| 摘 要： | 利用１７个玉米优良自交系，配成完全双列杂交，以杂种优势距离为指标，为１７个亲本进行了聚类分析，结果表明，１７个自交系可分成六类优势群，群间具有较大优势，聚为结果与自交系的亲缘关系一致。另外，本文初步研究了玉米的杂种优势模式。

| Abstract: | Cluster analysis was done based on heterotic distance from diallel crosses of seventeen elite maize inbreds lines. The results showed that the seventeen lines can be divided into Six heterotic groups that were accorded with relevant parentages, Besides, preliminarlly heterotic model of maize was studied. |

| Keywords: | maize inbred line diallel crosses cluster analysis heterotic group |
