| 摘 要： | 苏951是江苏省农业科学院粮食作物所选育的优良玉米自交系，利用苏951已经育成一批优良组合。根据玉米杂种优势群和杂种优势模式，按不完全双列杂交模式组配了20个杂交组合，对苏951的一般配合力和特殊配合力进行分析评价苏951的育种特性。研究结果表明：除穗行数外，苏951的大部分产量性状的一般配合力较高，与塘四平头群、PN群有较强的杂种优势。

| Abstract: | Su951 is one of the super maize inbred lines, and was developed by the institute of food crops, Jiangsu academy of agricultural sciences. A number of fine hybrids had been bred by combining with Su951. According to the heterotic groups and heterotic patterns, the general combining ability(GCA) and specific combining ability(SCA) of Su951 were evaluated with 20 hybrid combinations that were grouped by incomplete diallel cross model. The results showed that GCA of most traits of Su951 was excellent except for that of rows per ear. Su951 is a stronger heterosis than Tangsipingtou and PN group. |
