优良玉米自交系选育新方法

New Method of Elite Inbred Line Breeding in Corn

针对超级玉米超高产、优质、多抗、广适、易制种的育种目标和以耐密植为核心的多抗广适稳产性育种路线,提出优良玉米自交系选育新方法:新种质、大群体、高密度、强胁迫、变换地、严选择。同时提出理想株型是紧凑型玉米进一步发展的基础。

Aiming at the breeding objectives of the super-corn characterized by super high yield, good quality, wide adaptation, multiple resistance and easy production, and under the core breeding route of suitable to high density throu gh an ideal plant type and the multiple resistances, wide adaptation, the excell ent lines breeding methods were put forward, namely new germplasm, big selection population, high density, strong stress, changing growing environment and stric t selection, At the same time the notion of the ideal plant type was the advance of compact plant type corn.
