东北是我国最重要的优质口粮生产基地。黑龙江省的水稻种植区域大致分为五个积温带,其中以第三积温带面积最大(约3500万亩),选育适合第三积温带的优质抗稻瘟品种是东北稻区育种的最重要目标之一。中国科学院遗传与发育生物学研究所姚善国研究组主要致力于东北粳稻的多基因组装设计育种研究。以历史栽培面积最大品种空育131为底盘,通
Northeast China is the most important high-quality rations production base. The rice planting area in Heilongjiang Province can be roughly divided into five accumulated temperate zones, of which the most important area is the third accumulated temperate zone (about 35 million mu), and the breeding of high quality anti-rice blast varieties suitable for the third accumulated temperate zone is the most important One of the goals. Yao Shanguo, Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, is mainly engaged in the research of polygenetic assembly and breeding in Northeast japonica rice. With the history of the largest cultivated area Yuyu 131 as the chassis, pass
