Are they fruity or are they tomatoey?
There are two flavor profiles for yellow it seems, those that if you closed your eyes you wouldn't know it is not a red tomato, and those that are... fruity. I like the fruity ones.
I've been working on a yellow breeding project looking for a medium sized fruity determinate.. grew out five F2s this season, only one fruity, one nice determinate but it wasn't fruity.
Maybe you can save me the trouble?
