Of the hybrid grape tomatoes I've grown the Cherubs, Santa Sweets and Smarty F1. My Fave would be Santa Sweet Sweets.

I know of no one who has dehybridized any of them although saved F2 seeds from Santa Sweets F1 are known to come true about 99% of the time and many folks are on the F6 and F7 and all is well.

I know of just one grape tomato that is OP and that can be found at Tomato Growers Supply, just called Grape Tomato.

I haven't grown it and don't intend to.

Fact is, I don't see anything special about a grape shape, so have other red cherries I prefer to grow and there's a thread here on this first page now, with lots of links to past discussions about cherry tomatoes.

Hope that helps,

Carolyn

Well then, if that's the case, I may give the F2 a shot. Thanks.
