辐射育种是植物有效育种方法之一。我国已用此法培育出许多有经济价值的农作物新品种。近年来,国内外对这项工作逐渐引起重视,但是,在林木育种工作中还是个新课题。遵照毛主席关于“我们必须打破常规,尽量采用先进技术”的教导,我所于1973年开展了此项试验研究。 Radiation breeding is one of the effective breeding methods for plants. This method has been used by our country to breed many new crop varieties with economic value. In recent years, more and more attention has been paid to this work at home and abroad, however, it is still a new topic in the work of tree breeding. In accordance with Chairman Mao’s teaching on “We must break the routine and try our best to adopt advanced technologies,” I conducted this pilot study in 1973.
