I recently read at Johnny's that they are introducing (next year, if the dates posted are correct) a "new" old strain of Wisconsin 55. It piqued my interest because WI55 supposedly has some tolerance to Septoria.
A University of Wisconsin worker had frozen seeds of (or close to) the original strain in the 60's, and it had been successfully germinated to be re-introduced
next November.

I've certainly heard about storing seeds in the freezer, but had never heard anything about really long-term storage that way. Searches didn't produce anything very meaningful. Anyone have any other information about long-term freezing of tomato seeds?
