A New Trio Hits The Field

LSU AgCenter announces three new rice varieties

The Louisiana Rice Research Board members were told on Nov. 16 that farmers will have three new varieties of rice, developed by the LSU AgCenter, to consider for planting in the 2011 season. The varieties are the result of rice breeding work funded in part by the Louisiana Rice Research Board through checkoff funds originating from a 5-cent charge paid into a research fund on every 100 pounds of rice sold by farmers.

The board met to decide how to spend those funds for the coming year, agreeing to allocate more than $1.4 million for 20 projects, including economic research, agronomy, disease and insect treatments and variety development.

The new varieties announced by Steve Linscombe, LSU AgCenter rice breeder and director of the Rice Research Station, include a new medium grain variety, a long-grain Clearfield variety and an aromatic Jasmine-type variety. Seed from the three releases will provide limited seed production in 2011.

‘Caffey’ Variety Honors Retired Chancellor
The medium grain variety has been named Caffey, to recognize the work of Rouse Caffey, retired LSU AgCenter chancellor who had been a director of the Rice Research Station.

 
More About Roy J – An Arkansas Release
 

In the Spring of 2010, the University of Arkansas Division of Agriculture released a high-yielding, long-grain rice variety, “Roy J,” which is named in honor of the late Roy J. Smith, who was a weed scientist with the USDA Agricultural Research Service based at the Rice Research and Extension Center (RREC) for many years.

Following is more information about this new Arkansas release.

• Lodging resistance better than that of Wells

• Excellent rough rice yields with good milling yields (2007-2009 mean 192 bu/A compared to Wells, Francis and Taggart at 176, 180 and 180 bu/A, respectively; 3-year data for milling yield head rice: Total rice is 57:70 for RU0801076 compared to Wells, Francis Taggart and Cybonnet at 56:72, 59:70, 54:71 and 62:72).

• Maturity is about one day later in maturity than Drew, or two days later in maturity than LaGrue

• Plant height between Wells and LaGrue is about two inches taller than Wells and two inches shorter than LaGrue

• Grain weight and size is similar to Wells

• N fertilizer requirements: 135 lbs/A

• Blast: susceptible in Arkansas conditions similar to Wells

• Sheath blight: Moderately susceptible, similar to Drew, Wells, Francis or LaGrue

• Bacterial panicle blight susceptible, similar to Wells/Francis

• Kernel smut susceptible like Wells

• Straight head: Susceptible similar to Jupiter

• Typical Southern U.S. long-grain cooking quality

Linscombe said this medium grain variety has consistently out-yielded Neptune and Jupiter varieties in testing for the past three years. Its grain is bolder and similar to Calrose, a quality preferred by many end users.

Caffey was director of the Rice Research Station from 1962 until 1970. Previously, he had started a rice research facility in Mississippi. He began his rice work as a student in 1955, so a variety named for him is deeply rewarding.

“I feel very honored, and it’s very satisfying,” says Caffey. “I’ve had a long association with rice, and I still maintain my interest in the rice industry.”

Linscombe said Caffey’s work in rice research paved the way for the LSU AgCenter to have one of the top research facilities of its kind. “Dr. Caffey had the foresight to advance the research at the station, and naming a variety for him is a way of thanking him for those efforts,” he says.

CL152 & Jazzman II Enter The Market
The new Clearfield variety has been designated CL152. Its grain quality is superior to CL151, and it has more resistance to lodging – or falling over – and to straighthead and blast diseases, according to Linscombe, who developed this variety.

The new aromatic variety has been named Jazzman II. It has increased aroma compared with its predecessor Jazzman, which was released last year to compete with imports of Jasmine rice from Thailand, according to Xueyan Sha, the LSU AgCenter rice breeder responsible for both versions of Jazzman.
