Promising varieties of fiber and oil flax plants for agricultural technologies of Trans-Urals

Abstract

Cultivation of fiber flax and oil flax in Kurgan region is of current interest due to the presence of flax seed and straw processing enterprise – SUE Len Zauralya, Kurgan. To increase the production of highquality flaxseed oil and flax products, the level of flax production should be increased via theoretically substantiated cultivation technologies. Propagating a new variety, plant breeders consider the needs of two categories of consumers – flax producers and flax processors. Some of them need fiber flax varieties of high yield (seed and fiber) and high fiber quality resistant to diseases and lodging, adapted to conditions of Trans-Urals and Siberia. Other consumers need fiber flax varieties that meet numerous requirements of textile, construction, automotive, aviation, medical, and other sectors of the economy, and are suitable for processing by state-of-the-art flax processing equipment. The approach to develop a variety has currently become targeted and customized. Varieties grown in the study area and used as a standard showed high fiber yields: Tomsky 17 – 0.68 t/ha, Tomsky 18 – 0.69 t/ha. The results of the three-year study showed high yields of new varieties: Tost 3 – 0.98 t/ha, Tost 4 – 0.86 t/ha, Tost 5 – 0.82 t/ha. The fiber yield of these varieties was also high: Tost 3 – 0.71 t/ha, Tost 4 – 0.68 t/ha, Tost 5 – 0.66 t/ha.

Quality assessment of flax advanced breeding lines varying in seed coat color and their potential use in the food and industrial applications

“…Superior flax lines identified in this study can be used for enhanced studies to breed new varieties with a wide range of potential customers in the food market and industry (Table S2 ). Oil content and its fatty acid composition are the main components of flax genotypes, essentially determining its value and market end-use for nutritional or industrial purposes [ 9 , 42 , 43 ]. Hence, modifying fatty acid profiles to improve oil quality is an important and evolving issue in flax research [ 9 , 44 ].…”

Assessment of fiber flax varieties according to the parameters of ecological plasticity in the conditions of the Ural region of the non-chernozem zone of Russia

“…At the same time, it is necessary to consider the needs of two categories of consumers -producers and processors of flax. This is important for reducing the economic, environmental, and social costs of agricultural production [32,33].…”

Selection of promising lines for yield and quality traits in advanced segregating generation of linseed

“…Oil content and its fatty acid composition are the main parameters for linseed genotypes, defining to a large extent its value and market end use (Ceh et al, 2020;Gajardo et al, 2017;Porsev et al, 2020). The scatter plot of F4 families and parental genotypes drawn (Figure 4) for linolenic acid content versus oil content specifies this relation.…”
