Abstract/Contents:"Water limitations are currently one of the biggest challenges to the turfgrass industry. Thus, improving drought resistance of turfgrass is a critical goal for breeding programs across the southern US. The objective of this study was to evaluate the performance under drought of bermudagrass (Cynodon Rich. species), St. Augustinegrass (Stenotaphrum secundatum (Walter) Kuntze), seashore paspalum (Paspalum vaginatum Swartz) and zoysiagrass (Zoysia Willd. species) breeding lines from the breeding programs at Oklahoma State University, University of Georgia, North Carolina State University, Texas A&M University and University of Florida. Field trials arranged as randomized complete-block designs with three replications were conducted at research facilities at Citra (Florida) and Dallas (Texas) from 2016 to 2018. The response variables evaluated were percent living ground cover (%GC) and turfgrass quality (TQ, NTEP ratings from 1 to 9) under drought conditions (TQD), and turfgrass quality under normal or non-drought conditions (TQND). The genetic variance was significant for TQND and TQD in bermudagrass, TQD in St. Augustinegrass, and all traits in zoysiagrass. The heritability estimates ranged from null to moderate for %GC and TQND, whereas they ranged from null to high for TQD. The type-A correlation between TQD and TQND was 1 for all species in the multi-environment analysis, except for St. Augustinegrass (0.89). There were genotypes that performed better than the checks for TQND and TQD for all species, except for S. paspalum. In conclusion, there was genetic variability for TQD in bermudagrasses, zoysiagrasses, and St. Augustinegrass, and indirect selection can be effective to select drought resistant genotypes."
