| Abstract/Contents: | "Changes in global climates are a growing cause of concern with obvious negative impacts on crops, especially in regards to the availability of water. As climates experience warmer trends, it is becoming increasingly more important to manage the consumption of available water resources, further highlighting the urgency in improving drought tolerant crops, such as warm-season turfgrasses like bermudagrass (Cynodon spp.). There is a growing demand for new cultivars of bermudagrass that would require less water, especially throughout the Southwest region of the United States and among golf courses. The objective of this research was to evaluate 76 bermudagrass entries, consisting of 71 hybrids developed at University of California, Riverside (UCR) and 5 commercial cultivars, for drought tolerance. Low precipitation during the summer season in Southern California allows for the simulation of drought conditions, and preliminary studies conducted at UCR showed substantial differences among bermudagrass accessions and commercial cultivars in response to drought. All 76 entries were planted from 2.5-inch plugs in replicates of 3 in Riverside, CA on May 8, 2019. Irrigation was subsequently turned off on August 1, 2019, marking the start of the dry-down study. Drought tolerance was initially evaluated twice with visual ratings on genetic color, then biweekly for percentage of the plant's green cover (LC), scalping, and normalized difference vegetation index (NDVI). Almost 75% of evaluated plots retained at least 85% LC at the 24 day mark, highlighting the potential for generating drought tolerant hybrids that may compete at or above the current commercial standard, Celebration." |
