Evaluation et homologation de variétés issues des vergers à graines de l'Etat - Programme 2016

Abstract : This report shows the work done in 2016 by Irstea, INRA, ONF and CNPF in the frame of a joint research programme dedicated to improved variety testing. Three species or groups of species are involved: Douglas-fir, larches and ash. With regard to Douglas-fir, the actions aim to enlarge the common network of comparative trials and compare the performance of the 8 French varieties for survival, health, growth, branching, cold hardiness and drought resistance. For larch, the results mainly concern the performance of hybrid varieties at the adult stage (12 to 20 years after planting). The studied traits include survival, resistance to heat and drought, growth in height and diameter, stem straightness, and resistance to larch canker. The work dedicated to ash mainly concerns resistance to Hymenoscyphus fraxineus.
