There have been polyploids in the past, but whether there are any still in exisence is the bigqer question, and I'd have to do some Googling and check my faves to try and answer that question,along with the possible advantages and disadvantages of being polyploid.

Thanks,it would mean a lot to me if we could identify wich ones are polyploid(and ploidy number).Surely there ought to be at least a couple,maybe even some of the common ones everyone grows are,but we just don't know.

Yes,unfortunately...I came across a pdf that discussed this topic and it seems tetraploid tomatoes are actually not what I thought they might be.Some plants exhibit increased size and vigour with doubling of chromosomes but that's not the case with the tomato I guess.
