摘要： 研究了宜香1577亲本的特征特性，并据此开展了宜香1577的制种技术研究和纯度控制技术研究，内容包括如何合理安排好父母本的播差期，并据父母本对“九二O”的敏感程度不同而确立各自用量及使用时期，从而为香1577的高产制种和纯度控制提出了一套有效的技术措施。

Abstract: We have carried out the study of hybrid seed production of Yixiang1577 and its parents’ characteristics. By the study of hybrid-seed-production and pureness-control techniques for hybrid rice Yixiang1577, we have made conclusions about how to arrange distance days between the dropping seeds of female parent and male parent, the usage of “920” for parents and the using time. As a result, we have had a suit of technique and measures for hybrid-seed-production and pureness -control techniques for hybrid rice Yixiang1577.
