“…Interestingly, the fatty acid profile varied not only among cultivars but also within the same cultivars collected in different years, suggesting that climate had a significant influence (mainly hydrothermal conditions) [29]. This phenomenon is also supported by a study on 198 Ethiopian linseed cultivars of flax [30], as well as nine Kazakhstan varieties [31]. Zou et al [28] compared several Chinese varieties of linseed and fiber flax and showed great variation in linolenic acid content in these varieties.…”

Flax, Linum usitatissimum, cultivars are grown throughout the world. Flax oil is a dietary source of polyunsaturated fatty acids, vitamin E, as well as phospholipids, sterols, and phenolic acids. Linseed plays a pivotal role in protecting cells from oxidative damage associated diseases, i.e., atherosclerosis, neurodegenerative disorders, cancer, and inflammation. In this study, two groups of L. usitatissimum seeds were used to evaluate and compare the content and composition of tocochromanols (vitamin E) and fatty acids. Group I included accessions originating from Poland and the Ukraine, while Group II encompassed worldwide flax cultivars (such as from the United States, Argentina, and Italy). A comparison of the tocochromanol profiles showed a higher content in Group I, although there were no significant differences in tocopherol content and composition between the genotypes within this group. All accessions in Groups I and II contained γ-tocotrienol and plastochromanol-8, which confirms the high nutritional value of flaxseeds. The composition of fatty acids varied depending on the varieties, with linolenic acid showing the greatest discrepancy. Based on the tocochromanol content and fatty acid composition, we conducted a principal component analysis (PCA) and cluster analysis, which revealed a greater similarity among the accessions in Group I. An analysis of the tocochromanol and fatty acid composition of flaxseeds is important from an agronomic and medicinal perspective and can be used to select the most appropriate flax cultivar.

“…The study [25] note, that the change in oil content depends on the genotypic differences. However, some [26], [27] note, that the range of variation not only within the genotype but also with regard to the climatic conditions of cultivation including water availability influence the oil content of flax seed. In general, similar results could find in our study.…”

Genetic diversity evaluation in a breeding program is essential produce robust, resilient crop varieties with improved agronomic characteristics under environmental challenges in the sustainable agro-ecosystems. Knowledge and full potential on the impact of genotypes and growing conditions on flax yield traits still incomplete. The aim of this study was to evaluated the influence of hydrothermal conditions on the development of agronomic important traits of flax, analysed agronomic characteristics and identified perspective genotypes for pre-breeding. Field investigations were carried out from 2014 to 2017 for agronomically important traits of flax. In the study was evaluated flax population with Latvian origin in 24 fibre flax genotypes and ‘Vega 2’ (ST) as the standard variety of Lithuanian origin under Latvian meteorological conditions. Correlation between flax genotypes of the agronomically important yield traits and years of the hydrothermal coefficients during the growth period were analysed. According to the results obtained that most of genotypes the significant higher plants stem yield, total plant height, technical plant height, number of seed vessels per plant were measured in the growing seasons with high humidity. However, the higher seed yield and 1000 seed weight were measured in the driest year. The correlation between flax fibre content, seed number per seed-vessel, oil content and humidity level differed in dependence on genotype. The coefficient of variability between years was higher for of stem yield when compared with seed yield. The flax genotypes ‘S13/5-7/5-93’ exhibited more stable, highest stem yield (840.0 g m-2) and high seed yield (162.2 g m-2). The flax was identified 80% samples the short and 20% the medium vegetation period.

“…A number of studies confirm that not only seed yields, but also changes in oil content depend on genotypic characteristics. In the conditions of the dry steppe zone of Northern Kazakhstan on the dark chestnut soils of the Akmola region, it was established that the formation of oil depends on the climatic conditions of cultivation and on the sum of the active temperatures during seed maturation (Gordeyeva and Shestakova, 2018). For the dry steppe zone in terms of plasticity and stability of oil content 'VNIIMK 620', 'Lirina', 'Karabalyksky 7 'varieties are highly valuable, and 'Severny', 'Biryuza', 'Kazar', and 'Ilyich' varieties are valuable.…”

Studying the reaction to the abiotic conditions of the Middle Urals in 16 varieties of oil flax will allow to adapt the culture: increase its productivity and product quality. As a standard, the variety ‘VNIIMK 620’ was sown. The experiments were laid on sod-podzolic medium loamy soil in the grain-grass rotation after winter crops during 2012-2015. During the years of research, the plow layer of the experimental plots had different humus contents - medium and high, mobile phosphorus and exchange potassium - medium and very high, exchange soil acidity - slightly acidic and close to neutral. To a greater extent, by 91.5%, the change in the seed yield of the studied oil flax varieties depended on the abiotic conditions of the growing season; the share of the influence of the genotype of the variety in the formation of seed yield was 3.0%. Meteorological conditions during the years of the experiments were characterized by large fluctuations in the average daily air temperature and the amount of precipitation that fell over the months, in consequence of this the seed yield of flax oil varied in wide range over both varieties and years of study. The most favorable abiotic conditions for the formation of oil flax seeds were formed in 2014, when, during the ripening period of the seeds optimal meteorological conditions have developed with hydro thermic factor of 1.0. This contributed to obtaining the highest seed yield in 2014 - 218 g/m2. On average, over four years of research, the same response to abiotic conditions with seed yield was formed in ‘VNIIMK 620’ varieties from Russia, ‘Clark’ varieties from Holland and ‘Barbara’ from Hungary. The most plastic grade is ‘Clark’ with a plasticity coefficient bi = 1.33. The most stable seed yield is the ‘Norlin’ variety with a stability coefficient of 32.2. Russian varieties ‘LM-96’, ‘N 3829’ and foreign varieties ‘Norlin’, ‘Atalante’ proved to be the most adaptable to cultivation conditions in the agroecological conditions of the Cis-Ural region and can be considered promising in terms used as starting material in the breeding process.
