摘要：

Meiosis of triticalextetraploid rye hybrids (genome constitution ABRRR) was analysed by genomic in situ hybridization (GISH) and C-banding. The results obtained reveal a considerable difference between these techniques with regard to their efficiency in detecting any type of pairing, either homologous or homoeologous. Thus the percentage of pollen mother cells containing wheat/rye homoeologous associations determined by C-banding and GISH was 2.5 and 9.2, respectively. Such a discrepancy can be ascribed to a certain proportion of wheat/rye associations not being identified by C-banding. The potential and limitations of the two techniques for meiotic analysis are discussed.
