摘　　要：1BL/1RS易位系在小麦高产育种中的广泛利用,对提高我国小麦品种抗病性、丰产性和稳产性起了重大作用。然而,1BL/1RS易位系的过度利用也是导致我国小麦面筋品质变劣的主要原因之一。用我国秋播麦区的主栽品种和高代品系(试验Ⅰ)、中国优质面包小麦中优9507的杂交后代中优9507×晋麦45F5代(试验Ⅱ)及澳大利亚优质面包小麦Sunstate的杂交后代Sunstate×济南16F2代(试验Ⅲ),研究了1BL/1RS易位在中国的分布及对小麦面筋品质的影响。结果表明,在251份供试品种和高代品系中,1BL/1RS易位占44 6%。1BL/1RS易位主要影响和面时间、耐揉性和弱化值等主要反映小麦面筋质量的性状,使面筋品质显著降低,而对反映面筋数量性状的蛋白质含量的影响较小。1BL/ 1RS translocation lines were comprehensively utilized in high yield breeding,which played an important role in improving the disease resistance, high production and stability of Chinese wheat.However,over usage of 1BL/ 1RS translocation lines was a major factor to cause delerious gluten quality in Chinese wheat. Three trials were designed to investigate the distribution of 1BL/ 1RS translocation lines and their effect on gluten quality. TrialsⅠincluded a collection of popularized wheat cultivars and advanced lines from Autumn-sown Wheat Zones in China. Trial Ⅱ and Trial Ⅲ were F_5 and F_2 lines from Zhongyou 9507×Jinmai 45 and Sunstate×Jinan 16, respectively. Among the 251 wheat cultivars and advanced lines 1BL/ 1RS translocation lines accounted for 44.6 %. 1BL/ 1RS translocation mainly affected gluten quality traits such as mixing time, mixing tolerance and weakness,and had little effect on protein content,a gluten quantitative trait.
