What is causing the seeds in my golden tomatoes to turn black?

The outside of the fruit looks fine but when I cut it open the seeds are black and it also looks like their may be mold in there. So far, 5 of the 6 fruits I harvested were affected. I have 2 other types of tomatoes in the same bed and they are doing fine. Last week I found a horned tomatoe worm but I'm not sure which one of the plants it was on. The variety is "Golden Jubilee".

Answers:
It sounds like the secondary stage of blossom end rot. The cause of this disorder is a calcium deficiency in the developing fruit. Extreme fluctuations in moisture, root pruning and excessive nitrogen fertilization can also enhance blossom end rot. In the secondary phase the interior of the tomato becomes infected and may turn moldy. The other possibility is something called Buckeye Rot under moist conditions, a white, cottony fungal growth appears on the inside of the fruit. With time, the entire fruit will rot. The fungus does not affect the foliage. The disease is most common during periods of prolonged warm, wet weather and in poorly drained soils. The fungus survives in the soil and is spread by surface water and rain. Peppers are also susceptible to this disease. Ive grown Golden Jubilee and they are not a hardy tomato although quite good.

sounds like you might have blossom end rot. Usually brought on from high humidity and over watering. In time the whole plant and all the fruit will be affected. You may be able to salvage a few fruits from the rest of the plants before it takes over.
