‘Bainong 607’,‘Bainong 207’,‘Shannong 17’,‘Shannong 116’,‘Weilong 169’,and‘Xinmai 45’had low rates of black point kernel in grains and a light disease index,all were classified as having a low susceptibility to wheat black point disease;whereas‘Zhoumai 36’,‘Zhoumai 28’,‘Gaomai 6’,‘Tunmai 127’,‘Anke 1602’,and‘Aikang 58’had high rates of black point kernel in grains and a heavy disease index,all were classified as having a high susceptibility to wheat black point disease.There were significant differences in the rate of black point kernel among different wheat varieties in the Huang-Huai wheat region.The research results provide important information for variety selection and disease management in the region,which will help guide agricultural production practices,reduce the occurrence of black point disease,and improve wheat yield and quality.
