| Abstract: | It has been suggested that map information for molecular markers can be used to strengthen finterprinting analyses. The success
of this strategy depends on the distribution of linkage disequilibrium over the genome. Using 451 mapped AFLP markers, we
investigated the occurrence of linkage disequilibrium in nine sugar beet breeding lines. A low but significant level of linkage
disequilibrium was found for unlinked markers. Only for very tigthly linked (<3 cM) markers was this level substantially higher.
This implies that little is gained in utilising the map position of the markers in fingerprinting applications.
