There is currently quite a bit of controversy about cloning and other genetic possibilities. Some are anxious about the potential of preprogramming human offspring. The obvious ethical questions could be discussed at length. But when discussing the manipulation of plant genetics there is quite a history of benefits. Plant breeding's main aim is to develop improved varieties. The improvements include resistance to disease, insects, greater yield, better quality, and heartiness to weather conditions.

It would neglegence not to mention that plant breeding also exists from a profits basis. Seed companies can find a better market when they have a new or better variety to offer. Companies want to be the first to produce a new strength in a plant species because the Plant Variety Protection Act affords marketable benefits.

Another reason why plant breeders work to develop new varieties is intellectual curiosity. Although a new cultivar may not be developed, other scientific knowledge is gained when forage traits are selected and studied.
