| Rice Variety Selection - An Important First Step/Dermacor X-100 Twenty-five years ago Louisiana was predominantly a medium-grain producing state. In the decade of the 1980s, we planted approximately 65 percent of our acreage in medium-grain varieties, with the reminder seeded to long-grain types. In 2008, Louisiana planted over 95 percent of our acreage in long-grain types. |
| [Image: Released varieties 1991-2011]What’s in a Rice Variety Name? The industry uses the names 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. |
