Can someone tell me which is the least frost hardy variety? And which one probably makes the most zygote seeds?

C-35 clearly has the most zygotic seed at +/- 15%. Troyer and Carrizo are ,5% to 2% maximum. C-35 hardiness is contingent on gradual exposure to cold, therefore there are reports of being resistant against cold as well as being cold sensitive. I have no experience with Carrizo/Troyer cold hardiness.
During the past,very mild Winter most C-35 seedlings survived, but made very little growth until mid-summer. This was following a Winter low temperature of -12C (+10°F).
