of the project, researchers will be evaluating the endophyte population for the 50 commercially available perennial ryegrass cultivars in the study. Tiller field samples will be collected for each plot for endophyte analysis. Establishment, monthly color, monthly quality, and traffic tolerance will be compared to endophyte presence and type for this study.
In the fall of 2023, endophyte exploration will occur in the 2018 NTEP Tall Fescue trials located in Corvallis, OR, which includes 42 commercially available cultivars. Tiller field samples will be collected for each plot for endophyte analysis. Establishment, monthly color, monthly quality, and cold tolerance will be compared to endophyte presence and type for this study. Polymerase Chain Reaction (PCR) will be used for evaluation of endophyte status and type.
