Chromosome-scale assembly of European flax (Linum usitatissimum L.) genotypes and pangenomic analysis provide genomic tools to improve breeding

2025 · Arvalis

Decoding the genome of cultivated species is one of the key starting points for supporting marker-assisted selection to accelerate breeding programmes. To date, five to six flax genotypes, including fiber flax, linseed and related wild flax, mainly from Canada, China and Russia, have been sequenced and assembled. But no genome assembly was available for Western European flax cultivar, although France is the world's leading producer of fiber flax (85% of world production). The Canadian oilseed flax cultivars CDC Bethune have been mainly used as reference for studies and breeding activities. The best assembly to date was the Chinese fiber Yiya5 assembly, which had the best metric of all the flax genome assemblies available.
