Abstract/Contents:"Current and predicted urban water-supply shortfalls mandate water conservation, including the increased use of low-maintenance turf. This study was conducted to evaluate the genetic variation of a rhizomatous crested wheatgrass population for low maintenance turf use. CWG-R is an experimental population of crested wheatgrass from Iran. In comparison to RoadCrest, this population has coarser leaves, but under no irrigation, stays green longer into the summer. Ninety selected CWG-R clonal lines were established in 1998 as space-plant plots in an RCB design. Plots were irrigated weekly at 50% ET and fertilized twice a year with 1 lb. N per 1000 ft2. Plants were mowed to 9 cm as needed, such that only one-third of plant height was removed. Data including turf quality, color, regrowth, and rhizomatous spread, were collected throughout the growing season. Special consideration was given to critical limiting factors in the CWG-R population, including regrowth in the spring, turf quality and color in July, and spread in the fall. The analysis of 1999 data indicated there was significant genetic variation between clonal lines with broad-sense heritabilities of 0.78, 0.92, 0.69, and 0.87, for regrowth (May), turf quality (July), color (July), and spread (Aug.), respectively. Additional results including year 2000 data will be presented."
