The results of a comparative study of foreign varieties of oil flax (Linum usitatissimum L.) in the eastern steppe zone of Mongolia

The purpose of the research was to evaluate oil flax (Linum usitatissimum L.) varieties originating from different geographical and ecological regions based on their yield formation and biological properties in conditions of the Eastern steppe zone of Mongolia. Mathematical and statistical analyses were performed on yield and its component parameters. According to the study results of 2019-2022, early maturing oil flax varieties such as Flanders and Norine-67 demonstrated a seed yield of 2.02-2.22 t/ha and oil content of seeds 37.0-38.2%. Their seed yield was higher by 0.97-1.17 t/ha compared to the control and other varieties. The late maturing variety Blatall demonstrated a seed yield of 1.36 t/ha and 40.7% oil content of seeds, with a seed yield higher by 0.01-0.54 t/ha compared to the control and other varieties. Due to our results, early maturing oil flax varieties can be cultivated in the soil and climatic conditions of crop production zones in Mongolia, achieving a high yield (1.05-2.22 t/ha).
