  abstract = {{T}he relative role of sexual reproduction and mutation in shaping the diversity of clonally propagated crops is largely unknown. {W}e analyzed the genetic diversity of yam-a vegetatively-propagated crop-to gain insight into how these two factors shape its diversity in relation with farmers' classifications. {U}sing 15 microsatellite loci, we analyzed 485 samples of 10 different yam varieties. {W}e identified 33 different genotypes organized in lineages supported by high bootstrap values. {W}e computed the probability that these genotypes appeared by sexual reproduction or mutation within and between each lineage. {T}his allowed us to interpret each lineage as a product of sexual reproduction that has evolved by mutation. {M}oreover, we clearly noted a similarity between the genetic structure and farmers' classifications. {E}ach variety could thus be interpreted as being the product of sexual reproduction having evolved by mutation. {T}his highly structured diversity of farmer-managed varieties has consequences for the preservation of yam diversity.},
