摘　　要：特优582是广西农业科学院水稻研究所利用龙特浦A与自选育的广亲和强恢复系桂恢582配组育成的中熟早籼超级稻新品种。2007年、2008年广西杂交水稻区域试验和生产试验中平均产量分别为7 653.45kg/hm2和8 276.70kg/hm2,分别比对照特优63增产6.08%和9.23%,2009年5月通过广西品种审定委员会审定(桂审稻2009010);2010年7月高产示范种植产量为10 819.50kg/hm2,达国家双季稻区超级稻品种产量指标要求,2011年1月被国家农业部认定为超级稻品种[农办科(2011)10号];2012-2013年连续2年成为国家农业部和广西区农业厅推介的华南稻区主导品种。Teyou 582,derived from Longtepu A and Guihui 582,a strong restoring line with wide compatibility,is a middle-maturity early indica super rice cultivar developed by Rice Research Institute, Guangxi Academy of Agricultural Sciences.The average yields of Teyou 582 were 7 653.45 kg/hm2 and 8 276.70 kg/hm2 in Guangxi regional trial during 2007-2008,which increased by 6.08% and 9.23% as compared to the control Teyou 63. In May of 2009, it was registered and released to commercial production by the Guangxi Crop Variety Appraisal Committees（Guishendao 2009010）.The conversion dry cereal yield of Teyou 582 was 10 819.50 kg/hm2 under high-yield demonstration fields in July of 2010, which reached the yield index of super rice for double cropping rice area of Southern China,and it was identified as super rice variety in January of 2011 [Nongbanke （2011 ）10 ].In 2012 and 2013,it was identified as dominant variety in Southern China by Ministry of Agriculture and Guangxi agricultural department.
