Sweetpotato Cooking Quality Consultant

I. Background
RTB Breeding for Quality is a part of the broader RTB breeding project that comprises activities aimed at integrating processing and eating quality of boiled sweetpotato in routine breeding, continuing the progress RTBfoods project (2018 – 2023) achieved.
