我国水稻矮化,国际水稻所育成IR8引起的“绿色革命”,以及我国杂交水稻奇绩的出现,使全球的水稻生产登峰造极。然而,大米的消耗量随人口膨胀而剧增,需求量预计将愈来愈大。在工业化与商业化的社会进化中,可耕地面积在大多数国家每年以3—5％的高速减少。科学从来没有峰与极,今天,全球多领域的科学家在多途径探索水稻产量的另一次突破。呼声最高的要推远缘杂交与生物技术。远缘杂交指亲缘关系较远,遗传距离较大的分类单位间之杂交。水稻亚种以上的交
The dwarfing of rice in China, the “green revolution” caused by IR8 bred by the International Rice Institute, and the advent of the miracle of hybrid rice in China have made global rice production extremely successful. However, the consumption of rice increases rapidly as the population expands and the demand is expected to grow larger and larger. In industrialized and commercialized societies, the area of arable land decreases by 3-5% annually in most countries. There has never been a peak in science. Today, scientists in many fields around the world are exploring ways to make another breakthrough in rice production. Voice utmost to push the distant hybridization and biotechnology. Distant hybridization refers to the distant kinship, genetic distance larger taxon between the hybrids. Rice subspecies more than pay
