Found a wonderful Open Access source https://pub.epsilon.slu.se/35064/1/duric-g-et-al-20240916.pdf in Sweden. That seems to be doing good work researching Apple germplasm stocks in neighboring countries as well. In this study; they are exploring the apples growing in Bosnia/ Herzegovina. Finding origins and a not surprising web of apples with somewhat the same dna profile. One listed under 13 listings!!!
Anyway I find these projects enlightening; especially being an obvious epicenter in ebbing and flowing Apple production.
