The researches were conducted in the laboratory of oil flax breeding of the V.S. Pustovoit All-Russian Research Institute of Oil Crops, Krasnodar 2019– 2020. We studied the samples from the highly oleic collection of flax of the V.S. Pustovoit All-Russian Research Institute of Oil Crops in order to select the best ones for introduction into a breeding process to improve the existing varieties and develop new ones with a good combination of biological and economically valuable traits. The samples from our collection demonstrated variability by the general economically valuable and biological traits. Thus, difference in duration of a period emergence–maturing was from 10 to 12 days depending on year and weather conditions. Maximal plant height (63.3 сm) was noted in 2020, and minimal (38.0 cm) was similar in all years of the research. Seed yield per a plot varied from 32.5 to 112.5 g/m 2 in 2019 and from 30.0 to 175.0 g/m 2 in 2020. The highest yield (175.0 g/m2) was fixed in 2020, and minimal one (30.0 g/m2) was at the same level in all years of the research. The samples from the collection were differed by their oil content in seeds: from 44.6 to 48.7% in 2019 and from 44.8 to 49.3% in 2020. Variation of this trait by years was 4.1–4.5%, difference between years of the research was equal to 0.4%. The presence of variability in oil contents in seeds among samples from flax collection proves a possibility to conduct selections by this trait in all breeding nurseries of the laboratory. Thus, in 2020 we selected two samples with oil content in seeds more than 49.0%.
