Abstract: The aim of these experiments was to determine the differences in salt resistance among Cynodon dactylon germplasm collected from Xinjiang. The relative germination rate, relative germination energy, germination index, and the length of the radical and plumule of 50 C. dactylon accessions were measured with the paper germination method under 0 (control), 0.4%, 0.8%, 1.2%, and 1.6% NaCl stress. Then, a synthetic evaluation of salt-resistance was conducted using the cluster analysis method. As the salt concentration increased, the relative germination rate, relative germination energy, and germination index of C. dactylon significantly decreased, and the length of the radical and plumule first increased then decreased, and peaked at 0.4% NaCl. As the salt concentration increased, the variation coefficient of all indexes increased. The variation coefficient under 1.6% salt stress was more than 2.0 times that in the control (no NaCl). The semi-lethal NaCl concentration for the C. dactylon germplasm was 1.28% (variation coefficient, 45.66%) and 1.2% NaCl was the optimum concentration to evaluate the salt tolerance of C. dactylon. The comprehensive cluster analysis of 50 Xinjiang C. dactylon accessions identified Cd012 as the most salt-tolerant accession; Cd019, Cd021, Cd020, and Cd054 as moderately salt-tolerant accessions; and Cd001, Cd033, Cd035, Cd057, and Cd059 as salt-sensitive accessions.
