What Rick Corey says is pretty accurate with one exception.... did anyone catch it from Dave and Trish's last ATP podcast "Let's talk Tomatoes"?
Unlike most tomatoes, potato leaf types have floral sex parts (stamens and pistils) exposed. For these, cross pollination is quite easy.

>>>Does the tomato itself need sun, or just the plant?

Seeing as how the traditional method of ripening green tomatoes (that are picked before a killing frost) is to wrap individually in newspaper, I'd guess that light is not required.

Rick Corey said:P.S. I have often wondered: one bloom produces one fruit. Does that mean that "one bloom uses one pollen grain to produce one fruit"? So that all the seeds in any one tomato are either all self-pollinated or all cross-pollinated by the same pollen donor?

or does each bloom use MANY pollen grains to produce its many seeds, and each seed MIGHT be cross-pollinated by a different pollen donor?

And is it the same for every species, that all the seeds in one pod came from one pollen donor? or do different plant species work different ways?

A barrel of questions that ought not be answered here, in my opinion. We're supposed to stick to the original question.
Maybe post in the Propagation forum?
