If blackberries cross, does it affect the current berry's flavor?

General Fruit Growing

If I understand, when you cross a plant, it is the seed and the subsequent plant that would come from that seed which would be the result of the cross. But, does it affect the current berry or fruit?

If I plant a Ponca next to a Kiowa or some other set, these are random here, will the Ponca or Kiowa taste right? Will they taste different on these than if I only had the single cultivar?

I thought about getting different kinds to test, but I don’t know if they can be planted next to each other without affecting the taste of the berries.

Thanks for help.

Not generally, but there are exceptions.

Some fruiting plants will grow fruit to maturity without fertilization. The seeds, if any are sterile. If fertilized, they produce fruit with seeds that are usually fertile and the fruit has a different flavor profile.

I learned here recently there are also hybrid annuals (e.g. sweet corn) which require a specific pollen source to produce the desired taste.
