Salinity tolerance of 20 mashbean genotypes were tested in laboratory under three levels of salinity: 15 mM, 30 mM and 45 mM NaCl, on the basis of their growth behaviour. Out of these two most salt tolerant (VU 1 and KUG 529) and two most salt sensitive (KUG 363 and KUG 539) genotypes were selected for field experiments. Salinity significantly reduced the growth in terms of plant height, leaf area plant−1 and dry matter accumulation in roots, shoots and leaves in all genotypes, though the declension was more pronounced in KUG 363 and KUG 539. Negative effects of salinity on plant growth had an ultimate effect on plant productivity. KUG 529 followed by VU 1 showed high level of tolerance compared to other genotypes.
