Abstract/Contents: | "Bermudagrasses, Cynodon spp., periodically experience freeze damage when grown in the transition zone for warm and cool-season turfgrasses. Therefore, there is a need to develop and characterize bermudagrass cultivars with superior freeze tolerance, as well as other turf quality characteristics. Our objective was to determine relative freeze tolerance levels of recently released cultivars, advanced lines, and standard cultivars from the 2002 National Turfgrass Evaluation Program bermudagrass trials using laboratory based methodology. Experiments were divided into vegetatively-propagated and seed-propagated cultivars. Twenty-seven seed-propagated cultivars were randomly divided into five groups with 'Arizona Common' serving as a standard in each of the five groups. 'Tifway' was used as a standard cultivar for the three vegetatively-propagated groups, facilitating comparisons of relative tolerance across groups. A range in freeze tolerance from 22.5° F (-5.3° C) to 16.3° F (-8.7° C) was observed for seed-propagated cultivars. Most seed-propagated cultivars had a freeze tolerance level similar to 'Arizona Common' (21.2° F), but four were significantly more freeze tolerant. Freeze tolerance of vegetatively-propagated cultivars ranged from 20.8° F (-6.2°C) to 11.3° F ( -11.5° C). While three cultivars were significantly less hardy than 'Tifway', four bermudagrasses exhibited significantly greater freeze tolerance, reflecting the potential to survive in the northern boundary of the transition zone with a lower probability of winterkill. Our research findings include: The most freeze tolerant seed-propagated cultivars were 'CIS-CD6', 'Riviera', 'Transcontinental', and 'SWI-1014'. 'OKC 70-18', 'Ashmore', 'Patriot', and 'Midlawn' were the most freeze tolerant vegetatively-propagated cultivars. 'GN-1', 'Celebration', and 'MS-Choice' were significantly less freeze tolerant than 'Tifway'." |
