Do you mean two tomatoes turned out off type on a plant that was otherwise on type with multiple other on type tomatoes or two plants produced multiple tomatoes that are off type? It is the difference between crossed/mixed up seed and a sport. Probability wise we would assume crossed or mixed up seed.

Good luck.

gld, agree with Randy and wanted to ask the source of your seeds for Granny Cantrell.

All seeds came from Baker Creek Heirloom Seeds. I seem to remember getting one pink tomato from one of these plants, but I could be wrong.

I will be watching closely all the rest of the fruits.

I thought maybe the wrong seed, but couldn't find a similar fruit when I Googled for green tomatoes.

BCHS seems to be having a history of this however,

our region (and much of the middle midwest) has had an unusually wet and cool weather pattern which has created all kinds of problems due to all wet weather. I am seeing this everyday on all kinds of plants.

I have seen something similar to what you show on my tomatoes which were not planted in raised beds.

What I suspect is the uneven ripening due to nutritionally related issues from the wet weather.

Here is what I suspect has occurred in areas where plants didn't get good drainage.

All that heavy rain early on (May-July) caused the finer feeder roots to be stunted or die due to lack of oxygen. As the plants grew the root growth wasn't balanced with the top growth and they weren't taking up all that they needed. Earlier on (with tomatoes) lots of people saw leaf curl which was a sign of this occurring. As the fruit matured and the roots played catch up they probably lacked potassium and some if not most of the potassium applied could have been leached.

So what you are seeing might also be a ripening issue.

In our region other plants such as spruces or normally drought tolerant plants that seemed fine earlier this season are now having a really hard time because of this phenomena.

One of the extension people from Kansas also wrote up some about this on landscape plants. Again this happened to my tomato plots where I didnt plant on raised beds.

Overall we still seem to be having cooler weather than "normal" in our region but the hot humid weather of about 2 weeks ago is showing its stress effects now on all kinds of other plants besides tomato.

It might help to apply some kind of water soluble fertilizer to help the rest of the fruit that are developing. Seaweed/kelp would be one source as well as potassium nitrate or some of the "blue stuff" to apply something which will be quickly and readily available.

Please keep up posted as to what happens with later fruits.

Crossed seed is becoming more common among heirloom varieties regardless of which seed supplier they came from. I would estimate the incidence of over 5% this year of the 800+/- plants I have growing.

I have red and pink Black Cherry fruits, Snow White Cherrys the size of golf balls, and only half of my 12 Copia plants are producing fruits that are as I would expect. One plant even produces yellow oxheart tomatoes. So whether you decide to save seed or just keep buying as I do you can expect more of what you are experiencing.
