Abstract/Contents:"Winter kill in turfgrasses affect the aesthetics and playability of recreational turf areas. Eventually, requiring labor and energy intensive re-establishment procedures to restore the lost area of turf. Bermudagrasses (Cynodon sp) are some of the most important, widely adapted warm-season turfgrasses and are regarded as having excellent tolerance to heat and drought, but low tolerance to freezing temperature. Developing bermudagrasses with better winter survival is the priority of any bermudagrass germplasm improvement program. Therefore, the objective of the study is to evaluate experimental and commercially available putting green bermudagrass genotypes for freeze tolerance by subjecting these to various freezing temperatures (-4 to -14 Ā°C) under controlled environment conditions. The lethal temperature to kill 50% of the population (LT50) for each cultivar was determined. 'Tahoma 31' and 'Champion' were used as the freeze tolerant and freeze susceptible standards, respectively. The freeze tolerance varied among the bermudagrass genotypes. The information gained from this research would help in prescreening genotypes prior to field evaluation. Genotypes with superior freeze tolerance might also help in breeding and development of additional germplasm for testing"
