turfgrass performance is reviewed for a transition zone in the eastern United States where neither warm-season or cool-season turfgrasses give satisfactory performance. Kentucky bluegrass, Poa pratensis L., is widely grown in this area but cultivars now available are not sufficiently tolerant to summer temperature and drought stresses even with careful management. Characteristics of Kentucky bluegrass strains that may be important to their performance under high temperature stress are reviewed. A breeding approach for improvement of the species is suggested and progress to date is reported.
