The LSU AgCenter has approved the release of two new Clearfield lines for the 2010 growing season, according to Dr. Steve Linscombe, LSU AgCenter rice breeder.
The first Clearfield medium-grain (CL261) will be available in the spring for seed and limited commercial production. The line has good yield potential and very good milling and grain quality.
Linscombe said work will continue on more medium-grain Clearfield lines.
"We have some lines in the breeding program that show even greater yield potential," he said.
Linscombe said another line showed higher yields and was near to being released last year, but it was eliminated after it started segregating into populations with varying cereal-chemistry traits.
He said farmers have wanted a Clearfield medium-grain because of the premium paid in 2009 for medium-grain rice. Millers want a Clearfield medium-grain to meet quality demands that include an absence of red rice grains.
A new Clearfield long-grain also will be released for 2010 production and will be designated as CL111. It will have a very early maturity and high yield potential, although not as much as CL151.
It will mature a week earlier than other Clearfield lines – which is desirable for a second crop in south Louisiana. Linscombe said north Louisiana farmers also want early maturity to get their crops out of the fields sooner.
The potential variety has less chalk than CL151 and better blast resistance, according to Linscombe.
