摘  要：
全优785是贵州省农业科学院水稻研究所用自育恢复系黔恢785与福建省农业科学院水稻研究所选育的三系不育系全丰A配组育成的杂交稻新组合。2011—2013年参加国家长江上游稻区区域试验,2011—2012年32个试点平均产量8.32t/hm~2,比对照Ⅱ优838增产4.86%,达极显著差异水平;2013年参加生产试验,8个试点平均产量8.64t/hm~2,比对照增产5.14%;平均生育期158.2d,与对照Ⅱ优838相当。于2014年通过农业部国家农作物品种审定委员会审定(审定编号:国审稻2014023)。适宜云南、贵州(武陵山区除外)的中低海拔籼稻区、重庆(武陵山区除外)800m以下籼稻区、四川平坝丘陵稻区、陕西南部稻区作一季中稻种植。

摘  要：
Quanyou 785,a new hybrid rice combination,was developed with the cross between restorer Qianhui 785 (bred by Guizhou Rice Research Institute)and sterile line Quanfeng A(bred by Rice Research Institute,Fujian Academy of Agricultural Sciences).It was tested in multi-location regions from 2010 to 2013 at upper reaches of the Yangtze River.The average yield was 8.32t/hm~2 and 4.86%(significantly at 0.01 level)higher than that of standard variety(CK:Ⅱyou 838)from 2011 to 2012(32 locations),and 8.64t/hm~2 in the performance experiments(8 locations)and 5.14% higher than that the CK,The growth duration on average was 158.2d and the same growth duration with CK in 2013.The National Committee of Corp Variety Release registered it as commercial cultivar in 2014(National authorized rice variety2014023).It is suitable for planting in indica rice area of Yunnan and Guizhou(except Wuling mountainous region)at middle and low altitude,indica rice area in Chongqing(except Wuling mountainous region)at altitude below 800 m,hilly rice area in Pingba,Guizhou,and south Shaanxi rice area as single-season rice variety.
