目前我国优质蛋白玉米(QPM)发展面临着种质基础狭窄、自交系来源复杂、病害严重和经济价值不能体现等问题.针对这些问题提出了一些解决方案:①种质基础可通过直接利用CIMMYT现有种质,创建和利用半外来种质和将普通玉米自交系转为QPM近等基因系三种途径加以扩增.②根据种质特点、选育目标、抗穗腐病选育QPM自交系,发展多种类型的杂交种.③开发QPM的经济价值。

[Abstract]
There are some problems to develope quality protein maize (QPM) in China,which are narrow germ- plasm,not clear pedigree of QPM line,heavy disease and low econolnic value efficiency. This article gave some waysto these questions. ①The way to enhance QPM germplasm is improving CIMMYT's QPM germplasm,developing,us-ing semi-exotic germpalsm and improving normal lines to QPM lines. ② To establish the methods to select lines andcombine hybrids. ③ To exploit QPM econolnic value.
