1. GF at CIP Current state and outlook

2. Goal Perform IMPACT IT with focus on potato and sweet potato Take into account heat and drought resistance Middle run: diseases

3. Current state At the beginning Ongoing work on crop modelling Beginning cooperation of breeders and crop modelers Initial stage of work with IMPACT

4. Activities ahead A dual track approach: Economic modelling: IMPACT training in May Gain understanding of modeling of potato and sweet potato Identify directions for necessary improvements (parametrization, code) Perform simulations Integrate VCM results Carry out simulations Crop modelling: Further develop crop modeling with CIP models VCM process (model improvement, parametrization, itraits, data gathering) Cooperation between breeders and crop modelers Carry out VCM simulations
