Ich denke in Sachen Verfügbarkeit dürften Davis und Taylor vorne liegen oder hast Du sicheren Zugriff auf die ganze von Dir genannte Liste?
Dann würde mich Deine Quelle interessieren.
Hier mal ein interessanter Beitrag eines Mitgliedes eines amerikanischen Forums:
"I have sunflower, greenriver belle, wilson, davis, pa golden#1, overleese, NC-1, rappahannock, shenandoah, allegheny, wabash, potomac, susquehanna, and have had mango, mitchell, and prolific in the past.
Mango was the fastest growing of all varieties, large fruit, soft flesh and good flavor, very productive and early-mid ripening. Flesh a little too soft for my personal liking.
Greenriver belle has unique very good flavor and the favorite of several people I know. It has small to medium sized fruit.
Sunflower is the latest ripening variety I have, very large fruit and very productive. Has good flavor and texture but sometimes leaves a slight bitter finish on the palette.
Pa golden#1 is early ripening, small to med. size fruits, flavor is fine but nothing to write home about.
Wilson, prolific fast growing. small to med sized fruit, taste is average, nothing special.
davis, productive with med-large fruit, good texture and flavor
overleese, not the most productive but excellent quality fruit that are med-large in size, excellent texture and flavor both when 1st ripened and with advanced ripening. This one takes on a very rich almost butterscotch flavor in later stages of ripeness.
NC-1 My tree has not been very productive but it is the most ornamental tree of them all. The few fruits mine has produced have been on par with overleese, they are excellent and good sized.
Mitchell is okay, nothing special
prolific - productive, fast growing but med-large fruits leave a bitter aftertaste, much worse than sunflower.
shenandoah is like a much more productive overleese - excellent fruit
rappahannock - this produces med-large fruits in my climate with excellent and somewhat unique flavor, ages well. very productive and fast growing tree. The most unique tree has leaves that do not droop as all others. this tree is easy to spot in an orchard because of this trait.
susquehanna, large fruit of excellent very sweet taste, dense texture, would be the best for shipping and ages well, medium productivity.
wabash, productive and excellent, ages well
My potomac is too young but I have tasted it from other trees and it is also excellent."
