Abstract
Summary: Colinearity between wheat and rice genomes is quite well established at the chromosome level, but less is known at a finer level. We tried to specify these relationships for the wheat 5BS chromosome-arm distal region, where a major locus for crossability was located. By developing AFLP markers, we succeeded to locate this major QTL more precisely. One cloned AFLP fragment mapped to rice chromosome 11, which was in agreement with a rice chromosome-11 linkage block reported in this region. However a second marker, a RFLP probe, showed a break in synteny because it mapped to rice long-arm chromosomes 1 and 5, while screening a rice BAC library with the same probe identified rice chromosomes 5 and 6. Therefore, we concluded that the syntenic relationships were more complex at the fine level. The observed results might indicate the presence of a linkage block carrying a crossability gene on wheat groups 1, 5 and 7, and also on rice chromosomes 5 and 6
