Abstract

Sea oats (Uniola paniculata L.) is a perennial grass native to the Gulf of Mexico and Atlantic coasts that is commonly used to stabilize beaches. Three sea oats cultivars with excellent plant vigor, plant spread, and enhanced stem counts before and after major hurricanes were developed from seeds collected from natural growing areas of the United States: 'LA12- 201' (Reg. No. CV-265, PI 665050), 'LA12-202' (Reg. No. CV-266, PI 665051), and 'LA12-203' (Reg. No. CV-267, PI 665052). LA12-201, LA12-202, and LA12-203 are clonal cultivars that were tested in unreplicated and replicated field trials for 3 yr and compared with 'Caminada', an ecotype adapted to the north-central coast of the Gulf of Mexico that is used extensively for beach restoration in Louisiana. LA12-201 and LA12-202 were as vigorous, dense, and tall as Caminada before and after a major hurricane, except on one evaluation date when both were denser and taller than Caminada. LA12-203 was as vigorous, dense, and tall as Caminada on all evaluation dates. Amplified Fragment Length Polymorphism (AFLP) analysis of LA12-201, LA12-202, LA12-203, and Caminada indicated that the three sea oats cultivars are genetically distinct. Due to their proven performance before and after major hurricanes, LA12-201, LA12-202, and LA12-203 are recommended for beach restoration projects in the northern Gulf of Mexico coast. © Crop Science Society of America.
