Abstract: Three maize hybrids that utilized widely on maize production in China were chosen as the materials for the study on correlation between stem characters and lodging resistance. The result indicated that: the planting density,stem pull,stem puncture strength,stem diameter,plant height and ear height were significant relationship with lodging resistance at 0. 01 level; the support root numbers was significant relationship with lodging resistance at 0. 05 level. Planting density,stem puncture strength,stem diameter and ear height were the principal direct factors for variety lodging resistance. They could act the target for variety lodging resistance.

Key words: Maize(Zea mays, L. ), Pull, Puncture, Lodging resistance, Correlation analysis, Path analysis
