辐射处理玉米种子,是创造玉米育种基础材料的方法之一。1971年以来,我们先后用X射线、钴~(60)γ射线等物理诱变因素处理了一些玉米农家品种、自交系和单交种,诱变出几种玉米的突变类型,现将诱变结果简介如下: 1.通过辐射诱发突变,可以改变玉米籽粒类型,提高玉米籽粒的食用品质。在利用辐射手段处理玉米自交系、农家品种和一代杂交种诱发突变以选育创造新自交系的过程 Radiation treatment of corn seeds is one of the ways to create the basic material for maize breeding. Since 1971, we have treated some maize varieties, inbred lines and single cross breeds with several physical mutation factors, such as X-ray, cobalt-60 gamma ray, etc., and mutated several mutant types of maize. Variable results are summarized as follows: 1. By radiation-induced mutation, you can change the type of corn seeds and improve corn edible quality. In the use of radiation to deal with maize inbreds, peasant breeds and generation of hybrids to induce mutations in breeding to create new inbred lines
