Goss, I've communicated with Mike Hotchkiss of USDA/NCGR in Byron, GA who manages a small collection of pomegranates at the repository there. In 2010 he included the following comments in one of his emails to me which should be useful in you when selecting varieties to try. (Chris's R-8 was tentatively identified as Salavatski, btw.)
The ten cultivars I recommended to Chris were somewhat arbitrarily selected because they had mostly survived two severe freezes (OF and – 6F in Dec. 83 and Jan. 85) and were able to produce a few fruit under our humid conditions. The ten are listed below.
Mejhos 6269, Salavatski, Kaj-acik-anor, Sejanec, Apseronski krasnyj, Afganski, Apseronski, Saartuzski (Yalta), Surh-anor, and Entek habi saveh. Chris got rid of 6 of these and has kept 4 cultivars with his R-8 being his favorite. I sent fruit of Chris’s R-8 to Jeff and he tentatively narrowed it down to 2 but I cannot find the names. At that time Jeff said his favorite of the Byron material was Al-sirin-nar (R-6).
All of the pomegranates that survive at Byron should be considered relatively cold hardy. Fruit quality comparisons are best taken at Davis. Hope this answers your questions.
