 The study aimed to identify the response of melanoccessions and cultivars to salt stress using mixture modeling, which revealed heterogeneity in the dataset. The seedlings of 13 melanogenotypes were harvested two weeks after salt application and nutrient contents, enzyme activities, lipid peroxidation, and photosynthetic pigment contents were measured. Mixture modeling and correlation analysis were used to evaluate the experimental datasets, revealing differences in responses to salt application among genotypes. The YYU-11 and YYU-4 genotypes were found to be the most tolerant to salt stress based on their smallest decreases in K, NaRatios. Enzyme activity decreased in response to salt application with the YYU-29 genotype exhibiting the highest K, NaRatio, and the smallest change in MDA content under salt stress.
