摘要 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F9代重组自交系(Recombinantinbred line,RIL)群体的穗粗、穗长、轴粗和穗重共4个穗部性状,对这4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。该结果为控制这4个性状的数量性状位点(Quanti-tative trait locus,QTL)的作图研究提供了田间表型数据。 Ear diameter, ear length, axis diameter and ear weight of maize （Zea mays L.） inbred lines ‘Mol 7＇, ‘Huangzao 4＇and the F9 Recombinant Inbred Line （RIL） population derived from the cross between ‘ Mo 17＇ and ‘ Huangzao 4＇ were investigated. According to the data of the RIL population, descriptive statis tics, correlation analysis and frequency distribution graphs of the four ear characters were performed with SPSS11.5 software. The results provided the phenotypic data for quantitative trait locus （QTL） mapping of the four ear characters.
