Abstract
Using genomicin-situ hybridization (GISH) technique, 7 translocation-addition lines, 6 translocation and translocation-addition lines, 2 ditelosomic addition lines and 1 translocation line were identified fromTriticum aestivum L. -Psathyrostachys juncea (Fisch.) Nevski intergeneric hybrids, of which translocation-addition and translocation and translocation-addition lines were not found in other reports. No substitutions and disornic additions were detected in the, hybrids and breakages occurred in allP. juncea chromosomes studied. Results have shown that the improved GISH technique is a rapid and economical method for use in this field.
