Gabriel Hemery reports with Jo Clark on field trials established in 2003 to test five walnut hybrid varieties.  Planted within an innovative silvicultutral mixture, five years on, some have shown outstanding growth.  The relatively fast growth of this hardwood-producing tree may prove to be a valuable component in some new plantation woodlands, particularly short rotation forestry systems.
