Résumé
Despite the importance of grapevine (Vitis vinifera L.), relatively few parentages were revealed until now because small databases were analyzed. In the present work, we developed a useful and readable routine for the analysis of large data set, integrating FaMoz software. The routine was applied to a data set consisting of 2,704 individuals of the French national INRA germplasm collection of grapevine, analyzed using 20 SSRs markers well scattered over the genome. The large-scale parentage analysis enabled the identification of several kin relationships. The kingroup of ‘Chardonnay’, one of the most celebrated international grapevine cultivars, was then revealed.
