Meiyou 796 is a new combination of high yielding, good quality and low light sensitive hybrid rice cultivated by Guangxi Institute of Rice, a self-selected CMS line A and self-selected high-yield restorer line Gui 796. In 2009 and 2011, the average yield of regional experiment of sensitization in Guangxi Guinan rice planting area was 7.44t / hm2 and 7.50t / hm2, respectively, which increased 4.58% and 4.36% respectively compared with that of control. The average production in 2011 was 7.37t / hm2, increased by 2.36% compared with that of the control Boyou 253; passed the approval of the Guangxi Crop Variety Approval Committee (Guisan Rice 20120019) in June 2012; and the output of high-yield demonstration planting was 9.82t / hm2 in 2014; it was promoted by the Ministry of Agriculture in 2015 Rice cultivars in southern China [Nongkunke (2015) No.4].
