University of Arkansas System Division of Agriculture researchers have developed a new rice variety designed to produce higher yields than existing varieties. The new variety, dubbed CLL16, is a long-grain Clearfield rice that is expected to be available in 2021 from Horizon Ag.
CLL16 averages approximately 205 bushels per acre, according to Karen Moldenhauer, professor and rice breeder for the Division of Agriculture’s Arkansas Agricultural Experiment Station. By contrast, Diamond rice variety yields 204 bushels per acre on average.
In addition, the new rice variety reportedly provides strong milling yields. On average, the variety provides 63 percent whole kernel and 69 percent total milled rice during Arkansas Rice Performance Trials throughout Arkansas.
Moldenhauercompared it to the existing Diamond variety, noting that CLL16 has a standard height with a 36-inch canopy. The new variety also compares to other varieties like CL172 and Wells in regard to its early maturity date. It averages approximately 86 days to 50 percent heading.
“Grain weight and size are similar to Diamond with nice long, plump kernels. It has typical southern U.S. long-grain cooking quality,” she says. “The plants have very strong straw, indicating good lodging resistance.”
Originally developed at Louisiana State University, Clearfield rice was developed to be tolerant to imidazoline-based herbicides, according to Bob Scott, Rice Research and Extension Center director.The breeding material for the rice lines were later shared with the Division of Agriculture by BASF. Horizon Ag is licensed by BASF to market Clearfield rice.
“Horizon Ag is excited to market CLL16, developed in partnership with the University of Arkansas System Division of Agriculture and BASF,” Dr. Tim Walker, Horizon Ag general manager, said in a statement. “This variety promises a step change in yield potential, while offering industry leading blast tolerance and a milled product that continues to bring back the Gold Standard rice the Southern USA has historically produced.”
