One of my Black Krim x Better Bush hybrid tomatoes has cracked.

This is a Black Krim crossed with a Better Bush hybrid?

At any rate radial cracks are common and usually scar over if they aren't exposed to more soil moisture extremes - the original cause - that keeps them opening or they get infected with bacteria and such.

Yes, the crack will scar over. Don't throw the fruit out unless it gets to the point where there's so much mold the fruit begins to rot.

Try to keep moisture consistent as that will prevent future cracking; it doesn't look like you've mulched the container; if not, that will help. You can use almost anything as mulch, including shredded office paper, plain newspaper, or even cardboard.

Thanks guys. I'll mulch it. As for what it is, it is an F1 Better Bush x Black Krim on a Black Krim parent plant. I was hoping to pull some seeds when it ripened.
