水稻辐射育种的过程,往往会有半不孕植株的伴随出现。通过几年来的育种实践,对半不孕植株的出现及其育种效果,作了一些观察和分析,下面谈一些认识和体会。一、半不孕植株出现是辐射育种的重要特征水稻干种子经3万伦琴钴60γ射线照 Rice radiation breeding process, there will often be accompanied by emergence of semi-sterile plants. Through several years of breeding practice, the emergence of semi-sterile plants and breeding effect made some observations and analysis, the following talk about some understanding and experience. First, the emergence of semi-infertile plants is an important feature of radiation breeding Dry seeds of rice by 3 million Roentgen Cobalt 60γ-ray photos
