Where can I find disease resistance info for heirlooms?

I have had phenomenal results with grafting onto resistant rootstock to prevent fusarium. I found that the best rootstocks were the ones resistant to all three races of fusarium which I obviously have since no tomatoes resistant to just two do very well for long.

I have found some heirloom tomatoes to be far more resistant to fusarium than others and have found many that have absolutely no tolerance to it. Below are some that have shown the best tolerance. All of them will eventually get it but they have enough resistance to usually produce at the least a decent amount before they get too sick and wilt completely. The ones with the star after them have done the best against fusarium of the heirlooms and the ones with two are the ones that have done the very best.

I'm sure there are some i am leaving out but these have been more successful than most the last few years despite rampant fusarium in my garden. I still always plant plenty of replacements because if I see a plant has fusarium before it has good sized tomatoes already then I will pull it and replace it.
