Abstract: 【Objective】 To investigate the variation and heterosis of lodging resistance traits in maize hybrids with different plant heights. 【Methods】 In this study, nine maize hybrids of different plant heights and their parents were used as materials, the plant morphology, third internode morphology, rind puncture strength, and the lodging rate was determined. 【Results】 The results showed that with the increase of hybrid maize plant height, the ear height and ear coefficient of maize hybrids increased. The basal internode length became longer and the stalk thickness coefficient became lower. Stalk rind puncture strength became weaker and field lodging rate increased. Correlation analysis showed that stalk rind puncture strength of maize hybrids was significantly and negatively correlated with plant height, ear height and basal internode length. Heterosis analysis showed that maize hybrids had a high heterosis advantage in plant height, high heterosis advantage in long-stalked variety was higher than that in short-stalked variety. The super-mother advantage, mid-parent advantage and hybrid advantage index of ear height all showed an increase with plant height. Both mid-parental and heterosis for basal internode length of maize were higher, and super-mother advantage was higher than super-father advantage, and long-stalked variety were higher than short-stalked variety. 【Conclusion】 The heterosis index of stalk rind puncture strength is stronger, and super-father advantage is greater than super-mother advantage. Therefore, the selection of maize hybrids should focus on the selection of the plant type of the parental inbred lines, and thus can provide a reliable basis for speeding up the selection of high-yield and lodging-resistant varieties.
