Abstract: The salinity tolerance of fifty excellent selections and cultivars of warm season turfgrass belonging to five genera and twelve species was determined by leaf firing percentage in hydroponic culture. There were wide variations of salinity tolerance among the fifty selections and cultivars, and the total coefficient of variation (CV) reached 60%. CVs of the genera Zoysia and Cynodon reached 52% and 29%, respectively. Between species, the maximum variation occurred in species of Z. japonica and Z. sinica, where CVs reached 56% and 52%, respectively. Generally, accessions of Z. tenuifolia and Z. matrella had the best salinity tolerance. Paspalum vaginatum ‘Adalayd’, Stenotaphrum secundatum ‘S004’, and some accessions of Z. japonica and Z. sinica were more saline tolerant. Accessions of Cynodon and other accessions of Zoysia were intermediate or low in tolerance. Two accessions of Eremochloa ophiuroides were salt-sensitive. In the genus Zoysia there was better salinity tolerance than in the control cultivars in seven and twelve accessions of ‘Manilagrass’ and ‘Lanyin No. 3’, respectively. Most accessions of Cynodon were more salinity tolerant than the control cultivars (‘Tifgreen’ and ‘Tifdwarf’ ) with the exception of ‘C158’, ‘Nanjing’ bermudagrass and ‘C610’. In total, the most salinity tolerant three selections or cultivars of the fifty accessions were Z. tenuifolia ‘Z160’, Z. matrella ‘Diamond’ and ‘Z075’.
