提高突变频率,特别是有利突变频率,对辐射育种是极其重要的,国内外都较重视这方面的研究。目前,在花生上的报导不多。本文的目的,是探讨花生几个不同生育性状对γ射线照射后的突变效应,以寻找适宜的辐照时期及各生育时期的最实用的照射剂量,为花生辐射育种提供处理依据。 Increasing the mutation frequency, especially the favorable mutation frequency, is extremely important for radiation breeding, and the researches in this field are more emphasized at home and abroad. At present, there are not many reports on peanuts. The purpose of this paper is to investigate the mutagenic effects of several different reproductive traits on the radiation of γ-rays in peanut so as to find out the most suitable irradiating time and the most practical radiation dose in each growing period.
