Famoz: a software for large scale parentage analysis in Vitis vinifera L. species

International audienceParentage analysis in grape (Vitis vinifera L.) is becoming more and more popular, but until now relatively small databases were realized. Due to the increasing activities on genetic diversity description in grape, the amount of data should soon be more consistent. Analysis of large scale data set is more difficult and until now it has never been accomplished in grape. The 2,919 different varieties of Vitis vinifera from the germplasm collection of ‘Domaine de Vassal’ have been analyzed using 20 SSR markers well scattered in the genome. This database will be very useful in order to decipher kinship relationships if we can handle such database. In the present paper, we tested a methodology for the analysis of large dataset, using FaMoz software. The method enabled the successful identification of parentage for several selected cultivars with known parentage. The fact that our markers were carefully selected on different linkage group added value to the analysis
