摘要
以1999-2002年在云南省水富县采用不同海拔分期播种的方法对云光15号双亲特征特性及母本蜀光357S育性转换规律的研究结果为基础,提出秋繁制种并对其高产制种技术进行研究。2001-2003年共制种13.3hm2,其单产稳定在2.98 L/hm2以上,高产农户单产达4.28 L/hm2。
The study on the main characters of the parents and the regulations of fertility changes for Shuguang357S, the female parent of Yunguang15, was conducted in at different altitudes Shuifu county, Yunnan province, from 1999 to 2002. A new strategy of hybrid rice seed production, autumn producing system was put forward, and the high seed production techniques were also discussed. By using this system, we have produced hybrid seed for 13.3 hm2 from 2001to 2002, and its average yield was stabilized above 2.98 t/ hm2,the highest case in fanner field was reached 4.28 t/ hm2.
