Confused about Black from Tula

tuttamatta · April 3, 2009

I hope that somebody will solve this mystery:
last year I saved seeds from Black from Tula (I purchased the plant at a local well known nursery), since I liked it a lot, I planted a lot of seeds and 25% of them are showing potato leaves, the rest have regular leaves.
It should have regular leaves, right?
So, now what do I do?
Should I save seeds from both (when I have tomatoes...) or only from the RL?
Also, this year for the first time, I'm planning to have a plant sale, so can I offer the PL Black from Tula as such or should I keep them away from selling them?
Still confused, HELP!!!!

Sounds like the plants you got last year were crossed - and you are seeing segregation typical of an F2 generation. You really can't call them PL Black from Tula - since they will be very variable.

To clarify a little bit. You cannot call any of the seed/offspring "Black from Tula". The 25% ratio indicates that the seed came from a hybrid plant/plants, and potatoleaf is just one of millions of altered genes occurring in all of the offspring seed regardless of leaf shape.

How fun! Plant several and see what you get! I don't think you should sell them though

Thank you all for your comments.
I understand that I should not sell the PL, but what about the RL, can I trust those plant to be like the original plant?
Or should I hold them back too?

You probably can't trust them to be uniformly like the intended, since if it was indeed seed from a hybrid, anything is possible.

What they are saying is that if all of the seeds came from
the one plant, and there are PL seedlings, then that plant
was already crossed (an F1, likely a chance cross between
Black From Tula and an unknown PL; the F1 leaves would
still have been RL).

So all of its seeds will be hybrid seed, whether the seedlings
are RL or PL. The results at harvest time are unpredictable,
and the RLs will not be Black From Tula either. (You could
call them Black From Tula X Unknown PL F2, but that is
probably not something that you want to give/sell to
unsuspecting new gardeners, who would be better served
by something more predictable.)
