As Kazakhstan expands its oilseed cultivation, particularly with flax, it is essential to understand how different flax varieties and growth conditions impact the quality of oil and fiber. Despite a recent slight decrease in flax sown area, its dual-purpose value remains significant. Therefore, this study was conducted in the growing seasons of 2022 and 2023 to determine the fatty acid composition of the oil and the quality of the fiber of various varieties of oil flax cultivated in the conditions of the Akmola region, northern Kazakhstan. Different varieties of Chinese selection - UF1, UF2, UF3, UF4, UF5, UF6, and zoned flax cultivar - Kostanay Yantar, Leader and Iceberg were examined in this study. A randomized complete block design with three replications was performed in the experiments. There were eight varieties and samples in total, with the standard being the zoned flax variety Kostanay Yantar. Germination of seeds of oil flax ranged from 66.2 to 84.8 percent. Among Chinese selection varieties, the best germination rate was obtained for the UF0 2 in the value of 92.4%. The specified variety in terms of field germination exceeds other varieties of foreign selection by 9.9%. Under regional conditions. The significance level of the results attained indicated that they were not statistically significant (y=14.256ln (x)+29.509), which was explained by the small sample size. It should be noticed that the achieved correlation results were positive, that was, when the values of one parameter increased, the compared parameter also increased significantly.
