利用荧光原位杂交技术对Amigo小麦进行染色体涂染，结果表明，除黑麦的T1 AL·1 RS易位外，还存在长穗冰草3Ae#1染色体上的一个片段（2n= 10 x =70）。该染色体位于1B染色体的随体上，易位染色体命名为T1 BL·1BS-3Ae#1L。T1 BL·1BS-3Ae#1L是从Teewon小麦中遗传而来的，携带抗茎锈病基因（Sr 24）和抗叶锈病基因（Lr 24）。Agent、TAP 48、TAP 67、Teewon和Amigo等4个Sr 24/Lr 24载体小麦系的Agropyron染色体片段均显示出一条诊断性的C-带，它们均来自同一染色体3Ae#1。
Chromosome painting using multicolor fluorescencein situhybridization showed that, in addition to the T1AL·1RS translocation derived from rye, a segment from chromosome 3Ae#1 ofAgropyron elongatum(2n=10x =70), is present in Amigo wheat. TheAgropyronchromosome segment is located on the satellite of chromosome 1B and the translocation chromosome is designated as T1BL·1BS-3Ae#1L. T1BL·1BS-3Ae#1L was inherited from Teewon wheat and carries resistance genes to stem rust (Sr24) and leaf rust (Lr24). TheAgropyronchromosome segments in differentSr24/Lr24carrier wheat lines, including Agent, TAP 48, TAP 67, Teewon, and Amigo, showed a diagnostic C-band, and were derived from the same chromosome, 3Ae#1.
