水稻源于亚洲,现已在全球一百多个国家和地区种植,稻米成为全球一半以上人口的主食。为了解决人类的吃饭问题,以袁隆平为首的中国科学家从1964年起开展水稻杂种优势利用研究,历经十年的艰苦努力,终于通过“三系法”于1973年育成了世界上第一个杂交水稻组合。近年来,科研人员又在超级杂交水稻研究领域取得了重大技术突破,已育成一批超级杂交水稻组合,大面积产量潜力达12～15吨/公顷(1公顷=10000平方米)。目前,中国已经建立了以分子技术与常规育种手段相结合
Rice originates in Asia and is now grown in more than 100 countries and regions. Rice is the staple food of more than half of the world’s population. In order to solve the problem of human eating, Chinese scientists led by Yuan Longping carried out researches on the utilization of rice heterosis since 1964. After ten years of hard work, they finally became the first one in the world through the “Three-line Law” in 1973 Hybrid rice combinations. In recent years, researchers have made significant technological breakthroughs in the field of super hybrid rice research. A group of super hybrid rice combinations have been bred. The potential for large-scale production is 12-15 tons / hectare (1 hectare = 10,000 m²). At present, China has established a combination of molecular techniques and conventional breeding methods
