Title	Chromosome painting of Amigo wheat.
Journal	Theoretical and Applied Genetics
Year	1994

Language	English
Abstract	Chromosome painting using multicolor fluorescence in situ hybridization showed that, in addition to the T1AL.1RS translocation derived from rye, a segment from chromosome 3Ae#1 of Agropyron elongatum (2n=10x=70), is present in Amigo wheat. The Agropyron chromosome 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). The Agropyron chromosome segments in different Sr24/Lr24 carrier 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
Gene	Sr24 (Triticum)
