摘　　要：为了解黄淮麦区小麦品种资源在江苏淮北地区的品质表现并筛选适于江苏淮北地区种植的优质小麦品种,利用多功能近红外分析仪检测了296份小麦品种的品质。结果表明:面团形成时间、稳定时间和面粉沉淀值的变异系数较大,而籽粒容重、出粉率和面团吸水率的变异系数较小。籽粒蛋白质含量与湿面筋含量、沉淀值、形成时间、稳定时间呈极显著正相关;容重与湿面筋含量呈极显著负相关。聚类分析将品种分为5类群,其中第Ⅰ类群集中了大部分强筋品种,第Ⅱ类群大部分为中筋品种,第Ⅳ类群为弱筋。陕西、河南、江苏和安徽选育品种在品质性状上有显著差异。通过对全部品种各项指标进行筛查,40份品种符合强筋优质标准,其中河南17份、江苏11份、陕西10份、安徽2份。In order to analyze the wheat quality and screen for high quality varieties for Huaibei area of Jiangsu province,296 wheat varieties from Huang-Huai region were analyzed by near-infrared spectroscopy technology.The results showed that the coefficients of variation were larger in development time,sedimentation value and stability time,while the coefficients of volume weight,flour yield and water absorption were smaller.There were significantly positive relationships between kernel protein content and wet gluten content,sedimentation value,development time,stability time at 0.01 level.There were significantly negative relationships between volume weight and wet gluten content.Using an appropriate combined line,the 296 varieties were divided into 5 groups.GroupⅠconcentrated most of the varieties with strong gluten,and groupⅡincluded most of medium gluten varieties,groupⅣwere weak gluten varieties.There were significant differences among Shaanxi,Henan,Jiangsu and Anhui provinces in quality properties of wheat.Through screening of indicators in all varieties,40 varieties were suitable for strong gluten wheat,in which,17 from Henan,11 from Jiangsu,10 from Shaanxi and 2 from Anhui.
