Evaluation of needs and priorities has been ongoing in the current RosBREED project: • Information of trait values from stakeholders
(Obj. 1 of RB1)
• Information of MAB breeding needs and opportunities from breeders (Obj. 5 of RB1)
• Input from Advisory Panel Members(Obj. 5 of RB1)
Direction from Feedback
![Page 3: From Natural Diversity to Better Cultivars 10 January 2013 San Diego, California](https://reader038.vdocuments.us/reader038/viewer/2022110323/56649d8b5503460f94a72f2c/html5/thumbnails/3.jpg)
Feedback Received
• Industry:Risks and opportunities indicate a need to broaden the scope of traits while making sure that fruit quality is still a top priority
• Breeders:MAB adoption has begun, but breeders need help (access to routine accurate genotyping services, genetic knowledge for other traits, implications of trait locus clusters, and knowledge of genotype × environment interaction)
