Assessment of salinity tolerance in onion (<i>Allium cepa</i> L.) genotypes at germination stage through morphological traits and multivariate analysis.

ABSTRACT: Salinity is a major abiotic stress that affects crop growth and development, particularly in crops like onions (Allium cepa L.), which are sensitive to saline conditions. Salinity stress limits crop productivity and is difficult to simulate on farms, hindering parental selection for hybridization programs and the development of tolerant cultivars. In this study, 116 A. cepa genotypes and released varieties with different genetic backgrounds were used to develop and validate a reliable screening method for salinity tolerance in onion genotypes at early growth stages. The study was conducted in 2 phases. The first was to determine the optimum salt concentration for screening salinity tolerance, and the second was to determine salinity tolerant genotypes and a reliable screening
