An annually identical assortment of each of 32 winter wheat varieties and lines bred
under conventional conditions was tested between 2004 and 2007 both in a
conventionally and in an organically managed environment. Previously the assortment
had been evaluated with respect to yield and indirect parameters of baking quality.
The objective was to obtain evidence for a targeted selection of lines for their later use
as bread varieties in organic farming. It was discovered that for a successful selection
of lines for the subsequent cultivation under organic conditions especially the
evaluation of yield must be conducted strictly under the same conditions
