Abstract
The identification and development of turfgrasses with improved salinity tolerance is necessary to maintain adequate turf quality when utilizing nonpotable irrigation water. High salinity can cause salt stress injury resulting in poor turf quality. Therefore, breeders need to develop cultivars with improved salinity tolerance. However, the development of salt tolerant cultivars has been slow due in part to the fact that inheritance of salinity tolerance is complex. Previous screening techniques developed for turfgrasses have included growing plants directly in hydroponic saltwater solutions or some modification including salt solution/sand culture system however, these do not include foliar exposure to irrigation water. The goal of this thesis was to develop novel salinity screening procedures for cool-season turfgrasses to accurately mimic realistic management conditions and screen and evaluate germplasm and cultivars for salinity tolerance. The novel screening methods were compared to standard techniques to determine the feasibility of this screening method for breeding purposes. Inheritance characteristics associated with salinity tolerance will determine the effectiveness of a breeding program in developing new cultivars with increased salinity tolerance. To achieve the objectives, a number of greenhouse and field experiments were designed between the summers of 2005 and 2010. Overhead irrigated salt spray chambers were constructed in the greenhouse and used to evaluate perennial ryegrass clones and Kentucky bluegrass cultivars for salinity tolerance at various salinity concentrations. Cultivars of three cool-season turfgrass species were established in the field and screened for salinity tolerance using overhead irrigation. Using the same field screening procedure, salinity tolerance screening was performed on a number of diverse perennial ryegrass genotypes, as well as parents and progeny from controlled crosses. Significant differences were observed between salinity treatments in the field and greenhouse. Variation in salinity responses ranged from highly tolerant to highly susceptible. The three salinity screening techniques evaluated were highly correlated; however, methods utilizing overhead irrigation resulted in higher salinity stress compared to the hydroponic technique. Inheritance studies indicated that additive gene effects accounted for the majority of the variance associated with salinity tolerance in perennial ryegrass indicating that recurrent selection programs should be effective in developing of salt tolerant cultivars.
