| 摘 要： | 试验是采用6份外引玉米种质资源选育的自交系与国内5大类群的5个自交系进行不完全双列杂交,并用超高优势值和超中优势值进行杂种优势分析,以明确这6份玉米自交系与所属的5大类群之间的杂优模式,研究结果表明：自交系C-1、C-2、C-3与旅大红骨类群、自交系C-1与Reid类群、自交系C-6与Lancaster和PN78599类群间在产量上有比较强的杂种优势,与这些类群杂交很容易出现高产组合,可以直接应用于实践,建立新的杂优模式。

| Abstract: | Usng six inbred lines which selected from exotic germplasm resources and five inbred lines representing five local groups as parent lines and thirty combinations were obtained by the method of incomplete diallel cross.In order to definite the heterotic pattern of six inbred lines with the five groups,we made an analysis of the heterosis using ultra high dominating value and ultramiddle dominating value.The results indicated inbred lines C-1,C-2,C-3 with Lvda Red Cob group,C-1 with Reid group and C-6 with La... |
