摘要:

辐射诱变在植物新品种选育和遗传改良方面发挥着重要作用,为了能让育种者迅速准确地了解辐射诱变在木本植物上的研究和应用情况,基于CNKI数据库及国际原子能机构官网,对2000年后公开发表的木本植物辐射诱变相关文献及公布的辐射突变品种进行统计分析。从辐射诱变机理、辐射效率影响因素、突变体鉴定及分离、辐射育种成果等方面进行了全面梳理。结果表明,目前辐射诱变机理尚不清楚,影响辐射效率的关键因素为适宜辐照剂量,其次要关注辐射材料的敏感差异性,鉴定突变体的方法有表型、生理生化、细胞学及分子标记,组合使用结果更准确。总体上木本植物辐射育成品种数量不多,并且有逐渐下降的趋势。该文综述了木本植物辐射育种研究进展,对辐射诱变存在的难题诸如诱变效率低、突变方向不易控制、突变体鉴定方法不完善等给出相应解决方案,并对今后辐射育种研究方向进行了展望,旨在为植物辐射育种研究及应用提供借鉴和新思路。

Abstract:

Radiation mutagenesis plays an important role in the selection and genetic improvement of new plant varieties. In order to provide breeders with a rapid and accurate picture of the research and application of radiation mutagenesis on woody plants, based on the CNKI database and the official website of the International Atomic Energy Agency, a statistical analysis of the published literature related to radiation mutagenesis in woody plants after 2000 and the released radiation mutant species were carried out. A comprehensive review was sorted out from the aspects of radiation mutagenesis mechanism, factors affecting radiation efficiency, mutant identification and isolation, radiation breeding achievements in this field. The result shows that the mechanism of radiation mutagenesis is still unclear, the key factor affecting radiation efficiency is the appropriate irradiation dose, followed by attention to the sensitive variability of the irradiated material, and mutant identification methods are phenotypic, physiological-biochemical, cytological and molecular markers, which are used in combination for more accurate results. Overall, the number of radiation-breeding woody plant varieties is small and tends to decline gradually. The progress of radiation breeding research in woody plants is reviewed, and solutions to the problems of radiation mutagenesis, such as low mutagenesis efficiency, poor control of mutation direction and imperfect mutant identification methods, are given, and the future directions of radiation breeding research are also prospected, aiming to provide reference and new ideas for plant radiation breeding research and application.
