I thought this, too. Until this spring old seeds were the only place I had seen it. But I had several show up in my dwarf project seedlings. And those were all fresh seeds.
I am sure age is one cause, but it can't be the only one. Maybe this adds to Craig's theory of damage to the seeds in the mail by the equipment they are using.
I picked the first tomato today from my last dwarf plant to have ripe fruit. It was way behind because it started out blind. I kept it going until it decided to put out growth. It will be interesting to see what the plants from these seeds do. Could there be a genetic component to it?
