Registration of ‘Catahoula’ Rice

Abstract

‘Catahoula’ (Reg. No. CV‐130, PI 654462), a conventional long‐grain rice (Oryza sativa L.) cultivar, was developed by the Louisiana State University Agricultural Center at the Rice Research Station near Crowley, LA, and approved for release by the director of the Louisiana Agricultural Experiment Station in 2007. The population from which Catahoula was derived began as a single cross of RU9502008‐A/‘Drew’ that was made in 1997 at the Rice Research Station. The long‐grain female RU9502008‐A, a sister line to ‘Cocodrie’ first tested in the Uniform Regional Rice Nursery in 1995, is a high‐yielding, widely adapted, semidwarf experimental line. Drew is noted for its resistance to most major races of blast disease, caused by the fungus Pyricularia grisea (Cooke) Sacc. Catahoula originated as a selected F2:4 line in 2001. Subsequent testing in preliminary yield trials in 2002 indicated high yield and quality potential and favorable agronomic characteristics. From 2003 to 2007, Catahoula was tested in statewide and multistate yield and performance trials as RU0302082. Catahoula is a high‐yielding, blast‐resistant, semidwarf cultivar with good milling quality, excellent lodging resistance, and grain quality parameters within the U.S. long‐grain market classification.
