Are there REALLY so many varieties?
As I look through the tomato seed catalogs, I'm always struck by how many fruit look exactly the same and wonder if most of them aren't the same variety.
I can easily see how, say, a red beefsteak type is bought at a farmstand by a Mr. Richardson who saves the seed and viola - a Richardson's Red Beefsteak is born.
Does anyone know if something like DNA tests are ever run on tomatoes to sort out identicals? I wonder if many of the big yellow/red striped types like Pineapple, Tennessee Sweets and Striped German, for example, aren't actually the same tomato.
