利用电离辐射或化学诱变剂等理化诱变因素处理农作物种子、苗木或其它器官,能引起植物的基因突变或染色体突变,再通过有效的选择和培育,从而获得各种突变新品种或突变体,为农业生产服务,并丰富植物种质资源。近十多年来,世界各国农作物突变育种发展迅速,成果显著。本文拟就国内外诱变育种的主要进展与发展动向,简要加以概述。农作物诱变育种的主要进展一、育成的新品种数目多,经济效益显著据国际原子能机构(IAEA)1985年统计,世界各国利用诱变育成的各种农作物新
The use of ionizing radiation or chemical mutagens and other physical and chemical mutagenesis factors dealing with crop seeds, seedlings or other organs, can cause plant mutations or chromosome mutations, and then through the effective selection and cultivation, access to a variety of new varieties or mutations , Serving agricultural production and enriching plant germplasm resources. In the recent ten years, the mutation breeding of crops in various countries in the world has witnessed rapid development with remarkable achievements. In this paper, the main progress and development trend of mutagenic breeding at home and abroad are briefly summarized. MAJOR PROGRESS IN MAKING MUCHING MUTATIONS OF CROPS A. The number of new bred varieties is significant and the economic benefits are significant. According to the 1985 statistics of the International Atomic Energy Agency (IAEA), all kinds of crops newly raised by mutagenesis in various countries in the world
