Crossovers (CO) are necessary in breeding to introgress regions of interest in agronomic varieties from cultivated species such as bread wheat (Triticum aestivum L.). In order to evaluate the impact of factors influencing CO formation, we started the characterisation of their distribution on the largest wheat chromosome (chromosome 3B, 995 Mb) using the recently developed physical map as well as some sequenced regions of few megabases. Comparison between a dense genetic map (102 markers) and a physical deletion map shows that 77 % of CO are present in the distal regions covering 25 % of the chromosome. Comparison between different genetic maps indicates that this distribution is conserved despite local differences of CO ratio between differ...
