Germination parameters and seedling growth of three varieties of boro rice (V1 = BRRI dhan28, V2 = Sylhet Boro and V3 = Bere Ratna) were studied in three concentrations of NaCl {S0 = control (distilled water), S1 = 75 mM NaCl and S2 = 150 mM NaCl}. Germination test was performed following Petri dish method with Completely Randomized Design (CRD) in three replications. Data were collected on germination (%) and shoot and root lengths. There was a wide variation in germination parameters and shoot and root growth among the rice varieties. In all the germination parameters Bere Ratna was found superior, followed by Sylhet Boro. Generally shoot length of the rice varieties gradually decreased with increasing salinity. The highest shoot length (5.53 cm) was found in Sylhet Boro in control. The lowest shoot length (1.30 cm) was found in BRRI dhan28 at 75 mM NaCl. However, root growth was not influenced by salinity. Root and shoot length were negatively related to salt levels.
