Cultivar of oil flax Y 220

The oil flax cultivar Y 220 is developed by a method of individual selection from a line k-4165 at severe background after 6-field flax mono-crop. It was estimated by resistance to fusariose in epicentrum of fusariose infection and to flax sickness at monocrop cultivation. Due to results of variety trials for 2019-2020, the cultivar Y 220 exceeded the standard cultivar FLIZ by yield by 0.77 t per ha. Plant height is 80-90 cm. Vegetative period is 75-80 days. Weight of 1000 seeds is equal to 6.02-6.06 g. Seeds color is brown. Oil content is 44.4%; linolenic acid content is lowered (23.3%). The cultivar Y 220 is differed with full resistance to flax sickness and high field resistance to fusarium wilt. This makes it possible to cultivate it in short crop rotations and at monocrop.
