激光育种是近几年来正在研究中的一项新的育种技术,它是利用激光作用于作物种子所产生强烈的光、热、压力、电磁场等效应,引起作物遗传特性的改变,然后通过选择培育成新品种。我场在中科院上海光机所的帮助支持下,自1975年起,进行了这项试验研究工作。三年来,我们共用九种光源120个处理,先后辐照了广陆矮4号、竹莲矮、二九青、越南早籼、中秆早、青冬6号、嘉籼2号、嘉籼7号、军协等九个品种,28345粒早籼 Laser breeding is a new breeding technique under study in recent years. It is a kind of new breeding technology which is produced by the laser on the seeds of crops, which causes the changes of the genetic characteristics of crops, and then through the selection and cultivation Into a new breed. My field with the help of the Shanghai Institute of Optics and Physics, Chinese Academy of Sciences, since 1975, conducted the pilot study. In the past three years, we shared 120 light sources with nine light sources and successively irradiated Guanglu dwarf 4, Zhulian low, Jiulongqing, early indica Vietnam, middle stalk early, Qingdong 6, Jiaxian 2, Jiaxian 2 No. 7, the military and other nine varieties, 28,345 early Indica
