2014.09: Selection of 16 varieties for the field experiments

The meeting first allowed summarizing data collected on the variety panel by the different teams, removing redundant or less informative data, and building a matrix of key traits for the varietal selection. Each key trait has been associated to one or several ecosystem services (eg: % soil cover associated to weed control). With this synthetic matrix, multivariate analysis (Ward, DAPC) identified 4 clusters in the 60-varieties panel. These 4 clusters are coherent with existing genetic groups (Magic varieties, landraces, elite varieties). The final selection of 16 varieties will balance the contributions of these 4 groups!
