“…Such food must have a long shelf life, which is achieved by lowering the α-linolenic acid content and increasing the linoleic content. From the end of the 20 th century, flax breeding technologies developed more rapidly [49] and now include hybridization [50], introduced mutation, interspecific hybridization, utilization of malesterility, ploidy breeding, tissue culture, gene transformation, marker assisted selection, etc. [49].…”

Introduction and objective. The aim of the study was to determine the content of five essential fatty acids in seed oil from 84 genotypes of flax (Linum usitatissimum L.) from the collection of genetic resources, stored at low temperatures of the long-term storage of the Plant Breeding and Acclimatization Institute in Radzików. The following fatty acids were evaluated: α-linolenic, linoleic, palmitic, stearic and oleic. The ranges of variability of fat content in flax seeds were also determined. In addition, it was calculated how many times the α-linolenic acid content is bigger than linoleic acid in seed oil of each accessions of flax. Materials and methods. The research material consisted of 84 genotypes of common flax (Linum usitatissimum L.), collected and included in the samples. The fat content was determined by infrared analysis (calibration performed on the basis of a seed sample at IHAR-PIB in Poznań) by means of a NIRS 6500 spectrophotometer with a reflection detector within the range of 400-2500 nm. Results. The ranges of variability of individual fatty acids of 84 flax accessions are as follows: α-linolenic acid: 48.4%-58.9%, linoleic acid: 10.3%-17.3%, palmitic acid 4.2%-6.6%, stearic acid 2.6%-5.1% and oleic acid: 17.0%-26.7%. The fat content in the seeds of the evaluated accessions ranged from 39.8%-44.8%. Conclusions. Flax seeds from the collection of the genetic resources are an excellent ingredient in food because they contain a large amount of α-linolenic acid. Dietary supplementation with linseed, also containing large amounts of α-linolenic acid and small amounts linoleic acid, allows provision of the body with the necessary ratio of the diunsaturated (n-6) to the triunsaturated fatty acid (n-3). In order to protect health, it is necessary to supplement the diet with a unique α-linolenic fatty acid that are present in only a few food ingredients.

Fungal diseases are one of the limiting factors of flax (Linum usitatissimum L.) production in variable environmental conditions. The expansion of fungal diseases depends on the plant resistance, pathogen population's ability to overcome this resistance and plant growth conditions. This study is aimed to estimate the flax resistance to fungal diseases in relation to environmental factors under the field conditions and identify the most promising accessions for plant breeding. A total of 24 fibre flax genotypes of local origin were investigated. The flax genotypes with different resistance to the most common diseases were identified using the area under the disease progress curve (AUDPC) for plants and resistance index (RI): in the growing season with high humidity there were identified the genotypes that were more susceptible to wilt (caused by Fusarium oxysporum f. sp. lini), pasmo (caused by Septoria linicola) and anthracnose (caused by Colletotrichum lini), and in the growing season with drier conditions there were identified the genotypes that were more susceptible to stem break, browning of flax (caused by Polyspora lini), powdery mildew (caused by Oidium lini) and fusarium browning (caused by Fusarium spp.). The highest incidence of the causal agents Fusarium spp. and Colletotrichum lini on the flax seeds was identified in high humidity conditions. The most valuable flax genotypes S13/5-7/5-93, S64-17-93, T11-13/3-1-94 and L11-11/11-97 exhibited relatively high complex resistance to diseases and high yield compared to the standard cultivar 'Vega 2'. The genotype 'Rezeknes' exhibited higher resistance to the powdery mildew at the seedling stage and complete resistance at the adult plant stage compared to all accessions.
