  1. OBJ. 1 TRAIT AND MARKET SEGMENT BREEDING TARGET ESTABLISHMENT Year 3 Deliverables, Challenges,Year 4 Goals

  2. Goal • Help accelerate and increase efficiency of cultivar development and adoption by identifying valuable breeding trait targets • Objectively identify important breeding trait targets • Prioritize the most valuable target trait loci for the development of DNA diagnostic tools RosBREED

  3. We like firm tart cherries that pit well! What trait is my next breeding target? We like disease resistant apple trees! I like tasty strawberries!

  4. Year 3 Deliverables • What • Grower and market intermediary survey data – relative values of fruit quality and production traits were obtained • To whom • U.S. Rosaceae industry & breeders • Impact • Trait values obtained are being used to prioritize traits for development of DNA diagnostic tools RosBREED

  5. Year 3 Deliverables • What • Consumer’s preferences and values for targeted fruit quality attributes – elicited • To whom • U.S. Rosaceae industry & breeders • Impact • Trait values obtained will be used by breeders to assign trait priorities; industry sectors have knowledge of relative consumer values RosBREED

  6. Challenges and plans for tackling • Elements in the choice experiment scenarios not absolutely clear (e.g. individual interpretations of flavor and sweetness) use a consensus approach to interpret the data • Logistical challenges in providing apple samples that met criteria for the consumer auction experiment help from the WTFRC(demonstration after lunch!)

  7. Year 4 Deliverables • What • Trait priorities for market intermediaries, growers, and consumers of apples - analyzed, interpreted, and communicated • To whom • MAB Team and Rosaceae community Impact intended • DNA diagnostic tools will be developed for the most valuable fruit target trait loci, thereby increasing breeding efficiency for high priority traits
