From the BBC news article titled How farmers and scientists strive for more flavour, which discusses a company named Pairwise that is using CRISPR technology:

Pairwise's first product, expected in a year or two, will be a seedless blackberry it says will have a more consistent taste than traditional varieties. It is also working on a stoneless cherry.

All this could be done through traditional breeding techniques, but as fruit trees take years to mature it would be a very long-term project.

"Some of the fruits we're interested in, like cherries where we want a pitless cherry, theoretically you could do it with breeding but it would take 100-150 years," says Mr Baker.
