Have you checked the tomato sites such as TGS or Totally Tomatoes? Where did you get your seeds? Not sure how much information there is on it, but you might find it with a little digging, lol!

There is another thread here, started by Hudson, not long ago,about

Rapunzel. It might be on the second or third page.

Hi Dirty - It doesn't appear that Rapunzel is bred for resistance to disease. I am growing this variety for the first time in our GH this year. So far - no yellow leaves nor any disease symptoms YTD. The plant is impressive to date - take a look at this link. I will update throughout the season so you should be able to make a decision in part from how the plant performs for us - FYI
