Abstract: Salinity tolerance levels of forty-three local melon genotypes collected from Lake Van Basin were evaluated based on their seedling performances on two different salinity levels compared with the control. Seven vegetative characteristics of seedlings were measured besides some of their mineral matter contents. For the final salinity tolerance determination, the death rate, the leaf area, the dry matter content of the shoots, the Na content and the rates of K:Na and Na:Ca were employed. While the genotypes 65 EDR 03, 65 MER 01, 65 ER 14, 65 ERC 12 and 65 ERC 09 were found to be the most tolerant ones to salinity, the genotypes 65 ER 04, 65 EDR 01, 65 ERC 03, 65 ERC 16 and 13 TAT 03 were found to be the least tolerant ones to salinity.
