A decline in overall potato consumption has Texas A&M AgriLife Research breeders working on "designer" spuds that meet the time constraints and unique tastes of a younger generation.
Dr. Creighton Miller, AgriLife Research potato breeder from College Station, Texas, recently conducted the Texas A&M Potato Breeding and Variety Development Program field day at the farm of cooperator Bruce Barrett south of Springlake, Texas.
"Potatoes are an important delivery system for nutrients to humans," Miller said. "The average consumption in the U.S. is 113 pounds per year per person. But overall potato consumption in the U.S. has generally declined somewhat.
"So what we are doing now is developing unique varieties that have a tendency to appeal to the younger set with high incomes who are willing to try something different," he said. "This has contributed to an increase in consumption of these types over the russets, which are still the standard."
Miller said the objective of the Texas A&M potato breeding program is to develop improved varieties adapted specifically to Texas environmental conditions.
"However, some of our varieties are widely adapted across the U.S.," he said. "Three of them collectively represent the fifth-largest number of acres certified for seed production in the U.S., so we've released some successful varieties, and we are developing more all the time."
The Texas Potato Variety Development Program currently has 412 entries at the Springlake trials and 927 entries at the Dalhart trials. Additionally, the 2014 seedling selection trials at both Springlake and Dalhart include 115,408 seedlings from 634 families or crosses.
One selected Best of Trial at Springlake this year is BTX2332-IR, which is a round red potato. And, Miller said, the traditional russet potatoes will always be a mainstay, as they are used primarily for baking and French fries. Also in the trial is the standard white-skinned variety with white flesh used for chipping purposes.
"We are always interested in new and improved red varieties and russet varieties, but there are some other types that have become more interesting lately," Miller said.
One type is a small potato, he said, adding that within the trials he is looking for varieties with a heavy set of small potatoes.
"One of the reasons for the popularity of the smaller potato is with both spouses working, the amount of time required to prepare potatoes becomes an issue with some people," Miller said. "With the small potatoes, they can be microwaved very fast and be on the table in a hurry."
Other varieties catching more attention are red potatoes with yellow and white flesh and the purple-skinned potatoes with yellow flesh, he said.
The tubers with yellow flesh contain compounds that are antioxidants, and that appeals to the health-conscious consumer, Miller said.
"So in addition to having the unique appearance, they are healthier potatoes to eat," he said.
And this year, Miller also has specialty potatoes with splashes of red and yellow on the skin and have a yellow flesh.
"These are referred to as gourmet potatoes, and that niche is receiving more emphasis lately," he said. "These are generally boiled and add unique color to the plate when served."
But Miller was quick to say the russet potato is still the primary emphasis of the program, and a new russet being grown by the Barrett family will soon be released for commercial production.
"It promises to be very successful," he said.
