摘　　要：用9个郑58的株系为母本,昌7-2为父本组配了9个近缘组合,以郑单958为对照,分析了近缘组合的性状差异及其与产量的关系。结果显示,各近缘组合农艺性状间存在差异,在株高、穗位高、茎粗、SPAD值等性状上,多数组合均优于对照,但单株叶面积则表现出减少的趋势。通过亲本株系的选择,可以改良原杂交种的农艺性状。Zhengdan 958（control） and 9 hybrid combinations which were made by 9 related inbred lines of Zheng 58 （M） and Chang 7-2 （F） were used in this experiment to analysis correlations of their traits and yield. The result showed that comparison with the control, 9 hybrid combinations＇ agronomic characteristics were different. Most of the related hybrid combinations＇ plant height, ear position height, stalk width and SPADR were better than these of the control, while the leaf area per single plant was lower than that of control. The agronomic characteristics of combination could be improved by the selection of related inbred lines.
