摘　　要：冀单18号是由“黄早_4×CB_5”组配的玉米单交种,丰产,适应性广,抗病性强,对肥水反应敏感,对光温气反应迟钝,稳产.在冀中南种植,生育期93天左右,麦田套种与夏播皆可.本项研究以亲本种质基础分析和生态型演变进化的有关理论作指导,探讨了现玉米生态阶段关键生态性状因素的选择指标.The new single-hybrid variety of maize 'Ji Dan 18' is derived from Huangzao 4 ×CB5. It is characterized by stable aud high yield, fine adaptation,strong resistance to diseases and middle early stage of mature. This variety is sensitive to fertilizer and water, but nonsensitive to light,temperature and air. It is fit for interplanting with wheat and summer sowing. Planting area of the hybrid amounted to one million mu in 1988. The study was carried out with the help of parent germ plasm basis analysis method and under the direction of ecotype evolution theory. In this paper the authors have probed into the selecting targets of main ecological character in current maize ecological phase.
