Abstract

Maize (Zea mays L.) is one of the most important crops in the world. In this study, 13 agronomic traits of a recombinant inbred line population that was derived from the cross between Mo17 and Huangzao4 were investigated in maize: ear diameter, ear length, ear axis diameter, ear weight, plant height, ear height, days to pollen shed (DPS), days to silking (DS), the interval between DPS and DS, 100-kernel weight, kernel test weight, ear kernel weight, and kernel rate. Furthermore, the descriptive statistics and correlation analysis of the 13 traits were performed using the SPSS 11.5 software. The results providing the phenotypic data here are needed for the quantitative trait locus mapping of these agronomic traits.

摘要

玉米（Zea mays L.）是世界上最重要的作物之一。在本研究中，对由Mo17和黄早四杂交衍生的重组自交系群体的13个农艺性状进行了研究，这些性状包括：穗粗、穗长、穗轴粗、穗重、株高、穗位高、散粉天数（DPS）、吐丝天数（DS）、DPS与DS之间的间隔、百粒重、容重、穗粒重和出籽率。此外，使用SPSS 11.5软件对这13个性状进行了描述性统计和相关性分析。这里提供的表型数据结果是这些农艺性状数量性状位点定位所必需的。
