Phenotypic and genotypic data of a European beech (Fagus sylvatica L.) progeny trial issued from three plots along an altitudinal gradient in Mont Ventoux, South-Eastern France

We provide extensive phenotypic and genotypic data for 5813 seedlings of European beech (Fagus sylvatica L.), raised in a progeny trial from April 2010 to May 2012. Seedlings originate from 60 open-pollinated families collected in three plots at different altitudes (N1: 1020 m; N2: 1140 m; N4: 1340m) on Mont Ventoux, South eastern-France (44 ˚ 11’ N; 17 ˚ 5’ E).
