Budding Pecan Tree Growers Can Learn about Native American Crop
|Each spring, Tommy Thompson dresses in a "space suit" and visits 6th-to 8th-grade classes in his hometown of College Station, Texas. Dr. Thompson does this because he's a mentor--a teacher who helps young people learn new and interesting things.
His hobby is beekeeping and he shares what he knows about bees with young people. The space suit he wears is actually a special suit to protect him from bee stings. His real work is breeding pecan trees in the only national pecan tree breeding program in the world, operated by the U.S. Department of Agriculture (USDA).
Pecans, produced by the trees, are a native North American crop. Early Graphic of Native American dancer. Native Americans, as well as European settlers, harvested pecans by throwing sticks into the trees, knocking the nuts to the ground. There, pecans were free for the gathering.
Today, pecans are a multimillion-dollar industry. Rural landowners in the Southwest and Southeast grow pecan trees in large groves or woodland pastures. In 1999, U.S. pecan production was about 342 million pounds and worth nearly $448 million. Georgia, Louisiana, Texas, New Mexico and Arizona are the top five pecan-producing states.
The pecan industry depends on new tree varieties being developed by plant breeders like Dr. Thompson, who works for the USDA's Agricultural Research Service (ARS). These scientists make improvements in the trees to help them overcome diseases.
All ARS pecan varieties are named after Native American tribes. The most recent tree released is Nacono. Nacono's parents were pecans named Cheyenne and Sioux, both well known for their high-quality nuts and resistance to a disease known as scab.

That, in turn, will help protect the environment. A Nacono pecan tree produces a large, high-quality nut. And it grows well in the eastern United States and in many other pecan-production areas of the world.
ARS doesn't give out trees, but does provide material called graftwood to nurseries. Nursery operators in turn produce budded trees for sale to homeowners and commercial growers. It usually takes 2 to 3 years after a new variety is released before nurseries are ready to sell trees to the public. USDA does include seedlings of new varieties in the ARS National Plant Germplasm System (NPGS). That's so these new varieties can be available for research purposes, including development of trees that your parents can buy from a nursery near your hometown.
Here are some interesting facts about pecans:
* On his deathbed, former Texas Governor James Hogg asked that a pecan tree be planted at the head of his gravesite, instead of a marble or stone monument. He died on March 2 (Texas Independence Day), 1906. Pecan is now the state tree of Texas.
* Astronauts took pecans to the moon in two Apollo space missions. Pecan wood is used in agricultural implements, baseball bats, hammer handles, furniture, wall paneling, flooring, religious carvings, and firewood.
