| 摘 要： | 选用不同杂种优势类群且系谱明确的五个自交系为测验种,采用NCⅡ试验设计,对十三个优良玉米自交系进行杂种优势类群分析研究,通过聚类分析,把十三个玉米自交系划分为四个杂优类群,分别为：Lan-caster群（NH-14、Spx3、Dx37）;改良Reid群（LN-2）;唐四平头群（LN-15、Spx56、Dx321）;旅大红骨群（红轴598、DY112、LD61、DY45）;KS75和KSt12难以与其它自交系或彼此间归为一类。

| Abstract: | The research of a NCII design experiment for heterosis groups of thirteen exceptional maize inbred lines by Selecting the different heterosis groups and the pedigree of five inbred lines tester,thirteen maize inbred lines are divided into four heterosis groups through the cluster analysis,The result is as follows： Lancaster group（NH-14,Spx3,Dx37）;Reid group（LN-2）;Tangsipingtou group（LN-15,Spx56,Dx321）;Lvdahonggu group（red-axis598,DY112,LD61,DY45）;KS75 and KSt12 are difficult to and other inbred lines from delivering heterosis groups into one among each other of them. |
