Even more high-protein rice scheduled for 2013 testing

Dr. Ida Wenefrida will plant a total 25 lines of high-protein rice in 2013 – conducting a range of preliminary yield tests and multilocation tests of the rice varieties.

Wenefrida also said seven high-protein lines were grown as part of a multilocation test conducted during 2012 in Vermilion, Jefferson Davis, Acadia and Evangeline parishes. In those tests, she said, the rice showed a consistent protein level of up to 13 percent, with yields similar to their original cultivars.

"We don’t look at anything with more than 13 percent," Wenefrida said. "We have found that any lines with protein exceeding 13 percent result in a large number of sterile panicles."

Ordinary rice has a protein level around 7 percent. Wenefrida said multilocation testing will be done for two more years in Louisiana before selecting lines for a uniform regional nursery test that will distribute the rice so it can be grown on research plots in Texas, Mississippi, Arkansas, Missouri and California.

The LSU AgCenter scientist said lab testing is being done on the milling quality and cereal chemistry of the tested lines to make sure grain quality, as well as gel temperature and amylose content, are satisfactory.
