舟优903由舟山市农科所用红突80与红410杂交于1989年育成。1992～1993年引入萧山市参加优质早籼新品种试验,经二年的试种,具有适应性广,产量高,米质好的特点。该品种1994年通过省品审会审定,是我省推广100万亩以上的三个优质早籼品种之一。在我市有较大的推广应用价值。为了探索舟优903的生育特性及高产栽培技术,为大面积推广提供科学依据,现将舟优903的产量表现和主要栽培技术介绍如下: Zhouyou 903 by the Zhoushan City, agricultural use Red Burst 80 and red 410 hybrid bred in 1989. Introduced Xiaoshan City from 1992 to 1993 to participate in high-quality early indica new varieties of trials, after two years of trial planting, with wide adaptability, high yield, good quality rice. The species passed the provincial product auditing in 1994 and is one of three high quality early indica varieties in our province to promote more than 1 million mu. In our city have a greater application value. In order to explore the fertility characteristics of Zhou You 903 and high-yielding cultivation techniques, to provide a scientific basis for large-scale popularization, now Zhouyou 903 yield performance and main cultivation techniques are as follows:
