The Sarvari Research Trust successfully bred seven varieties of blight resistant potatoes which span various cropping and culinary genres. In 2013, Sarpo Potatoes Ltd was established to be the trading arm of the Sarvari Research Trust. It has since been awarded funding from the Welsh Government Rural Development Programme (RDP) through the Co-operation and Supply Chain Development Scheme pathway. The funding aims to develop clusters of growers of virus and blight resistant seed and ware potatoes to help satisfy increasing demand in the marketplace. The project will also facilitate training on production, and provide access to specialist machinery. By explaining and demonstrating their benefits to ware growers and customers, the project also aims to expand the market for Sarpo varieties.

The three-year evaluation conducted by Miller Research monitored and assessed the success of the RDP funding in achieving its aims. The project was a three phased approach through a baseline evaluation, mid-term and final evaluation. At each phase of the evaluation, Miller Research engaged with stakeholders through interviews and an online survey, analysed available monitoring data, and held workshop sessions with the growers. This engagement allowed for a final evaluation to assess how the funding has contributed to the development of the horizontal and vertical supply chain of seed and ware potatoes in Wales.
