籼型三系杂交稻繁优609的选育

为培育高产、高抗、米质优的杂交稻新组合,选用福建省农业科学院水稻研究所的优质、抗稻瘟三系不育系繁源A与强优势恢复系帮恢609配组,选育出籼型三系杂交稻繁优609,该品种经多地试种,表现出较强的杂种优势。2013年参加长江上游中籼迟熟组区域试验,表现出群体整齐、熟期转色好、丰产性突出、米质优等特点,适宜我国长江上游作一季中稻种植;2016年通过国家农作物品种审定委员会稻专业委员会审定(国审稻2016018)。本文总结了该品种的选育过程、特征特性,以及在区域试验、生产试验中的产量、抗性和米质的表现,并对杂交稻育种技术理论进行探讨。

Breeding of Three-line Indica Hybrid Rice Variety‘Fanyou 609’

In order to cultivate a new hybrid rice combination with high yield,high resistance and excellent rice quality,the three-line sterile line Fanyuan A breeded by Rice Research Institute of Fujian Academy of Agricultural Science was crossed with the strong dominant restorer line Banghui 609,and finally the three-line indica hybrid rice Fanyu 609 was created.The hybrid rice variety showed strong heterosis through multiple field tests.In 2013,this variety participated in the regional experiment of late maturity indica group in the upper reaches of the Yangtze River,showing the characteristics of neat population,good color turning at ripe stage,outstanding high yield,and high quality rice,which was suitable for growing mid-season rice in the upper reaches of the Yangtze River in China.And,in 2016,this rice variety was approved by the Rice Specialized Committee of the National Crop Variety Certification Committee(National Certification Rice 2016018).This paper summarized the breeding process and characteristics of the variety,as well as the yield,resistance and rice quality in the regional test and production test,and discussed the breeding theory of hybrid rice.
