Barley Breeding: QTL and GWAS for Agronomic Traits
Received Date: May 01, 2025 / Published Date: May 29, 2025
Abstract
Quantitative Trait Loci (QTL) mapping and Genome-Wide Association Studies (GWAS) are extensively applied in barley (Hordeum vulgare L.) breeding to identify genomic regions associated with key agronomic traits. Research presented focuses on yield, stress tolerance (drought, frost, salinity), nitrogen use efficiency, disease resistance (powdery mildew, leaf rust), malting quality, and seedling vigor. Advanced genotyping technologies, including high-density SNP arrays, facilitate precise mapping and marker development for marker-assisted selection, accelerating the creation of improved barley varieties with enhanced performance and resilience, contributing to sustainable agriculture.
