摘　　要：本文着重分析了四川１９９０～１９９６年省区试的中籼迟熟参试组合及１９９０～１９９７年通过省级审定组合的产量水平、穗粒结构、生育期、抗病性、亲本的遗传背景等，对超高产育种技术进行了初步探讨。The yield level, panicle and grain structure, growth duration, resistance to diseases and the parents' genetic background of the combinations examined and approved by Sichuan during 1990～1997, and the tested combination of medium indica hybrid rice in the regional trial of Sichuan Province during 1990～1996, were mainly analysed. The breeding techniques for super high yielding rice were preliminarily studied.
