玉米与大刍草杂交研究进展

The Research Advances of Hybridization between Corn and Teosinte

大刍草是与玉米亲缘关系最近的野生近缘材料,利用现代技术手段将玉米与大刍草进行杂交,可以将大刍草优良的抗性基因引入玉米,扩大玉米育种种质资源基础。对大刍草基因漂流、大刍草与玉米杂交技术、杂交后代性状鉴定等方面的研究进行了论述,并对今后的研究方向和重点进行了展望。

Teosinte has improved to be a wild species closely relative to corn.Hybridization techniques between corn and teosinte allow desirable traits to be introduced into corn inbred lines,broaden the genetic bases of corn breeding.This arti-cle discusses teosinte gene flow,teosinte and corn hybrid technology,identification of hybrid characters and other aspects, including future research directions and priorities.
