摘      要：Taonong 1 A, developed from the cross of Jin 23A/（644B /Yixiang B） F2 and its successive backcrosses over years, is an indica CMS line in rice. 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.
