Abstract:492 rice varieties, including 36 conventional indica rice, 137 two lines indica hybrid rice, 166 three lines indica hybrid rice, 87 conventional japonica rice, 25 japonica hybrid rice, 41 sterile lines, were registered by Crop Variety Approval Committee in China in 2016. Average yield of conventional indica rice was 501.36 kg/667 m2, increased by 3.86% compared with the control;two lines in-dica hybrid rice was 592.54 kg/667 m2, increased by 5.46% compared with the control; three lines indica hybrid rice was 552.96 kg/667 m2, increased by 5.16% compared with the control; conventional japonica rice was 624.94 kg/667 m2, increased by 7.48% com-pared with the control; japonica hybrid rice was 651.96 kg/667 m2, increased by 8.91% compared with the control. The quality of japonica rice was significantly better than indica rice; the quality of conventional rice was significantly better than hybrid rice. The quality compliance rate of japonica rice was 51.79%, indica rice was 43.95%, conventional rice was 56.91%, hybrid rice was 41.77%. Some varieties with good resistance to single disease were listed.
Keywords:rice  registered varieties  yield  grain quality  resistance to diseases and insect pests  China
