Hi Carolyn, thanks for your reply.
The crosses I've been working on are described in my posts, most recently Hilberts Grand Tomato Hotel ( the place where there is always room for more guests, even if it's full
)
I understand what you're saying re wide vs narrow crosses, some of the crosses described are not close to the goal but a few are actually pretty close to what was aimed for.
Also some are at F3 and not at all stable, one is at F5 but not as stable as I hoped... etc.
It is a baffling process and full of surprises, so I'm hoping for some general insights about the stability of the additive or QTL traits, and how to reckon how many plants to grow when there isn't a simple recessive/dominant to select for.
