Discovering new genes for alfalfa () growth and biomass resilience in combined salinity and infection through GWAS.

Salinity and infection represent significant challenges for alfalfa cultivation in South Africa, Europe, Australia, and, particularly, Tunisia. These constraints have a severe impact on both yield and quality. The primary aim of this study was to establish the genetic basis of traits associated with biomass and growth of 129 genotypes through genome-wide association studies (GWAS) under combined salt and infection stresses.
