The PDF to the right is a book that contains the released rice varieties of the LSU AgCenter H. Rouse Caffey Rice Research Station for the years 1917-2015.

The industry uses the name to designate varieties throughout the time they are produced and often well beyond their commercial production. The variety name is important because multiple facets of the seed industry are based on the name. These include seed certification and seed sales and delivery. When rice farmers book seed for the upcoming planting season, they book by weight volume of a specific certification class of a specific variety name. Many cultural management decisions are variety-specific, and these recommendations are typically based on research conducted by numerous AgCenter scientists while the variety is in development prior to its release. These management decisions can include seeding rate and depth, nitrogen fertilization rates and timings, and herbicide and fungicide choices, as well as deciding which field to harvest first. The latter is based on the fact that some varieties can stay in the field longer than others without significant quality reductions. In addition, the variety name is crucial once a shipment of rice reaches the mill. While in some cases different varieties can be co-mingled, in other cases they cannot. This is certainly true with aromatic specialty varieties.

We are often asked how variety names are derived. The LSU AgCenter has a formal procedure for release of a new variety. When a breeder decides that an experimental line warrants consideration for release, a request is made to the director of the Louisiana Agricultural Experiment Station. This request includes a data summary comparing the potential new variety with those currently being grown. The director then appoints a committee of experiment station scientists to evaluate the data and make a recommendation to the director, who then makes the final decision. If that decision is positive, the breeder is asked to recommend a name for the new variety, and again, the director has final approval.
