Salinity is a complex abiotic stress that affects physiology and biochemistry of plants and significantly reduces both crop yield and quality. Considering the global increase in soil salinity, it is required to develop salt-tolerant cultivars for various crops. Solanum lycopersicum L. is an important Solanaceous crop with a diverse level of genotype dependent salt tolerance. However, the evaluation of salt tolerance in tomato genotypes or screening for traits utilized reliably for breeding against salt tolerance is scarcely reported. Thirteen different genotypes of tomato were exposed to salinity with three simulated soil NaCl levels (0, 75 and 150 mM) in a complete randomized design with three pots per treatment. Morpho-physiological traits (fresh and dry weight of shoot and roots, chlorophyll content, Na⁺ accumulation, K⁺ content, Na⁺/K⁺ ratio, proline content and percent ion leakage) were measured to determine the extent of salt tolerance. Different genotypes, salinity levels and their interaction significantly influenced both the observed morphological and physiological traits of tomato. Fresh weight of shoot and root, dry weight of root and shoot, chlorophyll content, K⁺ content and proline content were significantly increased by Rio Grande genotype, while higher Na⁺ content and percent ion leakage was observed in Early King genotype. Among all tested genotypes, Rio Grande and Red Star were found salt tolerant and Early King and Vigo were found the most susceptible tomato genotypes.

盐度是一种复杂的非生物胁迫，会影响植物的生理和生物化学，并显着降低作物产量和质量。考虑到全球土壤盐分的增加，需要为各种作物开发耐盐栽培品种。Solanum lycopersicum  L. 是一种重要的茄科作物，具有不同程度的基因型依赖性耐盐性。然而，关于番茄基因型的耐盐性评估或筛选可用于抗盐育种的可靠性状的报道很少。将 13 种不同基因型的番茄暴露于盐分，三种模拟土壤 NaCl 水平（0、75 和 150 mM）采用完全随机设计，每次处理三个盆。形态生理性状（芽和根的鲜重和干重、叶绿素含量、Na⁺积累、K ⁺含量、Na ⁺ /K ⁺比值、脯氨酸含量和离子泄漏百分比）以确定耐盐程度。不同的基因型、盐度水平及其相互作用显着影响观察到的番茄形态和生理特征。Rio Grande 基因型显着增加了地上部和根的鲜重、根和地上部的干重、叶绿素含量、K ⁺含量和脯氨酸含量，而在 Early King 基因型中观察到更高的 Na ⁺含量和离子泄漏百分比。在所有测试的基因型中，Rio Grande 和 Red Star 被发现耐盐，而 Early King 和 Vigo 是最易感的番茄基因型。
