| Abstract:
Most of today's apple cultivars are susceptible to scab (Venturia inaequalis) and powdery-mildew (Podosphaera leucotricha). The use of large amounts of fungicides in orchard raises ecological problems, consumer's health concerns in addition to the economic cost. The D.A.R.E. project aims at developing knowledge, methodologies, plant and pathogen material to achieve durable genetic resistance towards these pathogens in the future. The resistance/susceptibility of European cultivars towards several V. inaequalis and P. leucotricha inocula was assessed. A large part of this plant material showed partial or complete resistance to numerous | |
