In 1971, the percentage of poorly matured flax seeds (Linum usitatissimum L.) in southern Manitoba was unusually high. This seed was discolored and tended to clump due to portions of the capsule septa adhering to the seed coat. Samples of flax seed selected from the new crop survey conducted by the Canadian Grain Commission were divided into normal and poor or weathered seeds. The poor seeds had a lower seed weight, lower percent germination, and darker oil, but an iodine number higher than the normal seeds. There were no consistent differences in oil and protein content. It appears that seeds with this type of weathering are acceptable for crushing but unacceptable for seeding.

In field and laboratory studies, flax (Linum usitatissimum L.) was frozen when 40–60% of the capsules were still green. Seed visibly frozen at this stage were of lower weight and density, darker in color, and lower in germinabihty than the fraction of the sample that was not visibly frozen. Also, oil color was darker, oil and protein concentrations and stearic and oleic acid levels were lower, and palmitic, linoleic and linolenic acid levels and iodine values were higher in the frozen than the normal seed.

Iron And Calcium

Linseed (Linum usitatissimum L.) is considered as a nutritious food because of exceptionally high alpha-linolenic acid (ALA) content, dietary fiber, quality protein and phytoestrogens. It is rich in minerals (100 g of seeds contain 350-431 mg of magnesium and 236- 250 mg of calcium) and has very low amount of sodium. It also contains anti-nutritional factors, especially phytic acid that interferes with the bioavailability of nutrients like calcium and iron. Fermentation increases the nutritional quality of foods by reducing anti-nutritional factors. Probiotic cultures viz., Lactobacillus acidophilus, Bacillus mesentericus and lactic acid bacterial isolate LAB-3 were used to produce fermented linseed beverage and the quantity of phytic acid, bioavailability of iron and calcium were estimated. Bioavailability of iron and calcium increased by fermentation. The highest bioavailable iron and calcium were observed in L. acidophilus fermentation (4.40 mg and 250.41 mg /100 g seeds, respectively) followed by LAB-3 and Bacillus mesentericus compared to raw seeds that contain 0.89 mg of iron and 125 mg of calcium /100g of seeds. Phytic acid content was high in raw seeds (1392 mg /100 g seeds) and fermentation with L. acidophilus recorded 856 mg phytic acid /100 g seeds resulting in 38.51 % reduction. LAB-3 and B. mesentericus showed approximately 32 % reduction in phytic acid content. The reduction in phytic acid content is significantly high. Fermentation using probiotic bacteria enhanced the bioavailability of iron and calcium by reducing phytic acid. Hence, this study leads to a conclusion that, microbial intervention can be adopted to reduce the anti-nutritional factors and enhance the nutritional quality of linseed.

In 26 field experiments over a 4-yr period, weed interference significantly reduced the oil content of flax seed (Linum usitatissimum L. ’Linott’) in 21 of the experiments and the iodine value of flax seed oil in 19 of the experiments, regardless of dominant weed species. Seed density and seed weight were not seriously affected by weed interference. Flax seed yields were reduced by weed interference in 25 of the experiments.Key words: Flax, weed competition, linseed oil

Important Trait

Background: Seed yield is a very important trait for selection but shows low heritability and hence is difficult to improve. Since the productivity of linseed (Linum usitatissimum L.) in India as well as Himachal Pradesh is low in comparison to other major linseed growing countries and states, improvement in cultivars for grain yield is a must. Therefore, the present study was aimed for studying the character associations in linseed genotypes for seed yield over locations. Method: The experiment was conducted during rabi 2019-2020. The experimental material for the present investigation comprised of 52 linseed genotypes grown over three locations in Himachal Pradesh i.e. Linseed Experimental Farm, CSK HPKV, Palampur (1290 m amsl), Shivalik Agricultural Research and Extension Centre, Kangra (700 m amsl) and Hill Agricultural Research and Extension Centre, Dhaulakuan (468 m amsl). Randomized block design with three replications was used. Phenotypic and genotypic correlation coefficients were worked out as per the procedure outlined by Burton and De Vane (1953) and Johnson et al. (1955). Direct and indirect effects of component traits on grain yield were worked out using correlation coefficient of various traits as suggested by Wright (1921) and elaborated by Dewey and Lu (1959). Result: Correlation studies indicated highly significant positive correlation for seed yield with 1000 seed weight (0.965**) followed by harvest index (0.801**), secondary branches (0.585**) and a significant correlation with biological yield (0.269**). Seed yield exhibited a non-significant positive correlation with seeds per capsule. However, a negative significant correlation was observed for seed yield with days to 50 per cent flowering and number of primary branches. The path coefficient analysis indicated that 1000 seed weight exhibited maximum positive direct effect with seed yield (0.741) while others had a low direct effect. The significant positive correlation of number of secondary branches and harvest index with seed yield was mainly due to indirect effect via 1000 seed weight indicating that 1000 seed weight is the most important trait for the improvement of grain yield in linseed as per the present study.

Abstract Background: Flax ( Linum usitatissimum L.) is one of the most important economic crops in the world. The lignin content of flax stems directly determines the quality of flax fibers. Flax seeds contain lignans of highly beneficial for human health.Results: To elucidate the metabolic relationship between these compounds and the regulatory nodes of their metabolic processes, third generation (PacBio Iso-Seq) and second generation (Illumina) sequencing technologies were used to sequence the transcriptomes of a pair of flax cultivars with significant differences in lignan content. It was discovered that the differential expressed genes (DEGs) are significantly enriched in the lignin and lignan biosynthesis pathways. Furthermore, there are seven genes with significant differences in expression that were annotated as UDP-glucosyl transferases ( UGTs ). We found that lignan and lignin content is significantly negatively correlated with each other. SEM observations on flax bast fibers provided further evidence of this relationship.Conclusions: This is the first full-length transcriptome analysis on flax plants using third-generation sequencing technologies, and it is also the first study to observe a negative correlation between lignin and lignan content of flax plants. Furthermore, it was found that UGTs are likely to be regulatory node genes for lignan and lignin metabolism.

Germination of flax seeds (<em>Linum usitatissimum</em> L., cv. Szafir) at 5<sup>o</sup>C was enhanced by continuous white light, gibberellin A3 (GA3), kinetin and benzylaminopurine. GA<sub>3</sub> and kinetin at physiological concentrations (10<sup>-8</sup>-10<sup>-6</sup> M) improved significantly germination in darkness. Stimulatory effect of benzylaminopurine was visible only in the light. Almost no effect of zeatin and isopentenyladenine (2iP) on germination was observed. Possible causes of this differences were suggested.

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.
