摘要
阐述了超高产杂交粳稻育种的历史、生产应用现状和存在的问题,认为发掘与利用优异基因资源、进行杂种优势利用的技术创新是杂交粳稻取得突破的前提,提出了南方水稻主产区超高产杂交粳稻育种途径和株型模式,并育成产量潜力12t/hm2的超高产杂交粳稻组合。建议加强超高产杂交粳稻配套栽培技术研究和技术培训。
It was expatiated on the super high yield breeding history of japonica hybrid rice, the status quo and the problem of japonica hybrid rice production. It will be excavated gene with fine and differing, and it will be innovated the way and technology of the heterosis utilization. The breeding way and plant type were discussed on japonica hybrid rice in south main rice growing district. The japonica hybrid rice combinations were bred with 12t/hm2 of highest yield. The countermeasure of developing japonica hybrid rice were suggested.
