Germination of fifteen germplasms of guar (four varieties, BR-2/1, BR-90, BR-99 and BR-2017) and 11 lines (S-5733, S5742, S-5747, S-5759, S-5761, S-5765, S-5784, S-5785, S-5797, S-5798 and S-5825) has been investigated in vitro under NaCl and Na2SO4 salinities (0 to 10 bar) corresponding to 0.203 to 22.20 dS.m-1 in case of NaCl and 0.203 to 23.0 dS.m-1 in case of Na2SO4. Final germination percentage (FGP) was of quite high order reaching ≈ 90 % in several germplasms after four days of incubation in 10 bar NaCl except few germplasms in which germination significantly declined. Sequentially descending order of salt tolerance in terms of increasing per cent reduction of final germination in 10 bar NaCl and Na2SO4 over control was found to be as follows. FGP was generally more affected under Na2SO4.
