| Abstract: | The chromosomal composition of the spring triticale line 131/7 carrying a rye—wheat translocation was studied using GISH,
C-banding, and SSR analysis. The complex analysis revealed the presence of a pair of 2D chromosomes and T2RS.2RL-2BL translocation
in the genome of the hexaploid triticale line 131/7. The break point in the translocated chromosome is between the markers
Xwmc592 and Xwmc441, loci 63.9 cM and 76.8 cM on the linkage map (Wheat, Consensus SSR, 2004 NA-SSR-2004-2B) and in the region
C-2BL2-0.36 on the physical map (Wheat, Physic al, SSR). The analysis of the line enables its use in breeding programs and
in genetic studies. |
