| Abstract: | Using the genomic in situ hybridization (GISH) technique, one translocation line, seven translocation-addition lines, five
translocation plus translocation addition lines and two ditelosomic addition lines were identified in backcross progenies
of Triticum aestivum L. -Psathyrostachys juncea (Fisch.) Nevski intergeneric hybrids. No complete P. juncea chromosomes were
detected in the 25 lines studied. The results suggest that intact P. juncea chromosomes may be difficult to isolate in a wheat
background.
