Maize (Zea mays L.) is one of the most important crops in the world. Quantitative trait locus (QTL) mapping must depend on statistical analysis on phenotypic data of traits in a segregation population. In this presented study, a recombinant inbred line (RIL) population derived from the cross Mo17 × Huangzao4 were used to investigate the trait ear number per plant (ENPP) under two nitrogen regimes. Based on the phenotypic data of the two parental inbred lines and RIL population in the trait ENPP, SPSS version 11.5 software was selected to perform descriptive statistics, analysis of variance and correlation analysis. The results could be further used for QTL identification for the agronomic trait ENPP in maize breeding program.
