| Abstract/Contents: | "Bermudagrass (Cynodon spp.) remains among the most common turfgrasses throughout the southern United States. In recent years, several genotypes have exhibited improved cold tolerance expanding the zone of use for the genus. Additional research has suggested that ultradwarf bermudagrasses (C. dactylon x transvaalensis) exhibit a lower temperature threshold for viability than previously reported. However, winterkill remains a prevalent concern for bermudagrass managers throughout the U.S. transition zone. Furthermore, the genetic stability of the most commonly utilized ultradwarf bermudagrasses continues to be inconsistent. This experiment sought to identify experimental bermudagrass genotypes derived from traditional breeding methods capable of sustaining turf quality when treated with a moderately low mowing regime and managed otherwise as an ultradwarf bermudagrass putting green. Twenty-one genotypes were replicated 4 times in a complete randomized block design. The entries were sprigged in July 2015 with a sand root zone. Entries were allowed to establish through the first year; maintained at 9.5 mm through the summer of 2016 before being reduced to the desired winter height of 4.7 mm in October 2016. In 2017 and 2018, the entries were maintained at 3.4 mm from June through August and 4.7 mm from September through May during the study period. Monthly turf quality parameters were recorded for turf quality, normalized difference vegetative index (NDVI), and digital image analysis. Seasonal data for color, seedhead production, and disease susceptibility were also obtained. Of the 21 entries, 3 commercial standards and 1 experimental genotype demonstrated adequate turf quality parameters under the putting green management regime in 2017; in 2018, only the commercial standards demonstrated turf quality adequate for use as a putting green turf." |
