本文报道了14个全附加系和25个端体附加系的C-带核型。添加的T. peregrinum染色体没有结构重排相比，相应的染色体供体登录。综合核型分析证实伞形小麦为T. longissimum的U-v基因组的供体种，长穗小麦为T. longissimum的S-v基因组的供体种。游隼。T.与祖先U和S-1基因组相比，peregrinum登录显示出较大的修饰。
C-banded karyotypes of a complete set of 14 Triticum peregrinum whole chromosome addition lines and 25 telosomic addition lines are reported. The added T. peregrinum chromosomes were not structurally rearranged compared with the corresponding chromosomes of the donor accession. Comprehensive karyotypic analysis confirmed Triticum umbellulatum as the donor species of the U-v genome and identified Triticum longissimum as the donor species of the S-v genome of T. peregrinum. Neither the U-v nor S-v genome chromosomes of the T. peregrinum accession showed large modifications when compared with the ancestral U and S-1 genomes.
