It is characteristic of good agronomic characters, restorability, fine grain quality and high multiplication and hybrid seed yield. In 2012, its F1 hybrid combination Taoyou Xi- angzhan （Taonong 1A/Huanghuazhan） was evaluated as a 2nd class fine quality rice variety in Hunan Province. Both Taonong 1A and Taoyou Xiangzhan were regis- tered for release to commercial production by Hunan Provincial Crop Variety Ap- praisal Committee in 2015.展开更多
