Abstract
Genomic in situ hybridization (GISH) was used to study the nature of homologous chiasma formation in crosses between Triticum durum cv Creso, homozygous for the ph1c mutation and Thinopyrum bessarabicum The relative frequencies of wheat/wheat and wheat/Th. bessarabicum chiasma formation were determined. Pairing between apparently non-homologous Th. bessarabicum chromosomes was also observed. The potential of GISH as a tool for analyzing homologous chiasma formation in wheat/alien hybrids is discussed.
