DEVELOPMENT OF MEDIUM-GRAIN AND SPECIAL PURPOSE RICE VARIETIES FOR LOUISIANA

OBJECTIVES: To develop superior medium-grain rice varieties with emphasis on the improvement in yield potential, quality (milling, cooking, and processing), disease resistance, lodging resistance, seedling vigor, and early maturity. To develop improved special purpose rice varieties with particular emphasis on high yield potential, superior cooking quality, specialty characteristics, disease and lodging resistance.

APPROACH: The best available germplasm from U.S. breeding programs, the USDA World Collection, and the other sources will be continuously collected, evaluated, and utilized. Characteristics such as high yield potential, superior grain quality, blast and sheath blight resistance, aroma, and kernel elongation will be incorporated into adapted U.S. rice varieties or breeding lines through crossing (single cross, backcrossing, and three-way cross) and molecular marker-assisted selection. Breeding lines with superior yield potential, grain quality (milling, cooking, and processing), disease resistance, and specialty attributes will be evaluated, selected, advanced, and released.

NON-TECHNICAL SUMMARY: Medium-grain type is the second most popular type of rice grown in Louisiana after long-grain type. Even though medium-grain rice acreage has decreased in recent years, an average of 25,000 acres of medium-grain rice was planted in Louisiana from 1998 to 2002. The purposes of this study is to develop superior medium-grain and specialty purpose rice varieties with emphasis on the improvement in yield potential, quality (milling, cooking, and processing), disease resistance, specialty characteristics, lodging resistance, and early maturity.
