Flax is one of the most important crops, both in Russia and in other countries. In modern conditions, fibre flax is considered as a strategic crop in Russia, since it is able to replace raw cotton, which has moved into the category of imported raw materials.
Oil flax is used for the production of seeds, which are characterized by valuable nutritional and therapeutic properties. The flax collection created at the Federal Research Centre for Bast Fiber Crops is one of the largest in the world and covers almost all the genetic diversity of the crop. The collection was screened for resistance to Fusarium wilt and highly resistant samples were identified. Phenotyping of 306 accessions was performed three times at experimental station in Torzhok, Russia: in 2019 and two times in 2020. Here we present the results of GWAS for 306 accessions from this collection.Sokolkova_flax
