Abstract/Contents:Twenty-four bermudagrass (Cynodon spp.) genotypes were evaluated for root growth potential under nonlimiting moisture conditions in the Texas A&M Turfgrass Glasshouse. Rooting depths, total root weights, and shoot weights of 24 bermudagrass (Cynodon) genotypes varied substantially. A duration of 210 days is required to conduct a reliable assessment of genetic rooting potential. Certain Cynodon spp. have a genetic rooting potential of at least 84 inches (2.1m) in depth. The rooting potential of Cynodon spp. is a major contributor to the overall drought resistance mechanism of this species via the dehydration avoidance component. Shoot biomass was not a reliable predictor in selecting deep rooting plants within the Cynodon spp.
