杂交水稻新品种协优385高产制种技术

High-yielding Seed Production Techniques of the New Hybrid Rice Cultivar Xieyou 385

协优385是贵州省水稻研究所用三系不育系协青早A与自育恢复系黔恢1385配组而成的迟熟籼型杂交稻品种,于2011年通过贵州省农作物品种审定委员会审定,具有高产、稳产、适应性广、抗逆性强、米粒有香味等特点。为加快协优385在生产上的推广应用,促进水稻生产中的新旧品种更替,确保水稻生产的可持续发展。介绍了协优385的父母本特征特性,并根据制种实践,总结了高产制种技术。

Xieyou 385, a indica hybird rice with late maturity in Guizhou Rice Research Institute, was crossed with self-fertile restoring line Qianhui 1385 （restorer line） and CMS line Qieqingzao A, and was approved by Guizhou Crop Variety Approval Committee in 2011. It is characterized by high yield, stable yield, extensive adaptability, strong stress resistance, fragrant rice kernel. For the sake of speeding up the generalization and application of Xieyou 385 in the production, promoting the replacement of new and old rice cultivars, so as to ensure the sustainable development of rice production, the characteristics of parents of Xieyou 385 were introduced. Moreover, the high-yielding seed production techniques were summarized according to the seed producing practice.
