摘要
分析了2016年我国水稻品种的审定情况及通过省级以上审定水稻品种的基本特性。结果表明,2016年我国通过省级以上审定的水稻品种共有492个次(有13个品种通过两个及以上省份审定),其中,籼型常规稻36个、籼型两系杂交稻137个、籼型三系杂交稻166个、粳型常规稻87个、粳型杂交稻25个(其中19个为籼粳杂交稻)、不育系41个。区试平均产量籼型常规稻为501.36 kg/667 m^2,比区试对照增产3.86%;籼型两系杂交稻为592.54 kg/667 m^2,比区试对照增产5.46%;籼型三系杂交稻为552.96 kg/667 m^2,比区试对照增产5.16%;粳型常规稻为624.94 kg/667 m^2,比区试对照增产7.48%;粳型杂交稻为651.96 kg/667 m^2,比区试对照增产8.91%。品种品质表现是粳稻好于籼稻,常规稻好于杂交稻,优质达标率粳稻为51.79%、籼稻为43.95%,常规稻为56.91%、杂交水稻为41.77%。并列举了一些对单个病害抗性表现较好的品种。
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 m^2,increased by 3.86% compared with the control; two lines indica hybrid rice was 592.54 kg/667 m^2,increased by 5.46% compared with the control; three lines indica hybrid rice was 552.96 kg/667 m^2,increased by 5.16% compared with the control; conventional japonica rice was 624.94 kg/667 m^2,increased by 7.48% compared with the control; japonica hybrid rice was 651.96 kg/667 m^2,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.
