The study was conducted to investigate the effect of salinity levels on seed germination and seedling characteristics of sorghum (Sorghm bicolor L.) cultivars. A laboratory experiment was conducted using new sorghum phenotype Barbarei (Abu-ragaba and Abu-kungara) cultivars in comparison with other two locally improved varieties (Tabat and Wad-Ahmad). Fifty seeds of each of the cultivars were germinated in Petri dishes containing filter paper of 9 cm diameter. Treatments comprised of control (distilled water), 0.5%, 1.0% and 1.5% Sodium Chloride (NaCl) were laid in a factorial experiment in completely randomized design (CRD) with 4 replications. Data recorded was subjected to analysis of variance (ANOVA). Least Significant Differences (LSD) method was used to test the differences between treatment means at 5% and 1% probability level. Number of germinated seeds was significantly affected by salinity level, especially by the higher salt concentrations compared to the control. Germination percentage and seedling vigor index (SVI) were decreased with increasing salinity level. The differences between treatments were highly significant (p ≤ 0.01). The highest seed germination percentage (97.5%) and seedling vigor index (3.79) were found with the control (0% NaCl) and the lowest values were found with 1.5% concentration. Plumule length and radical length decreased significantly as concentration of NaCl increased. Results indicated that cultivar had a highly significant effect (p ≤ 0.01) on the parameters measured. Results indicated that Barbarei cultivars were found to be sensitive to salinity when compared to Tabat and Wad-Ahmed, Tabat seems to be more salt tolerant cultivar. The interaction of salinity level × cultivar exerted significant effect (p ≤ 0.05) on pumule length, radical length and final germination percentage.
