dc.description.abstract Molecular marker analysis and genomic in situ hybridisation (GISH) were used to examine the process of chromosome segment introgression in BC2 diploid hybrids (2n=2x=14) between Lolium perenne and Festuca pratensis. Two genotypes having what appeared to be the same, single, introgressed chromosome segment of F. pratensis in the L. perenne background were crossed with diploid L. perenne to produce a recombinant series for the introgressed region. Physical and genetic analysis of this series showed that, while recombination seemed to be possible at all points along the chromosome arm, the rate of recombination varied depending on relative position: more recombination was detected in the interstitial region as compared with the centromeric or telomeric regions. The implications of these results for the use of GISH and molecular marker analysis in the measurement of linkage drag in backcross breeding programmes is discussed. en
