Abstract
Abstract The tomato (Solanum lycopersicum L.) is an annual vegetable cultivated all over the world. It faces biotic and abiotic stresses, such as salinity, in arid and semiarid regions. Investigating the relationship between physiological and economic traits, such as fruit yield, under stress conditions is necessary to identify tolerant genotypes. This study was conducted to identify tolerant tomato families according to the relationship between several important physiological, morphological and phenological traits. Twenty S3 families were cultivated in a factorial experiment (factor1: families and factor2: normal conditions and salinity stress) based on a randomized complete block design with three replications in 2019. Twenty physiological, agronomic and fruit-quality-related traits were investigated. Analysis of variance was used to prove the existing effective genetic diversity. Genetic diversity and the relationships between traits were graphically shown using heatmap clustering. Finally, genetic parameters, such as Pearson’s correlation, trait stability index and heritability were used to calculate the mathematical value of families using the Modified Analytical Hierarchy Process. Families exhibited different behaviours under normal and stress conditions. The tolerant families responded physiologically to the salt stress. Therefore, they reduced both cell membrane degradation and photosynthesis disruption by increasing proline, lycopene, carotenoid and sugar content. Therefore, fewer reductions in morphological traits were observed in these families. The most important traits based on the selection strategy were lycopene content, K+/Na+ ratio, days to flowering and biological yield. In addition, three families, H4/T/30/1, H1/T/12/5 and H1/T/47/4, were selected as the most suitable alternatives to construct the breeding population of the next generation.
