摘　　要：分析了玉米发生倒伏的因素,利用玉米矮秆突变基因的致矮特性,根据基因重组的原理,进行回交选择抗倒伏矮生系,即植株高度要适宜,株型紧凑,叶向合理,抗病性强等,并进行基因型鉴定。This paper analyzes the factors of maize lodging place,Dwarf gene in corn caused by short features,according to the principle of genetic recombination,selection for lodging dwarf backcross lines,The plant height to fit,compact plant type,leaf to the rational,and strong disease resistance and Identify the genotype.

关 键 词：玉米 抗倒伏 矮生基因
