为进一步提高中早粳晚熟稻区粳稻产量,采用杂交育种方法,育成优良BT型三系不育系金粳11A和恢复系津恢1号;在此基础上组配选育出高产、优质、多抗杂交粳稻新品种金粳优11A/津恢1号。经国家北方稻区中早粳晚熟组2010—2012年区域试验,金粳优11号平均单产9.71t/hm2,比对照津原85增产11.57%;2012年生产试验平均单产9.97t/hm2,比对照增产11.93%。2013年通过国家农作物品种审定委员会审定,适宜在辽宁省南部、北京市和天津市稻区种植。
In order to further improve the yield of late-maturing japonica rice in middle-early japonica rice, the elite BT type CMS line Jinjing 11A and the restorer line Jinhui No.1 were bred by cross breeding method. On the basis of this, Multi - resistant japonica hybrid rice Jinjing You 11A / Jin Hui 1. According to the regional experiment of late japonica late maturing group in the northern part of China in 2010-2012, the average yield of Jinjingyou 11 was 9.71t / hm2, which was 11.57% higher than that of the control Jinyuan 85. The average yield of production was 9.97t / hm2 in 2012, Yield 11.93%. In 2013 through the National Crop Variety Approval Committee validated, suitable for planting in southern Liaoning Province, Beijing and Tianjin rice.
