> the point is preservation of heirloom varieties that are precisely not interesting to commercial growers
The problem is that is not realist. This is definitely NOT how we will preserve heirloom varieties. Each variety needs their own tree not a stem. Trees discard its stems all the time so in 5 years most ot your varietes will dissapear. Has happened before with old cherries.
The idea would be like trying to save dog breeds putting a collection of dogs from all breeds (shih tzus, mastiffs, chihuahuas and great danes) in the same room and competing for the same food
