PME-VG-06 CALIFORNIE

The main interest of this seed orchard lies in its resistance to summer drought. The basic material comes mostly from northern California, an area subject to dry summers. The clones were then selected in the south of France, again under conditions of severe summer drought. The counterpart of this adaptation is an earlier budburst, which allows trees to grow before the onset of drought. The selection has, of course, also focused on vigor and form.
