摘　　要：采用人工授粉的方法 ,将多个近缘野生材料与栽培玉米进行杂交 ,对F1 的性状表现进行调查分析 ,根据各杂交组合F1 在株型、生长势、抗逆性、抗病性、生育期、繁茂性和育性等方面的表现特点 ,提出了远缘杂交与常规育种的青饲玉米杂交种的选育、多穗性玉米笋杂交种的选育、新型雄性不育材料的选育以及改良现有自交系和选育新型自交系等方面相结合 。By artificial pollination,distant crossing was made between cultivated maize and several wild relative materials The expression of agronomic traits was investigated based on the characteristics of hybrid progeny It was proposed that the combining distant cross with conventional breeding would be more important and necessary for future maize breeding
