Tritordeum has brittle rachis. In contrast, the 2D(2Hch) and 3Hv(3Hch) substitution lines showed non-brittle rachis, and they also have tenacious glumes and compact spikes which are excellent characters to improve the tritordeum threshing. We have also developed different combinations between 2D and 3Hv translocation lines in tritordeum. We present in this paper the identification and characterisation of all these introgression lines in tritordeum by fluorescent in situ hybridisation.
