作物辐射育种是农业上利用原子能的一个重要方面,是继系统选育和杂交育种之后发展起来的一项育种新技术。它是利用放射性射线,如Χ射线,γ射线,β射线,中子和无线电微波等处理作物,从而引起作物遗传性的改变,产生各种各样变异,经过人工选择、培育、产生优良品种的方法。它的优点是:可提高变异频率,有利于改变单一特性,缩短育种年限。辐射处理方法,有外照射和内照射两种。外照射是利用各
Crop radiation breeding is an important aspect of agricultural use of atomic energy. It is a new breeding technology developed after system selection and crossbreeding. It is the use of radioactive rays, such as the X-ray, gamma rays, beta rays, neutrons and radio microwaves and other crops, resulting in crop genetic changes, resulting in a variety of variations, after artificial selection, nurturing, producing good varieties method. Its advantages are: can improve the frequency of mutation, is conducive to changing a single feature, shorten the breeding life. Radiation treatment methods, there are two kinds of external and internal radiation. External radiation is utilized
