中国农业科学院中国水稻研究所超级稻种质创新团队与中国科学院遗传与发育生物研究所等单位最新合作研究发现,水稻染色体拷贝数变异可调控水稻的粒长和品质,为水稻粒形的分子设计和高产优质水稻新品种培育奠定了基础。7月6日,国际著名学术期刊《自然-遗传学(Nature Genetics)》在线发表了这一研究成果。水稻粒形是衡量稻米外观品质的主要指标,同时也是影响水稻产量性状的重要因素之一,因此成为重要的水稻育种农艺性状。我国的水稻分籼、粳两个亚
Chinese Academy of Agricultural Sciences China Rice Research Institute super rice germplasm innovation and the Chinese Academy of Sciences Institute of Genetics and Development and other units of the latest collaboration found that rice chromosome copy number variation can regulate the grain length and quality of rice grain shape molecular design And the cultivation of new varieties of high yield and quality rice laid the foundation. July 6, the internationally renowned academic journal "Nature - Genetics (Nature - Genetics) published online research results. Rice grain shape is the main index to evaluate the appearance quality of rice and is also one of the important factors that affect the yield traits of rice. Therefore, it has become an important agronomic trait of rice breeding. China’s rice points Indica, Japonica two Asian
