  abstract = {{B}ackground: {C}lonal propagation is a particular reproductive system found in both the plant and animal kingdoms, from human parasites to clonally propagated crops. {C}lonal diversity provides information about plant and animal evolutionary history, i.e. how clones spread, or the age of a particular clone. {I}n plants, this could provide valuable information about agrobiodiversity dynamics and more broadly about the evolutionary history of a particular crop. {W}e studied the evolutionary history of yam, {D}ioscorea rotundata. {I}n {A}frica, {Y}am is cultivated by tuber clonal propagation. {R}esults: {W}e used 12 microsatellite markers to identify intra-clonal diversity in yam varieties. {W}e then used this diversity to assess the relative ages of clones. {U}sing simulations, we assessed how {A}pproximate {B}ayesian {C}omputation could use clonal diversity to estimate the age of a clone depending on the size of the sample, the number of independent samples and the number of markers. {W}e then applied this approach to our particular dataset and showed that the relative ages of varieties could be estimated, and that each variety could be ranked by age. {C}onclusions: {W}e give a first estimation of clone age in an approximate {B}ayesian framework. {H}owever the precise estimation of clone age depends on the precision of the mutation rate. {W}e provide useful information on agrobiodiversity dynamics and suggest recurrent creation of varietal diversity in a clonally propagated crop.},
