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.

Summary Introduction: The Institute of Natural Fibres and Medicinal Plants (INF&MP) is involved in the protection of the genetic resources of flax (Linum usitatissimum L.) and hemp (Cannabis sativa L.). In 1998–2000, the INF&MP conducted research titled “Collection and evaluation of flax and hemp cultivars and ecotypes”. Poland participates in the programme, financed by the Ministry of Agriculture and Rural Development because our country has signed the Convention on Biological Diversity. Objective: The objective of the research was the evaluation of the genetic resources of 23 accessions of flax. The characteristics data for flax accessions are presented according to traditional methodology and according to the methodology for developing the International Flax Data Base. Methods: Field trials were carried out in 1998–2000 in the experimental station in Wojciechów, located in the Opolskie region. The objective was to evaluate the morphological traits, biological features and seed yield of 23 accessions of flax. The research included the following genotypes of Linum usitatissimum L. according to type of use: 12 linseed varieties, three landraces, one accession of unknown type of use, six fibre varieties and one genotype of both types of use. Results: The total plant length of Linum was short for 12 accessions of flax, medium short (7) and medium (4). The technical length was short (17 accessions), medium short (3) and medium (3). The stem thickness for all accessions was medium, i.e. between 1.2 and 2.0 mm. The panicle length was short (12 accessions), medium (10) and long (1). A number of primary lateral branches of the stems of all flax accessions was medium (4–8 branches). The 1000 seed weight was low for 21 accessions of flax and very low in two genotypes: Currong and UKR 97 104. The size of the corolla (flower) was small (9), medium (12) and large (2) – varieties: Martin and Maxigold. The petal colour of the corolla was blue (11), light blue (8) and white (4) – Crystal, Hella, Kreola, Achay. Conclusions: Morphological characterisation of the stamen showed that accession K-1390 was segregating because the anther colour was bluish and greish. The highest resistance to lodging was observed for Abby, Peak and Olinette. The following accessions of flax were very resistant to Fusarium: Martin, UKR 97269, Kijewskij and Ukraińskij 3; resistant to Fusarium: Abby, Peak, Olinette, Crystal, Gold Merchant, Currong and Ukraińskij 2. The following varieties were very susceptible to Fusarium: Hella, Kreola, Maxigold and Achay. These varieties should not be used for cross breeding. The best average seed yield in 1998–2000 in Wojciechów was found in the following accessions of flax: Abby (191%), Gold Merchant (162%), Currong (161%), Olinette (151%), PEAK (148%), UKR 97269 (148%), Crystal (138%), Ukraiński 3 (132%), Martin (130%), Pacific (110%) and Ukraiński 2 (103%). These varieties are particularly valuable for flax breeders.

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.

The results of researches on the influence of the terms of harvesting varieties of fiber flax varieties of different ecological and geographical origin on the productivity of fiber and seeds are given. The optimal harvesting dates for the varieties of Zhuravka, Esman and Kamenyar have been established, depending on the target direction of product use. The highest yield of all fiber of fiber flax was obtained in early yellow maturing term depending on the grade of 3.37 t / ha in the Esman variety and 2.58 t / ha in the Kamenyar variety, and the harvesting of these varieties into other phases of ripeness leads to a decrease of 3,1-15,1%. For the Zhuravka variety, the best harvesting period for obtaining the maximum yield of fiber is the phase of green stiffness – 2.78 t / ha).
