Assessment of Tomato Accessions for Various Seedling Attributes Under NaClSalt Stress

In this study, the performance of twenty tomato genotypes was evaluated against two different NaCl concentrations (6 and 12 dSm -1 ) along with a control in a glasshouse of the Faculty of Agriculture, University of Agriculture Faisalabad, Pakistan.The experiment was conducted under a completely randomized design (CRD) with three replications.The morphological characteristics such as plant height, root length, shoot length, fresh root weight, fresh shoot weight, dry root weight, dry shoot weight, fresh plant biomass, dry plant biomass, fresh root to shoot weight ratio, dry root to shoot weight ratio, root/shoot length ratio, Na + determination of roots and leaves, K + determination of roots and leaves, and Na + /K + ratio of roots and leaves were recorded.Analysis of variance (ANOVA) was performed to estimate the variability among the tomato genotypes.The results showed that genotype CLN-2498A performed the best for all the studied traits under control conditions, while genotype Nadir performed poorly for these parameters.Genotype PGRI-17902 was considered as the best genotype for all traits under NaCl stress of 6 dSm -1 , while genotype PGRI-19905 performed poorly.Under the 12 dSm -1 stress condition, PGRI-17260 appeared to be the best genotype for all recorded traits, and Sundar revealed the least performance for all the above-mentioned characters.The outcomes of this study could be helpful in developing salt-tolerant tomato cultivars.
