Résumé
Despite the importance of grapevine (Vitis vinifera), relatively few parentages were revealed until now because small databases were analysed. We developed a useful and readable routine for the analysis of large data set, integrating the FaMoz software. The routine was applied to a data set consisting of 2704 individuals of the French national INRA germplasm collection analysed using 20 SSR 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, is discussed.
