Abstract/Contents:"Centipedegrass [Eremochloa ophiuroides (Munro) Hack.] is a warm-season turfgrass grown in the southern United States. It requires few inputs and is more tolerant to pests than most warm-season turfgrass species. Because of this, centipede is popular among homeowners in the transition zone. However, further improvements on its aesthetic value would increase the species marketability. A centipedegrass breeding program was established at NC State University in 2010 to improve turf quality in combination with abiotic stress tolerance. A set of 22 breeding lines were selected from those efforts, but prior to identifying candidates for commercial release, their optimal mode of production needs to be elucidated. In 2022, a study was conducted to evaluate the best 15 breeding lines and four controls (Tifblair, Santee, Covington and Common) for their establishment speed when planted with seeds (rate = 0.23 Kg/93 m2) versus sprigs (rate = 0.09 m2 sod/0.84 m2). Entries were established in 1.4 x 1.4 m plots at three locations in North Carolina: Quality Turf Farm (Burgaw), McKilwean Turf Farms (New Bern) and Lake Wheeler Turfgrass Field Laboratory (Raleigh). Visual and digital data on percent green cover was collected monthly during the growing season. Additionally, turf quality traits were evaluated at the peak of season according to NTEP (1-9 scale). Results indicated that while seeding initially reaches a higher percent green cover, sprigging is able to catch up under the right conditions and is a valid method for establishment of centipedegrass. Several breeding lines outperformed the checks across establishment methods and locations and in terms of establishment speed. Within methods, breeding lines CEN15453 and CEN15827 were the most promising entries for seeding and sprigging, respectively. Breeding line CEN15827 was the top performer across locations and establishment methods, indicating it might be the most versatile and has good potential for commercial release."
