The CTIFL case studies are located in two sites in France: CTIFL Balandran near Nîmes in the South East and CTIFL La Morinière near Tours in the North West. Three species are involved in the project: stone fruits (apricot and peaches) and pip fruits (apple), all three species in organic production. The case study in Balandran aims to develop and sustain the organic production of stone fruits in the region, by providing technical and scientific references and cultural practices that can be used by producers. The objectives of the project are to evaluate, describe and identify varieties of stone fruits suitable for organic farming and corresponding to the commercial expectations of the sector. Organic varietal evaluation has been carried out on peach varieties since 2015 and apricot varieties since 2016. 17 varieties of apricots and 15 varieties of peach (yellow and white peaches and nectarines) are chosen to be evaluated for organic production. The case study in La Morinière is based on the organic orchard of the centre. This orchard was created in 1999 to answer to the grower’s problem. From the outset, producers asked for an assessment of the behaviour of new varieties of apples and pears. For each new cultivar, 10 trees were planted and observed, including diseases and pest sensitivities, annual yield and quality during storage of fruits. There are scab resistant apples and some cultivars tolerant to scab and aphids. There are also varieties without known resistances. In the Loire valley, the most concerning diseases in organic fruit growing are scab and gloeosporium in storage. For pest, the most important issues are codling moth, blossom weevil, aphids and apple sawfly. On pears, problems are blossom weevil and sawfly. Growers are very attentive to yield production and balance of trees. Around 23 new apple varieties in our organic orchard are followed.
