杂交水稻具有明显的增产优势,从20世纪60年代开始,我国科技人员先后育成了三系杂交水稻、两系杂交水稻、超级杂交水稻等,为中国粮食安全和世界谷物生产作出了巨大贡献。水稻作为主要农作物,在世界上120多个国家和地区广泛栽培种植,全球一半以上的人口以稻米为主食,但全球水稻平均亩产仅为200公斤左右。粮食安全成为当下全球共同关注的问题。我国的杂交水稻研究始于20世纪60年代。经过十几年的科技攻关,以“杂交水稻之父”袁隆平为首的中国杂 Hybrid rice has obvious advantages in increasing yield. Since the 1960s, our country’s scientific and technological personnel have successively cultivated three-line hybrid rice, two-line hybrid rice and super hybrid rice, which have made great contributions to China’s food security and world cereal production. As the main crop, rice is cultivated widely in over 120 countries and regions. Over half of the world’s population is dominated by rice, but the average global output of rice is only about 200 kg per mu. Food security has now become a common global concern. China’s hybrid rice research began in the 1960s. After more than 10 years of scientific and technological research to “father of hybrid rice ” Yuan Longping, headed by the Chinese miscellaneous
