2012年度国家科学技术奖励大会于1月18日在北京隆重举行,河北省农林科学院谷子所主持完成的“抗除草剂谷子新种质的创制与利用”获得国家科技进步二等奖。该项目综合采用远缘杂交、快速回交等技术,成功地将存在于谷子近缘野生种细胞核中的抗除草剂“拿捕净”和“氟乐灵”的基因转移到栽培谷子中,特别是将存在于野生种细胞质中的抗除草剂“莠去津”基因,创造性地利用花粉作载体,转移到栽培谷子细胞质中,开辟了雄配子携带细胞质基因导入的技术途径,在世界上第一次创制出抗性基因表达完全、遗传稳
The National Science and Technology Awards 2012 was held in Beijing on January 18, and the “Achievement and Utilization of Herbicide-Resistant Millet Germplasm” completed by the Institute of Agronomy, Hebei Academy of Agriculture and Forestry won the second prize of the National Science and Technology Progress Award. The project integrates the technologies of distant hybridization and rapid backcross and successfully transfers the genes of herbicide-tolerant “net-catch” and “trifluralin” existing in the nucleus of wild relatives of millet to cultivated millet In particular, the herbicide “atrazine” gene existing in the wild cytoplasm is creatively utilized as a carrier for transferring the cytoplasm to the cultivated millet cytoplasm, opening up a technological way for introducing the male gamete cytoplasmic gene into the cytoplasm, For the first time in the world, the resistance genes were completely expressed and genetically stable
