Hi Carolyn,
Looking back, I grew this variety here in Oz in 2009/10 and saved seed from the plant. Now I know the seed would have been from bagged blossoms, as I'm a stickler for bagging for saved seed, which not many do. I can't remember the plant from back then being as bad as the tricot, so maybe it's exacerbated the problem in the genetics. I have a couple more seedlings that aren't as bad. I can only assume that what you're saying about the instability in tricots is what's showing in this plant.
One thing worth mentioning is, that germination was slow on these and I put it down to the age of the seed.
