本研究调查了玉米自交系Mo17、黄早4及由这两个材料构建的F_9代重组自交系(Recombinant inbred line,RIL)群体的株高和穗位高两个株型性状,对这两个性状在群体中的表现用SPSS11.5软件作了描述性统计和相关分析,并构建了频数分布图.结果显示这两个性状在亲本间表现出显著差异;在群体中呈现连续变异,与正态分布曲线拟合较好.该结果为控制这两个性状的数量性状位点(Quantitative trait locus, QTL)的作图研究提供了田间表型数据.

Plant height and ear height of maize (Zea mays L.) inbred lines 'Mol7', 'Huangzao 4' and the F9 recombinant inbred line (RIL) population derived from the cross between 'Mol7' and 'Huangzao 4' were investigated in this study. According to the data of the RIL population, descriptive statistics, correlation analysis and frequency distribution graphs for the two plant type characters were performed with SPSS 11.5 software. The results showed that the two traits were significantly different between the two parental lines, and continuous variations were found in the RIL population. The results provided the phenotypic data in QTL mapping controlling the two plant type characters.
