牧草研究牧草耐盐突变体筛选的研究进展

通过对国内外牧草组织耐盐突变体高效再生体系的建立、突变体材料的选择、变异的来源、愈伤组织耐盐突变体的筛选、耐盐性鉴定、细胞分化、耐盐愈伤组织的分化以及再生植株的耐盐性鉴定等一系列培养筛选耐盐植株的流程和方法进行综述，旨在为提高牧草耐盐性、培育耐盐牧草新品种等提供科学理论依据，同时对今后牧草耐盐突变体研究可能出现的问题以及耐盐突变体对盐碱地的改良与利用等研究方向进行阐述，并为其他抗性育种的研究提供有价值的参考。

Research progress on selection of herbage salt-tolerant mutant

In this paper,the processes and measures of selection of herbage salt-tolerant mutants obtained in vitro were analyzed.The achievements in regeneration system establishment,selection of materials and variants,origin of variation,identify of variants,salt-tolerance identification,cell differentiation and plant regeneration were summarized and some unsolved problems were discussed as well.
