Investigation and Analysis on Ear Diameter and Ear Axis Diameter in Maize RIL Population
Maize (Zea mays L.) is a very important crop in the world. In this present study, two important agronomic traits related to yield, ear diameter (ED) and ear axis diameter (EAD), were investigate in a maize recombinant inbred line (RIL) population derived from the cross of Mo17 and Huangzao4. Furthermore, the descriptive statistics, analysis of variance and correlation analysis were performed using SPSS 11.5 software in the RIL population. The results are useful for further developing quantitative trait locus mapping and molecular marker-assisted selection for ED and EAD in maize.
