I bought Yellow & Red Beefsteak Tomatoes from the Grocery Store & found Fish Bone like Fibers inside the fruit. Is this normal for Beefsteak (I never noticed it in Cherry or Roma Plum types)? I only found them in the core, they have a firm plastic spoon or fishbone like texture & hardness. ![image](https://canada1.discourse-cdn.com/flex031/uploads/landracegardening/original/2X/c/c86bcdc037a52a6d6a06de5f8a41db575eda74f7.jpeg) Here’s what the fruit in question looked like. This happens in Red Beefsteaks as well. ![image](https://canada1.discourse-cdn.com/flex031/uploads/landracegardening/original/2X/6/62df772258dd0eb6b1e985707682db888b26ef19.jpeg) I really find them annoying & would select against this trait, but would I also be selected against big size by doing so? Do all beefsteak Tomatoes have Fish-bone like Fibers in core or are there varieties without fish-bone fibers? ---

I also found Heriloom style Greenhouse Grown Tomatoes being sold at my local Grocery Store. I don’t think they have Fish bone Fibers in their core but haven’t tried them yet to confirm. ![image](https://canada1.discourse-cdn.com/flex031/uploads/landracegardening/original/2X/3/3fd50d1630bd585eae983d9f4bb3eb1a139d0a15.jpeg) ---

I’ve grown a lot of heirloom and beefsteak type tomatoes and I’ve never seen or heard of anything like that. ---

Interesting, so is it just a grocery store tomato thing (I don’t garden so I wouldn’t know)? Grocery Store Tomatoes are bred for hard skin to reduce bruising during shipping, is the fishbone fibers simply a consequence of selecting for hard skin trait? ---

The tomato in the first picture just looks like a grocery store tomato on the outside, but I don’t even have a guess about the weird growth inside. The ones in the second picture look like real tomatoes as far as colors and shapes but they have that plastic looking sheen typical of greenhouse tomatoes. ---

First tomato is greenhouse grown. Thank you for confirming that this isn’t a common thing. All the other tomatoes are also greenhouse grown, I think they bred more heirloom looking types since demand for heirloom tomatoes is increasing.
