Globally, m aize is an important cereal crop and is used a s staple food in many countries . Salinity is a wide spreading problem of the world; it is inevitable now to develop the verities which can produce well in salt effected soils. Present study was planned to visualize the response s (shoot length, root length, shoot fresh weight, root fresh weight, Na+ and K+) of genetically distant maize accessions at variable salinity levels (Control, 5 dS m-1, 10 dSm-1 and 15 dS m-1). Experiment was conducted in solution culture following completely randomized design (CRD). Maximum growth in all aspects was observed at lowest level of salinity stress. Growth decreased in all the genotypes with the increase of salinity level. Analysis was performed in R -Software; all the treatments show ed significant differences in all the evaluating standards. Analysis of variance was further divided into linear, quadratic and cubic contrasts. Best performing accessions could be used in future breeding programs with focus to develop salinity tolerant maize varieties.
