摘要
小结分析了2017年我国通过省级以上审定水稻品种的基本特性。2017年我国通过省级以上审定的水稻品种共有767个次,相比2012-2016年(平均为452个)有了大幅度的提高,特别是国审品种出现井喷现象,其中,籼型常规稻49个、籼型两系杂交稻224个、籼型三系杂交稻268个、粳型常规稻169个、粳型杂交稻19个,籼粳交三系杂交稻20个、不育系18个;从品种选育主体看,2017年通过审定的品种中企业参与选育的品种占了75.10%,我国水稻商业化育种体系建设效果显著;除籼型常规稻外,其他类型品种的区试平均产量和生产试验产量均比前5年有提高,籼型常规稻、籼型两系杂交稻、籼型三系杂交稻、粳型常规稻和粳型杂交稻2017年区试平均产量分别为468.38、616.05、576.18、647.77和678.69 kg/667 m^2;2017年通过审定水稻品种的优质达标率为54.34%,总体品质比前5年有了一定程度的改善;综合抗性表现突出的品种不多,但各省份都存在一些优异的抗性种质资源。
767 rice varieties,including 49 conventional indica rice,224 two lines indica hybrid rice,268 three lines indica hybrid rice,169 conventional japonica rice,39 japonica hybrid rice,18 sterile lines,were registered by Crop Variety Approval Committee in China in 2017,the number is significantly higher than it was in 2012-2016(the average is 452).From the main body of variety breeding,75.10%varieties were bred by enterprises in 2017,China's rice commercial breeding system has achieved remarkable results.Average yield of conventional indica rice,two lines indica hybrid rice,three lines indica hybrid rice,conventional japonica rice and japonica hybrid rice were 468.38,616.05,576.18,647.77 and 678.69 kg/667 m^2 respectively,the yield of all varieties except conventional indica rice was higher than that of the previous five years.In 2017,the quality compliance rate of rice varieties was 54.34%,the quality was improved to a certain extent compared with the previous five years.There are few varieties with outstanding comprehensive resistance,but some excellent resistant germplasm resources exist in all provinces.
