Linseed (Linum usitatissimum L.) is an important oilseed crop recognized for its rich phytochemical composition, including bioactive compounds such as lignans, flavonoids, and phenolic acids, which contribute to its therapeutic applications. This study aimed to investigate the genetic variability among 15 linseed genotypes and its impact on the phytochemical composition. A combination of molecular markers and high-performance liquid chromatography (HPLC) was employed to assess genetic diversity and the concentration of key bioactive compounds. A significant level of genetic variation was observed across the genotypes, with genotypes G4, G8, and G5 exhibiting the highest concentrations of lignans, flavonoids, and phenolic acids, respectively. The correlation analysis revealed a strong association between genetic diversity and the concentration of flavonoids and phenolic acids, suggesting that selective breeding could enhance these beneficial compounds. However, the correlation between lignan content and genetic diversity was weak, indicating that environmental factors may have a more substantial impact on lignan production. The study’s findings underscore the potential of using genetic diversity to improve linseed's nutritional and medicinal value through breeding programs, as well as the importance of optimizing environmental conditions for maximizing phytochemical content. The results provide a foundation for future research in linseed breeding and agro-management practices aimed at enhancing the health benefits of linseed-based products.
