And what if we accomplish the same end result through selective breeding, as is common today?

It seems highly unlikely that selective breeding would result in tomatoes that have significant levels of useful vitamin D.

I don’t find that unlikely at all. Tomatoes are very susceptible to improvement through selective breeding. Test for vitamin D each generation, plant seeds from the highest.

Tomatoes have 0.00 micrograms of vitamin D though.

[UncleOxidant]

And as the article pointed out that's not actually vitamin D, but a precursor to vitamin D and most of that small amount is in the leaves not the fruit.
