Even assuming that cucumbers or peppers could be genetically engineered to taste better, the economics of GM crop breeding are just tough. Though the price of GMing crops is dropping, it's still higher than traditional plant breeding. For specialty crops, i.e. not corn, soy, or the cereals, it hasn't made a lot of sense to take the plants to market for three main reasons: 1. Specialty crops are smaller markets, so there is less money to be made; 2. Specialty crops require more money invested in the growth of the plants relative to the investment in seeds; 3. Big cash crops like corn are often grown as a monoculture, which makes the plants more susceptible to pesticide-resistant bugs than specialty crops, especially when farmers grow a certain crop over and over in the same field. So farmers are more inclined to spend the extra money on genetically modified seeds to protect them.
Social factors have also driven costs up. The big food processors are worried about consumer backlash and most European countries have closed their markets to GM crops. As GM advocates point out, the extra regulatory hurdles also add to the cost of bringing a GM product to market.
What the biotech industry is waiting for is a breakthrough -- something that would be so great that consumers would flock to it, overlooking (or not even noticing) its breeding technique. What would this product look like? It's hard to say, but I had several sources tell me to look for it in melons some time in the next few years. So, keep your eyes on the melon aisle, regardless of which side of the GM crop debate you're on, says Alexis Madrigal, writing in Wired News.
