Linseed or flax (Linum usitatissimum L.), a multiple purpose crop valued for its seed oil, fibre, probiotic and nutraceutical properties, is adapted to different environments and agro-ecologies. Modern breeding techniques using only limited number of selected varieties have resulted in a loss of specific alleles and thus, reduction in total genetic diversity relevant to climate-smart agriculture. However, well-curated collections of landraces, wild linseed accessions and other Linum species exist in the gene banks and are important sources of new alleles. This review is primarily focused on the studies of genetic diversity of linseed species and evaluation related to tolerance to abiotic and biotic stress factors that could be useful for improving linseed through future promising breeding programs in addition to briefly discussing different morphotypes and nutraceutical importance. Wide diversity in linseed germplasm indicates a considerable potential for improving this crop for both agronomic and quality traits required for developing climate-resilience tailored to specific environments. Recent release of the flax genome sequence coupled with wide range of genomic and analytical tools in public domain has furthered understanding of molecular mechanisms for detailed study of the genes underlying flax adaptation to stress and diversity in commercially important accessions. Important climate related traits and their constituent genes are presented and key developments for the future highlighted emphasizing the urgent need to increase the use of genetically diverse germplasm to meet the emerging challenges in agricultural production and to conserve valuable genetic resources for the future.
