选用１４个冬小麦品种，按ＮＣⅡ设计配制４５个杂交组合，采用配合力分析→主成分分析→灰色关联度分析的方法，综合了亲本产量性状配合力分析的信息，突出了主要因素，简化了亲本评价指标，并论证了把一般配合力剖分为品种效应和品种优势效应对指导亲本选配的意义，指出选配强优势组合，要求亲本综合品种优势大并能很好地互补。结果表明，新冬１５号是较理想的亲本，其次为８４（１７）、８０－４５３、衡水８１１６、８０１８２、Ａｓｏｓａｎ和套花１号。 Fourteen winter wheat cultivars were selected and 45 hybrid combinations were designed according to NC Ⅱ design. Combining ability analysis, principal component analysis and gray relational analysis were used to analyze the combining ability of parent yield traits. The main factors were highlighted and the parents were simplified Evaluation index, and demonstrated that the general combining ability is divided into variety effect and variety superiority effect on the selection of guiding parents. It is pointed out that the selection of strong dominant combination requires that the parent variety has great advantages and can complement each other well. The results showed that Xin Dong 15 was the ideal parent, followed by 84 (17), 80-453, Hengshui 8116, 80182, Asosan and Qiahua 1.
