Research Highlights

Rice Varieties

Rice varieties developed at the LSU AgCenter’s H. Rouse Caffey Rice Research Station are grown not only in Louisiana but throughout the southeastern United States. Rice variety development research includes work on long grains, Clearfield long grains, medium grains, Clearfield medium grains, Clearfield specialty types, specialty types with emphasis here on jasmine types. The station in 2017 also released the first variety which will be used with the new Provisia herbicide resistance system.

Clearfield Rice

The technology that has led to the advent of Clearfield rice was derived from research conducted at this LSU AgCenter facility. The technology allows for the control of rice weeds, including weedy (red) rice.

Clearfield rice currently is grown on more than 48 percent of the southern U.S. rice acreage. Most of this acreage is seeded with Clearfield varieties that also were developed at this research station.

Foundation Seed Rice

One of the most important functions of the LSU AgCenter’s H. Rouse Caffey Rice Research Station is the production of foundation rice seed. Foundation seed is the first step in the commercialization of a rice variety.

Puerto Rican Connection
Because of its Puerto Rican connection, the H. Rouse Caffey Rice Research Station breeding program squeezes three growing seasons out of a year, accelerating the process of developing new rice varieties. Without the nursery program at LaJas, Puerto Rico, the breeding program would only be able to grow one generation of rice a year.

Crawfish
The aquaculture research program places emphasis on production practices, forages, and multi-cropping of crawfish with agronomic crops.

Significance of Rice Research

  • Rice varieties developed at the LSU AgCenter’s H. Rouse Caffey Rice Research Station are grown not only in Louisiana but throughout the southeastern United States.
  • Over the past 108 years, the H. Rouse Caffey Rice Research Station has developed 52 varieties that have increased rice yields, quality, disease resistance, and the overall economic viability of the Louisiana and southern U.S. rice industry.
  • Research conducted on agronomic practices at the H. Rouse Caffey Rice Research Station increases production and contributes to the state’s economic development.
  • Production of foundation rice seed developed at the H. Rouse Caffey Rice Research Station provides commercial rice for rice producers.
  • Support of rice and crawfish production provides essential habitat for wildlife species and increases earning potential for rice producers.

2016 Rice Industry Facts

  • More than 2.8 billion pounds of rice produced in Louisiana.
  • 420,820 acres of rice in production in 2016.
  • On average, 6,690 pounds of rice produced per acre.
  • Rice is produced in 31 parishes.
  • Total farm-gate value of rice production was $350 million, and value added to rice production was $102 million in 2016, for a total economic contribution of $470 million.
  • Rice is one of the most durable crops in Louisiana, where hurricanes can be an issue during the growing season.

Future Plans

Rice variety development will continue to be a mainstay of the research program at the LSU AgCenter’s H. Rouse Caffey Rice Research Station. While two research projects focus specifically on variety and hybrid development, most other projects contribute to these efforts through collaborative research. Future variety development will be facilitated through increased use of techniques such as marker-assisted breeding and anther culture.

The H. Rouse Caffey Rice Research Station continues to expand research into the development of rice hybrids. This program is being conducted in cooperation with the Guangxi Academy of Agricultural Sciences in Nanning, China and the Tianjin Academy of Agricultural Science in Tianjin, China. The Puerto Rican nursery will continue to be critical to variety development efforts, and plans are to increase the size of the nursery to accommodate the rice hybrid-development efforts.

Rice diseases, insects, and weeds are major constraints for Louisiana rice production, and research will continue in these three critical areas.

Crawfish production continues to grow in importance in Louisiana, and research will continue to develop new technology to foster this industry.

Research will continue in all rotational crops which are grown in rotation with rice in southwest Louisiana.

The H. Rouse Caffey Rice Research Station conducts an annual field day. The next field day will be on June 28, 2017, and will highlight current breeding, production, disease, and pest research projects.
