Just the other day I was very surprised to find out that my F2 crosses I’ve made from Emery’s Seeds and I’ve stored for long years in sealed package in freezer germinated really well. I’ve moved few times so they were unfrozen about 2 or 3 times during the years and then frozen again.
Seeds stored this way since 2000 have got incredible 95% germination rate!
I wish you luck with them!
