In the comparative variety testing it was evaluated promising material of fiber-flax (Linum usitatissimum L.). The aim of the work was to identify the most valuable cultivar fiber-flax according to their  economic and biological characteristics, and adaptability to adverse environmental factors.  Valuable forms of fiber-flax on the main economically significant features were identified in the Smolensk region. The total length of the stem of A-11 and L-198 exceeded the standard S-108 by 8 - 10%. The duaration of the growing season in all studied varieties was 5 days longer than that of the standard variety.   L-198 exceeded the standard S-108, both in yield of flax straw and fiber content in the stem, the excess was 9 and 3%, respectively. The highest yield of flax seeds (0,58 t/ha) was also in L-198 (21% higher than in the standard). The yield of long fiber in the stem of this sample was 20,1%, which is 0,8% higher compared to the standard. The calculation of the economic efficiency of cultivation of the L-198 variety for fiber-flax seeds also showed its advantage over the S-108 standard.

Linum Usitatissimum L

Creation of the initial material of fiber flax (Linum usitatissimum L.) with marker signs is a promising direction of breeding, which determines the efficiency of breeding varieties with improved properties. The purpose of the research was to create initial flax material for obtaining seeds with a marker sign (yellow color) and increased weight. The studies were carried out at the Federal Research Center for Bast Fiber Crops in 2015–2018. In our work, we used flax varieties ‘Smolich’, ‘Antey’, ‘C-108’, as well as forms obtained from these varieties. These varieties were used as control. Nurseries were laid under conditions of a leveled agricultural background. Seeds were sown in a square way (2.5×2.5 cm). The experiments were conducted according to the current methods, including phytopathological testing. Soil – sod-podzolic, medium loamy, cultivated. Selyaninov Hydrothermal Coefficient (HTC) in 2015 was 1.3; in 2016 – 2.2; in 2017 – 1.8; in 2018 – 1.3. During the flax plants selection, we obtained three forms with yellow-colored seeds. Yellow-seeded form No. 1 was valuable from the breeding point of view. It exceeded standard variety ‘Smolich’ in seed weight by 0.8 mg (16.0%), in seed yield – by 0.06 t/ha (9.8%). Form No. 1 belongs to the improved fiber flax line. Form No. 3 had a higher seed mass (5.6 mg) compared to standard variety ‘C-108’. In terms of seed yield and 1000-seed weight, this form exceeded the standard by 0.08 t/ha or 14.8% and 0.49 g or 10.6%, respectively. Form No. 3 is a breeding material for creating varieties of bilateral use. Form No. 2 had signs of the oil flax line. It exceeded standard variety ‘Antey’ in seed yield by 0.18 t/ha (40%); 1000-seed weight – by 0.53 g (11.2%). The created material has a breeding value. It was transferred to the bioresource collection of flax for its replenishment, to the bank of the characteristic collection and was additionally included in the breeding process.

Du, G.-H., Liu, F.-H. and Rowland, G. 2015. Fiber cell development and fiber yield of flax (Linum usitatissimum L.) affected by the seasonal temperature pattern. Can. J. Plant Sci. 95: 1215–1220. Three fiber flax cultivars ‘Ariane’, ‘Argos’ and ‘Viking’ were cultured in growth chambers under three seasonal temperature patterns (STPs) [parabolic (P), anti-parabolic (AP) and quasi-horizontal (QH) configurations]. The effect of STP was studied on fiber cell development and on fiber yield. The results indicated that, compared with the quasi-horizontal seasonal temperature pattern (QH-STP), the size of fiber cell cavity (SFCC) and fiber content (FC) decreased under parabolic seasonal temperature pattern (P-STP). However, the size of fiber cell (SFC) and SFCC decreased, but the number of fiber cells per bundle (NFCB) increased under anti-parabolic seasonal temperature pattern (AP-STP). Moreover, there was a significant positive correlation between fiber weight (FW) and width of fiber bundle (WFB), also between FC and NFCB. Considering the response of fiber flax cultivars to the different STPs, ‘Ariane’ had smaller SFC and SFCC, thinner thickness of fiber cell wall (TFCW) under AP-STP, and smaller SFCC and thicker TFCW under P-STP than under QH-STP, while ‘Argos’ had smaller SFC and SFCC, and higher NFCB under AP-STP, and smaller SFC under P-STP than under QH-STP. However, STPs had little effect on the fiber cell development of ‘Viking’. All three cultivars had high FC under AP-STP than under P-STP. These observations indicate that the fiber cell development and fiber yield of flax were related to the STP and suggest that AP-STP are the most favorable temperature conditions for fiber flax growth.

