| dc.description.abstractEn | A basic knowledge on linkage disequilibrium (LD) is necessary in order to determine resolution of association studies. We investigated the extent and patterns of LD in a self-incompatible species ( <em>Prunus avium</em> L.), in 3 groups (wild cherry, sweet cherry landraces and sweet cherry modern varieties), using a set of 35 microsatellite markers and the gametophytic self-incompatibility locus. Since population structure might create spurious LD, we thus used the information provided by a structure analysis published in a previous study to perform the LD analysis. In the current study, we detected a greater LD extent in sweet cherry than in wild cherry, which is plausibly due to the bottleneck associated with domestication and breeding. Higher LD values in sweet cherry sub-groups may be explained by smaller sample sizes. We also showed that the remaining structure in the groups of sweet cherry, in particular landraces, is responsible for a part of the LD extent. Intra-group relatedness may also account for extensive LD in two sub-groups. These results demonstrate, if ever necessary, the importance of controlling the genetic structure and relatedness when estimating LD. Moreover, LD decays very rapidly with genetic linkage distance in both wild and sweet cherries, which seems promising for future association studies. | |
