摘　　要：将 2组共计 185个国内外小麦品种分别在 4种和 2种环境条件下种植 ,分析其淀粉特性的遗传变异及其与面条品质的关系。结果表明 ,小麦品种淀粉特性变异幅度较大 ;淀粉特性较好的国外品种 (系 )有Sunstate、Hartog、Eradu、Cunninghan、Gamenya、Karl92和Sunco ,淀粉品质较好的国内品种有扬麦 5号、扬麦 15 8、绵阳 2 6、鄂恩 1号、豫麦 4 1、豫麦 4 9、郑 81 1、豫麦 5 4、豫麦 2号、豫麦 4 7、鲁 95 5 15 9、鲁麦 15、鲁麦 2 1、陕优 2 2 5、关封 2号、冀5 0 99、北农 4号和津麦 2号等 ;国外品种、南方麦区和黄淮麦区品种的淀粉特性和面条品质较好 ,北部冬麦区品种则较差 ;峰值粘度、稀懈值和面粉膨胀体积是衡量淀粉品质和面条品质的 3个重要指标 ;我国品种中Wx B1缺失频率较高 。wheat cultivars from major wheat producing regions in China, Australia and USA in two trials were sown in four and two environments, respectively, to investigate starch properties of wheat cultivars and their relationship with dry white Chinese noodle (DWCN) quality. Significant differences were observed in starch properties and DWCN quality. Wheat cultivars such as Sunstate, Hartog, Eradu, Cunninghan, Gamenya, Karl92, Sunco, Yangmai5, Yangmai158, Mianyang26, E'en1, Yumai41, Yumai49, Zheng81 1, Yumai54, Yumai2, Yumai47, Lu955159, Lumai15, Lumai21, Shanyou225, Guanfeng2, Ji5099, Beinong4 and Jinmai2 performed high pasting viscosity. Wheats from Australia, USA, South China Autumn sown Spring Wheat Region and Yellow and Huai Valley showed better starch properties and DWCN quality than wheats from Northern China plain. High peak viscosity, breakdown and flour swelling volume were significantly associated with good DWCN quality. A high frequency of Wx B1 null alleles was detected in Chinese wheats. Cultivars with null for Wx B1 GBSS have higher pasting viscosity and flour swelling volume, and better DWCN quality.
