Another commenter's mention of shipability is one of the keys. Due to the long supply-chains for modern produce, the fruit or veggie has to be picked early, ripen off the vine and stay firm to hold up to shipping. cf. Grocery store tomatoes, etc. My father is involved with developing the PawPaw (Asimina Triloba) into a commercially viable fruit. It's amazing - as big as your fist with a few black seeds and creamy flesh which tastes like custard. Problem is it doesn't ripen off the tree well and bruises easily in shipping. Various universities have breeding programs and there are some excellent named varieties now but still not quite to a place where they could be commercialized on a broad scale. Another issue is of course people don't like things they're not used to and are generally reluctant to experiment with new foods. (Generalized to the US.) One way to overcome that is through marketing campaigns. Federal Marketing Orders are what we have in place to do this.[1][2] [0] http://www.pawpaw.kysu.edu/ http://www.pawpaw.kysu.edu/ https://www.hort.purdue.edu/newcrop/cropfactsheets/pawpaw.html https://www.hort.purdue.edu/newcrop/cropfactsheets/pawpaw.ht... etc. [1] https://en.wikipedia.org/wiki/Marketing_orders_and_agreements https://en.wikipedia.org/wiki/Marketing_orders_and_agreement...
