辐射育种在我省已被广泛应用于粮食作物、经济作物、果树、林木、蚕桑、蔬菜、药材及微生物等方面。通过多年的实践,已获得了一些优良突变体,育成了一些优良的品种或品系,为农业生产的发展作出了贡献,对促进本学科的进一步发展,积累了资料和经验。回顾我省辐射育种发展的历程和所取得的成就大致可分为三个阶段: 第一阶段是由研究辐射的小剂量刺激作用而逐渐转为研究辐射诱变。如甘肃农大在对饲用胡萝卜的研究中,西北畜牧兽医研究所在对紫粒苏丹草的研究中,均发现适宜辐照量(小剂量)处理,不仅可增加产量而且可提高品质。而在大辐照量下,则产生辐射抑制、损伤和诱变作用。兰州大学在对春小麦、棉花、蚕豆的研究中,发现低辐照量下,可促进根尖细胞的
Radiation breeding in our province has been widely used in food crops, cash crops, fruit trees, trees, sericulture, vegetables, herbs and microorganisms and so on. Through years of practice, some excellent mutants have been obtained, some fine varieties or strains have been bred, and contributions have been made to the development of agricultural production. Data and experience have been accumulated to promote the further development of this discipline. Recalling the development of radiation breeding in our province and the progress made can be broadly divided into three stages: The first stage is the study of small doses of radiation stimuli and gradually transferred to the study of radiation mutagenesis. In Gansu Nongda research on feeding carrots, Northwest Institute of Animal Husbandry and Veterinary Research on purple Sudan grass, we found that the appropriate radiation (small dose) treatment, not only increase the yield but also improve the quality. In the large amount of radiation, the resulting radiation inhibition, damage and mutagenesis. Lanzhou University in spring wheat, cotton, broad bean research, found that low doses of radiation, can promote root tip cells
