摘要

根据玉米杂交制种科研实践，研究分析了玉米杂交制种过程中诸多导致花期不遇的因素，针对性的提出了叶龄预测法和可见叶、未出叶、幼雄穗分化观察法等花期预测的有效方法，对指导玉米制种生产和提高制种量具有重要意义。

Abstract

By research and practice of corn hybrid seed production, it Studied and analysed the many kinds of cause that bring asynchronous flowering period during corn hybrid seed production. It pointed out the predictable methods of corn flowering period, such as predictable methods of leaf-age, observed method of visible leaf, unsighted leaf and young male spike differentiation etc. It is important to instruct corn seed production and improve the seed yield that these methods are applied to corn hybrid seed production.