Abstract. The purpose of the research was to assess the average-ripe varieties of fiber-flax Smolensk selection on the complex of economic and useful features. The research was carried out on sod-podzolic, medium-loamy, medium-cultivated soil in the experimental fields of the Smolensk Institute of agriculture (ex. Smolensk state farm). The object of the study are 3 medium-ripe varieties of fiber-flax selection of Smolensk ISH: S-108 (on average for 2007–2009), Smolich (on average for 2011–2013) and Impul’s (on average for 2016–2018). Tab experiments, observations and records were performed according to generally accepted methods. The system of agriculture is typical for the Smolensk region. Results and practical significance. The article presents a comparative characteristic of the studied varieties of fiber-flax. It was established that all varieties belonged to the group of medium-ripened with a vegetation period of 80 days. Varieties S-108 and Impulse (80 cm) were the tallest along the length of the stem. Smolich lagged behind in growth from the above varieties on 5 sm. All varieties had a high resistance to lodging and optimal density of standing plants before harvesting. The highest yield of flax seeds and flax straw was noted in the variety S-108 (7.5 and 53.5 c/ha, respectively). The yield of all fiber varieties S-108 and Impul’s were at the same level (14.9 and 14.8 c/ha, respectively). The variety S-108 (29.0 % and 22.3 % respectively) was also distinguished by the content of all fiber in the stems and the yield of long fiber. According to the qualitative characteristics, the most durable fiber was in the Smolich variety (33.4 kg/s). The flexibility of all the studied varieties was approximately at the same level. Scientific novelty. Improvement of already existing varieties of fiber-flax with ecological plasticity.

Flax (Linum usitatissimum L.), grown throughout the world for millennia. It is a multipurpose agricultural crop that can provide food, fuel and fibre. An agro-morphological characterization based on 13 traits of 26 flax accessions was carried out during the Rabi season 2017-2018 at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Rangpur. The field experiment was laid out in a randomized completed block design having four replications. Flax seeds were sown in 3.0 m × 0.6 m plot with continuous line sowing (two lines). The seed germination (%) and vigour indices of all flax accessions varied from 44.1 – 77.7 and 44.1 – 119.4, respectively. A significant variation in all growth and yield attributing descriptors was observed except 1000-seed weight of flax. Among the accessions, BD-10708 possessed the highest seed yield (182.9 g plant–1) and yield attributing descriptors viz., number of capsules plant–1 (142) and seeds plant–1 (513) of flax. The performance of the local accesson Ulipur was observed poor compared to some of the test accessions of flax. Some of these flax accessions could be used as breeding materials in varietal developmental and improvement programmes with higher yield potentials of flax in Bangladesh.

Flax (Linum usitatissimum L) yield of stem and seeds and them quality is influenced by a number of harmful diseases but investigation about pathogens in recent years have not been done in Latvia. Each stage of development of disease is important in the pathogen life cycle and requires certain condition. Goal of this study have identify possibilities of the pathogens and were assess disease severity depending on the genotypes on flax in variable environmental conditions. The resistance to the diseases for 24 flax genotypes and standard variety ‘Vega 2’ were evaluated. The field trials have been carried out over the period from 2015 to 2016 at the Research Centre of Priekuli, part of Vilani in Latgale. Disease progress was measured every week, and for each treatment, severity of diseases index and the area under the disease progressive curve (AUDPC) were calculated. The flow cytometry method for detection of flax pathogens was developed. The Fusarium avenaveum was dominating disease and statically significant in both vegetation periods. In 2015 were identified statically significant (p
