| Abstract/Contents: | "Limited water availability has resorted many communities to impose watering restrictions on turfgrass. Watering restrictions become more stringent as the level of drought increases. A high priority in turfgrass breeding programs is to develop water-saving varieties with improved turf quality. An understanding of genotype by environment interaction (G×E) is necessary to develop cultivars with broad adaptation. In this project, we imposed a stage 5 irrigation restriction (no irrigation after establishment) and evaluated turf quality in 153 entries of four turfgrass species (43 zoysiagrass, 44 bermudagrass, 44 St. Augustine grass, and 22 seashore paspalum). Multi-location trials were established following a randomized complete block design with 3 replications in Florida, North Carolina, Oklahoma, and Texas that represent different climatic zones and soil types. Variance components and genetic parameters were calculated using linear mixed models in ASReml-R. Heritabilities for turf quality among the four species varied from site to site ranging from 0.00 to 0.43 with an overall heritability of 0.27. Bermudagrass showed relatively higher heritabilities for turf quality at all locations implying that turf quality could be improved by selection and breeding." |
