Investigation of varietal characteristics required for sustainable
This was a
DEFRA funded research project carried out in collaboration with NIAB.
The purpose of this study was to provide DEFRA with a review of our
current understanding of variety characteristics that may be valuable
in the context of existing and sustainable agricultural systems
(e.g.'treated', 'untreated' and organic). This was combined with a
review of physiological research that will allow these characters to be
broken down into components that can be measured as part of a practical
VCU (Value for Cultivation and Use) test.
simultaneously eliminating components of these VCU tests that are
inappropriate to the intended agricultural system, it is now possible
to produce a more flexible VCU framework which ensures the selection of
a wider variety of cultivars appropriate to the increasing diversity
