杂交晚籼协优中1号在海南高产制种技术

High-yielding Seed Production Techniques for Late Indica Hybrid Rice Combination Xieyouzhong 1 in Hainan Province

协优中1号是浙江省金华市农科院与中国水稻研究所以不育系协青早A为母本,恢复系中组14为父本共同选育的杂交晚籼新品种,2010年通过浙江省农作物品种审定。表现熟期早、高产稳产、抗稻瘟病、米质优、制种容易等特点。主要介绍了协优中1号双亲的特征特性,结合海南制种实践,总结了其在海南的高产制种技术。

A new late indica hybrid rice combination, Xieyouzhong 1,derived from the cross between a sterile line Xieqingzao A and a restorer line Zhongzu 14,was developed by Jinhua Academy of Agricultural Sciences and China National Rice Research Institute. Xieyouzhong 1 was registered and released in 2010 in Zhejiang province,which showed early-mature period,high and stable yield, strong rice blast resistance,high quality and high-yielding seed production. In this paper,we introduced the characteristics of its male and female parents,and summarized its seed production techniques in Hainan province.
