The kindgroup of the cultivar 'Chardonnay' revealed
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.
