German apple production is facing a variety of challenges. Sustainable production or even ecologization of agriculture and resilience to the effects of climate change are just some of the demands that growers have to face, in addition to growing international competition in the market. In order to meet these demands and to promote all forces involved in apple breeding in Germany, an association of institutional breeders and many of the currently existing private breeding initiatives, the Fachgruppe Obstbau im Bundesausschuss Obst und Gemüse and the Fördergemeinschaft Ökologischer Obstbau e.V. (FOEKO) is aspired, which wants to face the challenges together. The first goal of this association is the realization of the project ApRésKlimaStress. In ApRésKlimaStress, new sources of powdery mildew and scab resistance are to be identified through phenotypic evaluations and genotyping of genetic resources in apple, since only few resistances are available that have not yet been broken. Up to 20 pesticide treatments per season are required in commercial orchards to control these climatically relevant pests, significantly increasing the environmental footprint of production. Breeding cultivars with pyramidized resistance to both pests also using columnar apple cultivars, which allow increased resilience to drought stress, is seen as a way to address the above challenges. Non-host resistance of apple/pear hybrids is also being evaluated as another source of resistance. The goal is to develop low-cost and easy-to-implement molecular markers: KASP assays that can be combined and used by all partners independently, depending on their own breeding strategy. The implementation of the analyses can then be contracted to independent providers.
