摘  要:
利用化学诱变剂甲基磺酸乙酯(EMS)诱变处理国麦301小麦种子,构建小麦EMS突变体库,旨在为小麦功能基因组学研究和分子育种准备基础材料。对M2代全生育期田间及收获后进行生物学性状及农艺性状鉴定。结果表明,突变群体的表型变异率为6.398%;获得了幼苗、叶、茎、穗、熟期等的突变体769个,变异类型丰富。

摘  要:
Wheat mutants are the basic materials for functional genomics and breeding. The mutant library of Guomai 301 was built by using EMS as chemical mutagen in this study,which laid a foundation for wheat functional genomics research. During the whole growth period after sowing,many biological traits of the mutant lines in M2 generation were observed and recorded. The phenotypic mutation rate in M2was6. 398%. Total 769 mutant individuals were obtained. The mutated traits included these of seedling habits,leaf,plant height,spike,maturity,grain,etc. The mutant library of Guomai 301 induced with EMS provided new useful germplasms for wheat genetics and breeding.
