Abstract
Genomic in situ hybridization was used to study the relative frequency of wheat/wheat and wheat/rye homoeologous chiasma formation in Triticum aestivum cv. Chinese Spring tetrasomic for chromosome 3B × Secale cereale cv. Petkus Spring hybrids. In addition to wheat/wheat and wheat/rye homoeologous chiasma formation, pairing between apparently non-homologous rye chromosomes was also observed. The implications of the results obtained for the introgression of rye chromatin into wheat is discussed.
