Fresh Off the Funny Farm

What do you get when you cross an apricot with a plum? An aprium, of course.

Although you may not have spotted this less-fuzzy apricot, such hybrid fruits and vegetables are increasingly making their way to the produce aisle. Floyd Zaiger, a California geneticist, developed the aprium by transferring pollen between tree blossoms with an eye-shadow brush. Other companies and even the U.S. government are using crossbreeding—not to be confused with genetic engineering—to boost flavor, novelty and nutrition.

Philipp Simon, a geneticist with the U.S. Department of Agriculture, has created purple, red and yellow carrots, each with its own nutritional benefits. But don't be fooled by his ordinary-looking orange carrot: It packs 30 percent more beta-carotene than the regular variety. Simon is now looking to enhance the disease-fighting power of garlic.
