Good afternoon everyone, 

after not quite a success with Estimano rootstock grafting,  the Estimano plant that is growing well, will the tomato seeds come true, should I keep them and can use them next year?

Cheers,   Tony

If you mean Estamino rootstock, King's says it's an F1, so you can't save seeds.

Depends what you have grafted onto the root stock. If you have grafted an heirloom variety yes you can save the seeds and the will be the same as the ones you grafted. The plant will not however grow like the grafted one did because it was two different plants.
Just my opinion but while this is the best use of grafting a tomato it allows you to grow a perhaps very tasty old variety that has problems with productivity, diseases and viruses which can be overcome by growing on a vigorous and resistant root stock ... it is expensive... and requires a certain skill level. If you want the same combo you have to graft all over again next year

Good morning to both of you,
Mum I cannot remember if it was F1 or not!
jambop, I think you have the wrong end of the stick, I've planted a straight Estamino plant as I had no other variety to graft and the Estimano plant is 'rather large but few tom' trusses', the seeds will come from that plant and not from the grafted job. I cannot say what the grafted variety is as we liked the tom fried on toast for breakfast we just call it 'the breakfast tom'!. 

Cheers,  Tony.

If Estimano is an F1 variety, you could try rooting a side shoot or two later in the summer and overwintering the plants inside on a windowsill.   Even if they look a bit scraggy by next spring, you could use them for more side shoots to get your root stocks for next year.

I was thinking of doing the same with some of my Crimson Crush and Crimson Blush toms on the plot.  The seeds are expensive F1s and I reckon it is worth a go

Hello new shoot, I shall certainly give it a dashed good try!

Cheers,   Tony.

Yes sorry my bad Tony when I saw rootstock I assumed you were growing a tomato you liked on the rootstock... never heard of anybody growing the rootstock only before as others have said it is F1 so very unlikely to be true to type... that is not to say the plants will not have retained some of the Estimano vigour disease and virus resistances ... may be worth saving the seed and trying a few grafts from the plants?
