The point is he has grown this variety for 25 years at a latitude of 64 deg North which the variety has become acclimated to.

To quote Tom Wagner from his post in the above mentioned thread;

[Anytime someone keeps a variety isolated from others for an extended time, the tomato variety should be considered unique in many ways.

As a plant breeder, I have deep respect for varieties grown in a particular region for a long time. Acquired characteristics, adaptation, bottle necking of the germplasm, small mutations, elimination of the original bulk population diversity, the template of Fairbanks, Alaska growing conditions is a valid point of identity.]

Now of the many varieties you have that will go down to 35 deg F., how long will they stay at that temperature and will they grow in Fairbanks Alaska to maturity outside, unprotected!
