摘要
川优2189是用川香29A与高配合力恢复系福恢2189配组育成的杂交晚稻新品种。经4 a在福建沙县、海南三亚进行制种高产技术研究,平均产量达3 900 kg/hm2,最高产量可达5 250 kg/hm2。文章介绍了川优2189亲本的特征特性,总结了其高产制种技术。
Chuanyou 2198,a new hybrid rice combination,was developed from the cross of a male sterile Chuanxiang 29A and the restorer line Fuhui 2198,which was is suitable to be planted as late rice.According to many years rape breeding experience and the characteristics of the parents of hybird rice Chuanyou 2198,the high-yielding seed production techniques of Chuanyou 2198 were summarized.
