美优796是广西农业科学院水稻研究所以自选育的不育系美A与自选育的强优势恢复系桂796配组育成的高产优质弱感光杂交水稻新组合。2009年、2011年广西桂南稻作区感光组区域试验平均产量为7.44t/hm2和7.50t/hm2,分别比对照博优253增产4.58%和4.36%;2011年生产试验平均产量为7.37t/hm2,比对照博优253增产2.36%;2012年6月通过广西农作物品种审定委员会审定(桂审稻20120019号);2014年高产示范种植产量为9.82t/hm2;2015年成为农业部推介的华南稻区水稻主导品种[农办科(2015)4号]。

Meiyou 796,derived from Mei A and Gui 796,is a fine quality,high-yielding and weakly photosensitive indica hybrid rice developed by Rice Research Institute,Guangxi Academy of Agricultural Sciences.The average yields of Meiyou 796 were 7.44 t/hm^2 and 7.50 t/hm^2 in Guangxi regional trial in 2009 and 2011,which increase by 4.58% and 4.36% as compared to the control Boyou 253.The average yield in the productive experiment was 7.37 t/hm^2 ,which increased by 2.36% as compared to the control Boyou 253.The average yield in the productive experiment was 7.37 t/hm^2 ,which increased by 2.36% as compared to the control Boyou 253.It was registered and released to commercial production by the Guangxi Crop Variety Appraisal Committees in June of 2012. The yield of Highe-yielding cultural technology was 9.82 t/hm^2 in 2014.The yield of high-yielding cultural teachnoloy was 9.82 t/hm^2 in 2014. In 2015,it was indentified as dominant variety in Southern China by Ministry of Agriculture[Nongbanke （2015）4].
