My neighbor sells tomatoes from his tailgate at many different locations locally. He plants over 500 tomatoes and has been doing this for a long time. He has sold many diff kinds but has settled mostly on Goliath hybrid which is a round red 10-12 oz fruit, very smooth and uniform. He is in business so he must feel this is the one that sells the best. Last yr he had some Bearclaw which were pink and averaged about softball size but he relies on Goliath.

Yeah it depends on the location of the market and how adventuresome the buyers may or may not be. Some will only buy round, red, and medium sized. Some will buy a few yellows and only a few will go for any of the other colors or shapes or sizes.

You can get a wide range of what works where over on the Market Gardeners forum here.

I had really good production from Sioux last year, considering how hot it was. It did the best of the full-size tomatoes. They are orange-red tennis-ball size or larger. They have a good flavor, but they're not sweet. I live in NE OK.
