Estimates of Biochemical characteristics of linseed varieties
International Journal of Chemical Studies, 2018
The components of linseed are protein (21%), dietary fibre (28%) and fat (41%) has unique fatty acid profile. Linseed has high polyunsaturated fatty acids (PUFA) (73 % of total fatty acids), moderate in monounsaturated fatty acids (18%) low in saturated fatty acids on moisture free basis. Linoleic acid as Omega-6 fatty acid, constitutes about 16 per cent of total fatty acid whereas, ALA constitutes about 57 per cent. Due to the nutritional profile of linseed, many researchers have recognized linseed as tiny double powerhouse in disease prevention. The present investigation entitled "Estimates of Biochemical characteristics of linseed varieties'' was conducted at
Relationship among phenotypic and quality traits in indigenous and exotic accessions of linseed
Pesquisa Agropecuária Brasileira, 2016
The objective of this work was to evaluate the relationship among phenotypic and quality traits in a set of indigenous and exotic accessions of linseed (Linum usitatissimum). The experimental material consisted of 151 accessions of linseed belonging to landraces and cultivars collected from diverse agroecological zones. Five randomly chosen plants of each accession in each replicate were tagged, and data were recorded for the 12 following agronomic traits: days to flowering, days to maturity, plant weight, plant height, tillers per plant, secondary branches per plant, capsules per plant, seeds per capsule, 1,000 seed weight, harvest index, seed yield per plant, and oil content. Capsules per plant, harvest index, and plant weight played a direct and indirect major role on seed yield. High heritability, coupled with high genetic advance for plant weight, secondary branches per plant, capsules per plant, and seed yield per plant, suggests that selection based on these traits can be effective. Regarding per se performance, the following accessions can be exploited for commercial cultivation: Shweta (5.41 g), Gaurav (5.07 g), and EX-3-3 (4.77 g) for seed yield; and Shubhra (45.09%), Mukta (44.94%), Laxmi-27 (45.06%), and Shweta (44.25%) for oil content. The chemical profiling of fatty acids obtained in the present study can provide a platform for the selection of accessions for the genetic improvement of linseed.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2015
The combined SSR-SNP map and 20 QTL for agronomic and quality traits will assist in marker assisted breeding as well as map-based cloning of key genes in linseed. Flax is an important nutraceutical crop mostly because it is a rich source of omega-3 fatty acids and antioxidant compounds. Canada is the largest producer and exporter of oilseed flax (or linseed), creating a growing need to improve crop productivity and quality. In this study, a genetic map was constructed based on selected 329 single nucleotide polymorphic markers and 362 simple sequence repeat markers using a recombinant inbred line population of 243 individuals from a cross between the Canadian varieties CDC Bethune and Macbeth. The genetic map consisted of 15 linkage groups comprising 691 markers with an average marker density of one marker every 1.9 cM. A total of 20 quantitative trait loci (QTL) were identified corresponding to 14 traits. Three QTL each for oleic acid and stearic acid, two QTL each for linoleic aci...

Linseed (Linnum usitatissimum) has recently gained popularity as a health food product. It has high levels of fatty acids and minerals, giving it characteristics beneficial for functional foods. This research is a comparative analysis of the fatty acid and mineral content of 23 European linseed lines. The levels of seven fatty acids were analysed using an Agilent 6890 N GC. Alfa-linolenic acid (ALA) (C18:3, n-3) was the most predominant, ranging from 49.4 to 56.4%, followed by oleic (C18:1, n-9; 19.8 to 28.8%), linoleic (C18:2, n-6; 10.8 to 16.0%), palmitic (C16:0, 4.1 to 6.2%) and stearic (C18:0, 3.3 to 7.1%) acids. In contrast arachidonic (C20:0) and gadoleic (C20:1) acids were only found at trace levels. One-way ANOVA test showed significant differences between the lines in terms of saturated and unsaturated fatty acid content (p < 0.05). A negative correlation (r = -0.74) exists between levels of ALA and oleic acid. The levels of ten minerals (Ca, Mg, Na, K, P, Cu, Fe, Mn, Zn and B) were also determined and showed significant variability between lines. The results can be used to assist variety selection in targeted breeding programs.

The flax (Linum usitatissimum L.) is a diploid (2n = 30) autogamous (primarily self-pollinating) and an annual crop plant also called common flax or linseed. Linseed is an important oilseed crop, which belongs to the family Linaceae and order Geraniale having 14 genera and over 200 species. Almost all the species are annual herbs and some are shrubs. Linumu sitatissimum L. is the only species of the family Linaceae with non-dehiscent or semi-dehiscent capsules suitable for modern cultivation. The genetic diversity was investigated in 5 linseed lines which were collected from Oilseed Research Station, Latur. Six RAPD primers were utilized for genetic diversity analysis. In physiochemical characterization seed dimensions and biochemical properties of linseed viz. moisture, ash etc were estimated. The dendrogram produced from linseed genotypes show two main clusters. The first cluster consists of NL-356, RLC-156, Padmini, LCK-1625. The second cluster consists of sample LCK2627.These tw...

