| Abstract/Contents: | "Rises in global climates have brought about droughts that are becoming more frequent and extensive, posing major challenges to both crop productivity and management. As a result, limitations have been imposed on the usage of water for irrigation and have underscored the necessity for incorporating and improving drought-tolerant turfgrasses, such as bermudagrass (Cynodon spp.). Bermudagrass and other warm-season turfgrasses are naturally resistant to drought stress and stand as clear solutions to limiting both irrigation and economic input, especially in the southwestern United States and regions of similar climates. The objective of this research was to evaluate a number of bermudagrass genotypes to capture a range of natural variation in response to drought stress over multiple and extended periods of drought conditions in the field. The genotypes, consisting of 71 hybrids generated at the University of California, Riverside (UCR) and 5 commercially available cultivars, were evaluated under two consecutive dry-down periods where irrigation was withheld then provided for 60 and 14 days respectively. Plots were evaluated at UCR from June through October 2020 for several qualities, including green tissue coverage, dark green color index (DGCI), leaf firing, turf quality, and normalized difference vegetative index (NDVI), then compared with a similar previous study performed at UCR in 2019. Previous studies at UCR have shown multiple genotypes that retained at least 75% green coverage over a 30-day drought period, with preliminary studies suggesting that consecutive dry-down periods may prime genotypes to better respond to subsequent stresses. These findings demonstrate the efficacy of bermudagrass in handling limited water availability and highlight the need for continued efforts to improve upon drought tolerance in bermudagrass breeding programs." |
