射线能引起生物的遗传变异。人们为利用射线这一功能,早在1935年就写有关于用X射线诱发柑桔突变的试验报告。但在六十年代前辐射育种研究进展比较缓慢,六十年代后,世界上许多国家开展了这项研究工作,近年来发表了用种种不同射线诱发突变的许多文章,取得不少成绩。如国外应用辐射处理育成了果实色择鲜艳,较抗白粉病 Ray can cause biological genetic variation. People use the ray of this function, as early as 1935 written on the X-ray induced citrus mutation test report. However, research on radiation breeding before the 1960s was relatively slow. Since the 1960s, many countries in the world have carried out this research. In recent years, many articles on using different radiation-induced mutations have been published and many achievements have been made. Such as foreign application of radiation treatment bred fruit color choice bright, more resistant to powdery mildew
