FIELD: plant selection and genetics. SUBSTANCE: invention relates to method of producing flax apomictic haploids that involves treatment of plant at the phase of appearance of the first flower with dimethylsulfoxide solution (concentration is 1%) as measured 0.1-0.2 ml per a single plant. Invention ensures to obtain flax apomictic haploids in the large amount (by 5-10-fold more as compared with known methods) and can be used for acceleration of process of development of flax homozygous strains by using apomictic haploids. EFFECT: increased yield of haploids, minimal labor consumption. 1 tbl
