本文对离体培养中遗传变异性的性质及其选择试验的结果做了客观的阐述.体细胞克隆变异的遗传分析和他分子研究表明,离体培养的突变谱与自然变异和诱变剂诱变的结果并不完全一致.近年来该领域主要研究焦点是对生物和非生物胁迫抗性的选择.本文结论中提出了改良选择技术的方法,阐明了离体培养在植物育种中的应用.
This article objectively expounded the nature of genetic variability in vitro and the results of its selection experiments.Genetic analysis of somatic clonal variation and his molecular studies showed that the mutation spectrum in vitro and the natural variation and mutagenic induction The result of the change is not exactly the same.In recent years, the main research focus in this field is the choice of resistance to biotic and abiotic stress.In this paper, we propose a method of improving the selection technology and clarify the application of in vitro culture in plant breeding.
