Abstract: In this work the results of long-term evaluation of lines of flax genetic collection created in VIR are generalized. A wide variability of fibre productivity and quality characters, and also stability of their manifestation in varying environment is revealed. The genotypes possessing contrast traits of productivity, quality and stability of their display in different years are distinguished. Dependence of correlations between the evaluated characters on the environment parameters is detected. The described lin… Show more

“…Correlative variability, as a prediction method for selection, is widely used in flax breeding (Rennebaum et al, 2002;Diederichsen, Raney, 2006;Diederichsen, 2007;Brach et al, 2010). Calculation of the correlation coefficients allowed us to identify the ratio of chlorophyll content to plant height (R 2 = 0.65), the number of leaves (R 2 = 0.36) and area of leaves (R 2 = 0.19) under controlled conditions (Fig.…”

Genetic diversity of plants increases the possibility of choice and provides higher adaptability of plants to adverse environmental conditions. Flax (Linum usitatissimum L.) is one of the crops requiring attention and introduction in agricultural production. In Siberia, Russia already in 1908 the first experiments with flax were started in Tobolsk province. In the 20 th century this branch was developed on the farms of Tyumen region. Heat resources, agrochemical properties of soils, water supply are adequate for the cultivation of this crop in the northern latitudes.The study was aimed to explore the effects of seed treatment with phosphemidum on chlorophyll content and morphometric parameters of flax seedlings and plants. Seventeen samples of fibre flax and three samples of linseed of different origin (Russia, Belarus, Ukraine, Canada, Czech Republic, France and Germany) from the collection of the Institute of Biology of Tyumen State University were studied. Air-dried seeds were treated with the solution of chemical agent phosphemidum in concentrations of 0.005, 0.01 and 0.1 %. Laboratory experiments revealed differences in morphometric parameters of plant seedlings. The response to seed treatment with mutagen was studied by the variability of chlorophyll content in the leaves. The samples were found to differ in the dynamics of chlorophyll accumulation by the stages of ontogenesis. All samples reacted to the increase of phosphemidum concentration by the decrease in chlorophyll content in leaves.

The results of the study of 30 flax samples of different ecological and geographical origin from the collection of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) are presented. The varieties of the Russian selection 14, Chinese 6, Ukrainian 5, French 4, Belarusian 1 have been investigated. The influence of genotypes and weather conditions on the manifestation of economic traits by multivariate analysis of variance has been established. Field studies were conducted in the sub taiga zone of the Tomsk region in 2015-2017. Natural and climatic conditions met the requirements for the cultivation of fiber flax. By total and technical stem length the best varieties of the Chinese selection Heiya 4 (K-8485), Sxy 7 (K-8689), the Russian hybrid Tomsk 16 * Success (K-8544), the French variety Drakkar (K-8493), the Ukrainian Glazur (K-8695), 66-72 and 60-66 cm respectively, were significantly higher than the standard Tomsk 16. According to the fiber content in the technical part of the stems (38-40%) the following varieties were the leaders: the Russian selection P-3989 (K-8672), A-236 (K-8692), M-249 (K-8693), the French selection Alizee (K-8494), Agatha (K-8492), Melina (K-8495), and the Ukrainian selection Vruchy (K-8694), were significantly above the Tomsk 16 standard. By the fiber mass (91-104 mg) the French varieties Drakkar (K-8493) and Alizee (K-8494), the Ukrainian varieties Vruchii (K-8694) and Glazur (K8695), the Russian varieties A-236 (K-8692) and M-249 (K-8693) reliably exceeded the Tomsk 16 standard by 6-44 mg. The flax varieties of the Russian selection P-3989 (K-8672), Dobrynya (K8504), A-236 (K-8692), the Chinese Heiya 4 (K-8485), Heiya 13 (K-8486), Tyy 13 (K-8687), the French Agatha (K-8492), Drakkar (K-8493), Alizee (K-8494), Melina (K-8495), and the Ukrainian Gladiator (K-8505) and Vruchiy (K-8694) were recognized as promising and were included in the breeding process as male seed parents. The resulting hybrid material has been on trial in the selection nursery from 2017 and the second year of breeding from 2021.

The current paper has presented the results of ecological and geographical testing of oilseed flax varieties in the Kostroma region. The purpose of the current study was to identify promising oilseed flax varieties adapted to the soil and climatic conditions of our region. The objects of the study were 5 varieties ‘Biryuza’, ‘Rucheek’, ‘Nilin’, ‘Fliz’ and ‘VNIIMK 620’ (as the standard variety) developed in the of the ‘FRC VNIIMK named after V.S. Pustovoit’. The trials were laid down, recorded and observed according to the methodology of a field trial, as well as in accordance with the recommendations for conducting field agrotechnical experiments with oilseeds. There has been established a reaction of varieties to the agrometeorological conditions of the region. The vegetation period of flax ranged from 103 to 110 days. There was revealed that these varieties of the middle-maturing group, showed themselves as late-maturing during the study. On average, over the years of study, the highest seed productivity was given by the varieties ‘Biryuza’ (1.16 t/ha) and ‘Fliz’ (1.12 t/ha). All varieties had a high positive correlation between seed productivity and plant density per m2 . The largest oil content was identified in the varieties ‘Biryuza’ (50.2%) and ‘Rucheek’ (50.3%). The largest oil productivity was given by the varieties ‘Biryuza’ (0.58 t/ha) and ‘Rucheek’ (0.56 t/ha). The largest seeds were formed by the varieties ‘VNIIMK 620’ (7.92 g) and ‘Fliz’ (8.34 g). There has been established that two varieties ‘Biryuza’ and ‘Rucheek’ are the best ones among the studied varieties according to the main economically valuable traits. In the soil and climatic conditions of the Kostroma region, there can be formed complete flax seeds with high varietal and sowing qualities despite the increase in their vegetation period length.
