摘　　要：[Objective] This study aimed to provide a theoretical basis for the genetic improvement of maize quality in Shanxi Province. [Method] The variations in unit weight, crude starch content, crude protein content, crude fat content and lysine content of maize cultivars approved by Shanxi Province during 2003-2012 were analyzed. [Result] In Shanxi Province, the average unit weight and crude starch content of maize cultivars approved during 2003-2012 were trended to be increased;the crude fat contents of maize cultivars approved during 2003-2012 showed no significant changes; the lysine contents of maize cultivars approved during 2003-2008 were essentially unchanged; the crude protein contents of maize cultivars approved during 2003-2012 declined slightly. [Conclusion] The crude starch content and unit weight of maize increased with the increased yield; the crude protein content, crude fat content and lysine content showed certain stability, and they were mainly controlled by genes. Therefore, the breeding of particular maize should be strengthened.[目的]为山西玉米的品质遗传改良提供理论依据。[方法]对2003～2012年山西省审定玉米品种的容重、粗淀粉、粗蛋白、粗脂肪及赖氨酸含量的变化进行分析。[结果]2003～2012年山西省审定玉米品种的平均容重和粗淀粉含量有升高的趋势;2003～2012年山西省审定玉米品种的粗脂肪含量基本无变化;2003～2008年山西省审定玉米品种的赖氨酸含量基本无变化;2003～2012年山西省审定玉米品种的粗蛋白含量略有下降。[结论]粗淀粉含量和容重随玉米产量的提高而提高,而粗蛋白含量、粗脂肪含量的赖氨酸含量等指标具有相对的稳定性,主要由遗传基因所控制,因此必须加强专用型玉米选育。
