I grew these F1s last summer. I crossed Cherokee Purple and Pineapple varieties.
I used pollen from CH Purple with Pineapple female and then I also crossed using Pineapple pollen with CH Purple female.
The photo above and two below are the CH Purple pollen donor. They ripened well over a week before the Pineapple pollen donor did.
Other than that, They were perfectly similar in taste (fruity), appearance, size(very large), color and productivity (high).
I can spare 10 seeds per person for a limited number of people. All I ask is that you do attempt to plant and cultivate 2 plants and that you post results. If you get anything real nice or different, it would be nice to get some seeds back.

These ripened later than the CH Purple donor. In fact you can see that I couldn't wait and picked these while not exactly ripe.
Not completely ripe.
