University of Arkansas licenses 2 long-grain varieties to Erwin-Keith

The University of Arkansas System Division of Agriculture has licensed two commercially released rice varieties to an Arkansas seed company that will market them to growers in time for the 2021 growing season.

The long-grain rice varieties, RU1701081 and RU1701084, will be available from Erwin-Keith Inc./Progeny Ag, based in Wynne.

“RU1701081 has traditional long-grain cooking quality, low chalk and can withstand the common rice blast races,” says Dr. Karen Moldenhauer, University of Arkansas rice breeder. “It has a very similar yield to LaKast.”

RU1701081 was not released because it would have duplicated the advantages available from Jewel.

“But it is still a good variety for which a lot of testing has occurred, so it’s being made available for those who might want it,” she says.

RU1701084 is a very high-yielding variety but not very different from Diamond, which had just been released.

“Again, it’s a very good variety with lots of data, and it is also being made available to those who might want it,” Moldenauer says.

Some rice breeding lines are advanced right to the brink of release as public varieties, says John Carlin, director of the Arkansas Crop Variety Improvement Program. But like RU1701081 and RU1701084, they are not released because they perform similarly to existing public varieties. They remain in the breeding program where they may offer genomic contributions to other breeding lines but are otherwise shelved.

Some of those lines, however, offer particular advantages for growers in some growing areas.

“We’ve decided to offer some of these breeding lines as commercially released varieties, under exclusive license to a single company, for two reasons,” Carlin says. “They offer growers more options in some parts of the state, and offering them for license helps recoup some of the investment we’ve made in advancing them to this stage of development.”

The division sells its public rice varieties at cost to many seed companies that, in turn, sell them to growers. Carlin says the Division of Agriculture receives no royalties from public varieties.

Renamed under Progeny Ag label

Erwin-Keith Inc. will rename and market the rice seed under the Progeny Ag label, says Nathan Cook, general manager.

“These will be the first rice seed products we sell with our own brand,” he says.

Progeny Ag is the seed brand for Erwin-Keith Inc., Cook says. The company has long offered its own brands of soybeans, corn and wheat. It also sells other brands of rice seed, including U of A public varieties.

Erwin-Keith Inc./Progeny Ag was selected as the distributor for the commercially released varieties based on proposals submitted by several seed companies, Carlin says. The Division of Agriculture’s Foundation Seed Program will produce foundation seed annually for RU1701081 and RU1701084. Erwin-Keith Inc./Progeny Ag will purchase the foundation seed and grow certified seed from it for sale to rice growers.

Recovering development costs

Developing rice varieties — which takes years of crossing, testing and advancing — is costly, Carlin says. Offering some advanced lines as commercial varieties to growers who can use them will help recover some of that cost.

The royalties from the sale of RU1701081 and RU1701084 and other varieties that may be released later will be divided between the Division of Agriculture’s rice breeding and research program and the Arkansas Rice Research and Promotion Board, which helps fund rice breeding and research with rice check-off money.

“Many years ago, the producer community realized the value of research,” says Roger Pohlner, ARRPB chairman. “They initiated the rice check-off program to fund research for better yields and more economical production practices as well as market promotion to enhance the price realized for their crops in the market place.

“The Arkansas Rice Research and Promotion Board administers these check-off funds for both research and promotion. High on the list of priorities for this board is new variety development. The goal is to find higher-yielding varieties that can be produced more economically in an environmentally friendly manner.”

Pohlner says the money the rice board receives from commercially released varieties will go right back into the program.

“The Rice Research and Promotion Board intends to use these proceeds to fund additional research that accomplishes the objectives of the board and meets the needs of rice producers in the state of Arkansas,” he says.

“The additional money from commercial varieties will help us to broaden the breeding and research programs. It will help us to bring more improved varieties into production to help rice farmers sustain both agriculture and profitability.”
