New generation of fruit

Ever noticed all the cute fruit at the grocery store? Bought a mini melon cantaloupe - supposedly very sweet. Last year, I had a "x-melon" (kinda like X-Men) which was very sweet but can't remember its name and never saw it. We also saw the mini watermelons which is supposed to be seedless. Then we saw a documentary on the Food channel a couple of days ago and there's this company which sole purpose is to make vegetable taste "better" (sweeter, less bitter, etc.). They use technics like cross pollenation or breeds to create this new type of vegetable and fruit. Interesting...
