三系法杂交粳稻品种金粳优132的选育

Breeding of Three-line Japonical Hybrid Combination Jinjingyou 132

为中早粳晚熟稻区改良杂交粳稻稻米品质,提高粳稻单位面积产量,采用杂种优势利用方法,在育成优良BT型三系不育系金粳13A和恢复系津恢2号的基础上,组配高产、优质、多抗杂交粳稻品种金粳优132,经国家北方稻区中早粳晚熟组2008—2009年区域试验,金粳优132号平均单产9.81 t·hm-2,比对照金珠1号增产12.94%;2012年生产试验平均单产9.97t·hm-2,比对照增产13.7%。2010年通过国家农作物品种审定委员会审定,准予在辽宁省南部、北京市、天津市稻区种植。金粳优132是我国北方稻区首个米质达国标优质稻谷1级标准的国审杂交粳稻品种。

To improve the quality and increase the yield of the hybrid japonica rice in middle-early japonica rice region, a three-line hybrid japonica combination Jinjingyou 132 with high yield, good quality and multiple resistance was developed from the cross between BT-type CMS line Jinjingl3A and restoration line Jinhui 2. The average yield of Jinjingyou132 was 9.81 t-hm-2,10.5 percent higher than that of control in national muhiple-location regional experiment during 2008--2009, and the average yield was 9.97 t. hm-2, 13.7 percent higher than that of control in national rice productive experiment in 2009. Jinjingyou132 was registered by National Crop Variety Approval Committee in 2010 so that it can be planted in south Liaoning, Tianjin and Beijing. Jinjingyou 132 was the first national registered rice variety which attained the first class level of the national rice quality standard in north rice region.
