Goals / Objectives
To develop superior conventional and Clearfield varieties for Louisiana and Gulf South production with emphasis on improvements in yield, quality (milling yield, cooking quality, and processing adaptability), disease resistance, seedling vigor, earliness, ratoon potential, lodging resistance, environmental stability, and herbicide and insect tolerance. To develop non-conventional rice varieties incorporating traits such as herbicide resistance, insect resistance, disease resistance, quality characteristics, and other important traits through mutation breeding. To conduct research on agronomy, production, and management of rice as relates to increased economic return from new varieties and breeding lines. To produce additional generations of advancement and selection of rice breeding lines per year and increase seed of promising selections to facilitate the release of new varieties by the use of the Puerto Rico winter nursery.
Project Methods
Develop new genetic populations in all commercial classes of rice by artificial hybridization and mutagenesis. Advance these populations while selecting for desirable characteristics. Evaluate advanced selections in replicated tests over years and locations to identify superior lines. Increase superior lines through the Rice Research Station Foundation Seed Program. Conduct concurrent studies related to varietal improvement.

Target Audience: Targeted audiences include rice producers, rice processors, rice end-users, rice consultants, other scientists and the general public. Changes/Problems: An important aspect of rice variety development is evaluation of cereal chemistry components of the grain (primarily amylose content and gelatinization temperature) of experimental lines. Historically, this has been done by another research center as a service for this project. Turnaround time and accuracy have become a problem in this area. For this reason, the project is in the process of purchasing analytical instruments and developing expertise in analyzing samples for these characteristics to alleviate these issues. What opportunities for training and professional development has the project provided? The project has provided opportunities for training and professional development by making presentations at numerous field days, grower meetings, and national and international rice meetings. Presentations were made at seven Louisiana rice grower parish or regional meetings, five parish or regional field days, three national meetings (invited), andfour international meetings (invited). Consulting was provided to numerous rice producers and consultants via phone calls, emails and field visits. Three winter nurseries were planted and successfully harvested at the Puerto Rico facility. The project leader also provides a significant amount of service to the U.S. rice industry by serving on a number of committees of state andnational rice organizations. How have the results been disseminated to communities of interest? Results have been disseminated to producers, scientists, extension professionals, and agribusinesses through refereed journal articles, annual reports, newsletters, oral presentations, field days, and one-on-one communication. What do you plan to do during the next reporting period to accomplish the goals? This is a long-term project in variety development and will continue all aspects ofRice Breeding and Genetic Research to accomplish goals listed -- To develop superior conventional and Clearfield varieties for Louisiana and Gulf South production with emphasis on improvements in yield, quality (milling yield, cooking quality, and processing adaptability), disease resistance, seedling vigor, earliness, ratoon potential, lodging resistance, environmental stability, and herbicide and insect tolerance. To develop non-conventional rice varieties incorporating traits such as herbicide resistance, insect resistance, disease resistance, quality characteristics, and other important traits through mutation breeding. To conduct research on agronomy, production, and management of rice as relates to increased economic return from new varieties and breeding lines. To produce additional generations of advancement and selection of rice breeding lines per year and increase seed of promising selections to facilitate the release of new varieties by the use of the Puerto Rico winter nursery.

Impacts
What was accomplished under these goals? Rice variety development included 249 new crosses, evaluation and selection in 235 F2 populations, and selection in over 76,000 progeny rows. The Uniform Regional Rice Nursery evaluation was conducted in cooperation with other southern U.S. public rice breeding programs. Yield, milling and agronomic performance of 60 advanced experimental lines and released varieties was conducted at the Rice Research Station as well as at seven off-station locations throughoutLouisiana rice growing regions. Preliminary testing included 750 lines at the Rice Research Station. Two advanced experimental rice lines were identified as candidates for releases and increased as foundation seed. LA2065 is a Clearfield medium grain with excellent yield, good grain appearance, very good milling quality and excellent resistance to blast disease. LA2025 is a Jazzman Clearfield long grain with very good yield, good grain quality and excellent aroma. This project has identified a large number of advanced experimental rice lines that show good potential as future new rice varieties. These lines will be entered into additional testing to provide additional information on their potential.

Progress 01/01/12 to 12/31/12

Outputs
OUTPUTS: An advanced Clearfield medium grain, an advanced Clearfield long grain and an advanced Clearfield jasmine long grain were increased to provide breeder seed for a foundation seed production of these three lines in 2013. Three winter nurseries were planted and harvested at the Puerto Rico facility. This project generated 14 outputs in the form of 10 presentations at Louisiana grower meetings/field days, two at Arkansas grower meetings, and two presentations at national grower meetings. Six other outputs in the form of regional field day presentations were also delivered. Five newsletter articles, 12 popular press articles, 1 book chapter and 2 referred journal articles were published in 2012. PARTICIPANTS: Steve Linscombe, (PI); X. Sha, J. Oard, K. Bearb, B. Theunissen, R. Zaunbrecher, H. Hoffpauir, and Brandon Frey, LSU AgCenter. TARGET AUDIENCES: Target audiences for this project include crop producers, consultants, and agronomy professionals. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
Rice variety development activities included over 360 crosses, 400 F2 populations and over 97,000 progeny rows for selection or purification. Yield, milling and agronomic performance trials were conducted at the Rice Research Station, as well as at six off-station locations throughout the rice growing regions of Louisiana. These studies included 60 released varieties and advanced experimental lines. Preliminary testing included over 600 entries. A date of planting study (eight planting dates) was conducted to evaluate the effect of planting dates on yield, quality and agronomic performance of 12 varieties or experimental lines. Two planting dates were included for a rice quality study.
