Four orchards having peach and apricot trees are studied. They encompass a large variety of experiments to understand the challenges of agroecological practices in the framework of global warming and increase of pests/diseases. They are all managed by INRAE UR A2M.

“DIVAE contributes to the understanding and prediction of the effect of climate on the biology of various fruit species (apricot, cherry, peach, apple) with 5 varieties covering the range of earliness for each of the 4 species. It has 6 sites spread across France: Angers, Bellegarde, Clermont-Ferrand, Gotheron, Mauguio and Toulenne, all under different environmental conditions. Globally, it focuses on phenological traits, the study of the seasonal rhythms of living organisms determined by seasonal variations in climate. These observations on fruit trees are part of TEMPO, a national network of observatories dedicated to the phenology of the entire living world (plant and animal species, farmed and wild)”

“Exploring the genetic determinants controlling quantitative resistance to multiple pathogens remains a priority. The core collections available in the unit and their genomic characterization are perennial and valuable resources for investigating the question of plant resistance. How are resistance laws distributed across the genome and organized on a finer scale? Are there genetic determinants that control several pathogens or act as functional hubs ? It is in this context that we are conducting GWAS studies (genome-wide association study) to identify the genetic determinants controlling quantitative resistance. The aggressors considered are oomycetes, necrotrophic and biotrophic fungi, insects, nematodes, viruses, bacteria and a phytoplasma.”

“EcoPêche uses a partnership-based, multi-site approach to design, evaluate and transfer the foundations of innovative peach-nectarine orchard cropping systems that reconcile a significant reduction in phytosanitary products and inputs, the production of high-quality fruit, and technical and economic performances that ensure the sustainability of farms […] Seven system trials have been set up at different sites: Inra PSH Avignon (84), Inra Gotheron à Saint Marcel les Valence (26), Inra UE Arboricole – Domaine de Bourran (47), Ctifl Centre de Balandran (30), Stations d’expérimentation SEFRA à Etoiles sur Rhône (26), SERFEL à Saint Gilles (30) et Sica CENTREX à Torreilles (66). At each site, a cropping system representative of current practices (the reasoned system) is compared with one or more prototypes of input-efficient systems, and in certain situations with an organic farming system […] The aim of the EcoPêche 2 project is to continue evaluating the multi-criteria performance of phytopharmaceutical-saving peach-nectarine orchards designed and planted as part of the EXPE EcoPêche 1 project (2013-2018). It will also explore the feasibility of new, highly ambitious agro-ecological and technological systems.”
