自从六十年代激光这门新兴技术问世以来,国内外在继原子能辐射育种之后,又开展了激光诱变育种的研究工作。历史虽较短,但已取得不少可喜的成效。研究表明,激光能引起农作物染色体畸变,用它处理的水稻种子已获得矮杆、早熟、高产的新品系,开始示范推广;处理的小麦也获得杆矮、粒大、早熟的突变类型,正

Since the advent of the emerging laser technology in 1960s, the research of laser mutation breeding has been carried out at home and abroad after the radiation of atomic energy. Although history is short, a lot of good results have been achieved. Studies have shown that laser can cause chromosome aberrations in crops. Rice seeds treated with it have obtained new varieties with short stem, early maturity and high yield, and have begun to be popularized and popularized. The treated wheat also has short, large and precocious mutation types