Association Analysis in Linseed (Linum Usitatissimum L.)
Journal of Biology Agriculture and Healthcare, 2014
Fifteen advanced lines of linseed (Linum usitatissimum L.) were evaluated to identify the relationship of grain yield and its related attributes during 2010-11 at Barani Agricultural Research Institute, Chakwal, Pakistan. Grain yield (kg/ha) had significant and positive association with plant height, number of primary branches plant-1 , number of capsule plant-1 , number of grains capsule-1 and 1000 grain weight both at genotypic and phenotypic levels. Therefore focusing on these traits would improve breeding efficiency of linseed in the future breeding programs. Path analysis demonstrated that plant height, number of primary branches plant-1 , number of capsule plant-1 , number of grains capsule-1 and 1000 grain weight had the positive direct effect in determining the grain yield (kg/ha) in linseed. According to these results, breeding for high grain yielding cultivars of linseed, number of capsule plant-1 should be kept in mind firstly followed by 1000 grain weight, number of grains capsule-1 , number of primary branches plant-1 and plant height.

Linseed (Linum usitatissimum L.) is becoming more and more important in the health food market as a functional food, since its seeds and oil represent a rich source of bioactive compounds. Its chemical composition is strongly correlated with, and dependent on, genetic characteristics. The aim of this study was to evaluate the variation in seed yield, oil content, fatty acid composition and secondary metabolite profiles between a low-linolenic linseed variety, belonging to the Solin-type group (Solal), and a high-linolenic traditional one (Bethune), cultivated, both as spring crops, in open field conditions of Central Italy. The achieved results pointed out the different behavior of the two varieties in terms of growth cycle, oil content, and some important yield components, such as capsule number per plant and thousand seed weight. There were also significant differences in seed composition regarding total phenols, total flavonoids, antioxidant activities as well as in carotenoid, t...
Linseed (Linnum usitatissimum L.): An oilseed crop with used in different ways
International Journal of Advanced Biochemistry Research
A field investigation was conducted at Agronomy research farm A. S. (P.G) College, Lakhaoti, Bulandshahr during rabi seasons of 2006 and 2007. The treatments consisted of combination of four cropping systems viz. chickpea sole (M1), linseed sole (M2), chickpea+ linseed 2:1 ratio (M3) and pigeonpea + linseed 4:2 ratio (M4) in main plots; two irrigations viz. two irrigations at vegetative stages (30-40 days) and flowering stage (70-75 days) (S1) and one irrigation at flowering stage (70-75 days) (S2) in sub plots and three levels of phosphorous viz. control (L1), 30 kg P2O5/ha (L2) and 60 kg P2O5/ha (L3) in sub-sub plots in split plots design replicated thrice during the rabi season. The linseed variety neelam were used in the cropping systems during rabi season. The soil of the experimental site was low in organic carbon (0.47 and 0.48 kg/ha) and total nitrogen (154.0 and 155.1 kg/ha). It was low in available phosphorus (9.2 and 9.24 kg/ha) and medium in available potassium (203.0 and 203.6 kg/ha) and sandy loam in texture having alkaline reaction (pH 7.5). The weather during the both years of the experiment was by and large normal and devoid of any extreme conditions. The net return was found to be maximum under chickpea: linseed in 4:2 row ratio with two irrigations and 60 kg P2O5/ha. (Rs. 21,632 and Rs. 22,128) followed by sole chickpea with two irrigation and 60 kg P2O5/ha. Due to relatively higher gross return. The maximum B:C ratio of 1.87 and 1.91 was obtained from chickpea: linseed in 4:2 with one irrigation at flowering and 60 kg P2O5/ha, because of reduced cost of on irrigation and higher gross return of the system.

Flax from cultivar Alexin was grown on three different water regimes: non-irrigated, half-dose and full-dose irrigated. Seeds were harvested and taken for biochemical analyses. They were found to contain low amounts of carotenoids, 7.57-12.79 mg/kg, with notable amounts of lycopene, lutein and zeaxanthin, but no detectable β-carotene. Phenolic inventory was also low, but consistent with values usually found in ungerminated linseed: 3,106-7,211 mg/kg, dominated by flavonoids (37-51%; of which minor amounts of flavanols and anthocyanins) and hydroxycinnamic acids (23-37%). Coumarins and stilbenes had low concentrations. Oil content ranged from 21.3% in non-irrigated plants to over 29% in fully irrigated ones. Ascorbic acid content showed little variation, with 985-1,187 mg/kg, while soluble sugars were 2,482-4,073 mg/kg. The concentrations of all these compounds, except for cryptoxanthin, were positively correlated to water dosage. The most affected by irrigation regime were phenolic compounds and sugars. The least influenced was ascorbic acid.
