摘　　要：通过对17个多小穗小麦品系的7个农艺性状的研究,分析多小穗小麦籽粒蛋白质含量变化规律及株高、千粒重、籽/杆、小穗数、干/鲜、旗叶面积、有效分蘖与其蛋白质含量间的关系。结果表明:7个性状对蛋白含量的影响均不高,株高和籽杆比两个农艺性状对多小穗小麦籽粒蛋白质含量的影响相对较大,说明小麦籽粒蛋白含量是一个多因素影响的变量。而多小穗小麦籽粒蛋白质含量随着灌浆时间的延长含量呈现出"V"字型变化。The relationship of agronomic traits and the grain protein content were analyzed by 7 traits of 17 strains of multi-spikelet wheat.The 7 traits were plant height,grain wheat,seed/bar,small ears,dry/fresh,flag leaf area and productive tiller respectively.The results showed that the effect of 7 traits on the protein content was not conspicuous,the plant height and seed/bar affected relatively more grain protein content of multi-spikelet wheat,and wheat grain protein content was a multi-factors variable.While the grain protein content of multi-spikelet wheat displayed a shape of ＂V＂ during filling stage.
