The oil of evening primrose (Oenothera sp.) is an important source of gammalinolenic acid (GLA). GLA [C18:3Δ6,9,12] is an unsaturated fatty acid in demand for its nutritional and pharmaceutical application. Oenothera biennis L. is the primary commercial source of evening primrose oil. A study was conducted to determine if species of Oenothera, adapted to Texas, produce GLA levels comparable to O. biennis. This project identified and evaluated the fatty acid composition of eight species of evening primrose native to Texas. GLA levels of 54 accessions evaluated from collected seed ranged from 0.0% to 11.0%. Field experiments were then conducted to determine oil content, fatty acid composition, seed yield, and potential adaptation to commercial production of selected accessions. Mean GLA levels of cultivated seed from these accessions ranged from 0.0% to 10.1%. Mean seed oil content ranged from 7.3% to 21.7%. Of the species examined, O. elata subsp. hirsutissima (A. Gray ex S. Watson) W. Dietrich and O. jamesii (Torrey & Gray) demonstrated GLA levels and seed yields adequate for commercial production. Based on these results, O. elata subsp. hirsutissima and O. jamesii demonstrated sufficiently high GLA levels, oil content, and seed yields to be considered for commercial production.

Starting Point

Evening primrose (Oenothera biennis L.) is a wild species native to Eastern-North America that has recently come under cultivation as an oilseed. The oil is primarily used as a treatment for skin disorders. As a starting point for genetic improvement and domestication of this species, it was thought essential to first characterize genetic variability in Ontario evening primrose, so that members of this population may be drawn upon as a resource during cultivar development. Thirty-six wild evening primrose biotypes were evaluated in replicated trials conducted at the Delhi Research Station during 1988–1990. Seed yield, oil content and the concentration of individual fatty acids were measured. Heritability estimates demonstrated the presence of heritable genetic variation for all characters measured except the C16:1 (n–9) fatty acid. Selection for yield, oil content or fatty acid composition amongst the wild bio-types should therefore be effective. Key words: Oenothera biennis, gamma-linolenic acid, GLA, oil, fatty acid composition

Abstract Background Oil and five main fatty acid content(especially linolenic acid content (LNA) )are six main quality traits in flax, and also the important target traits in flax breeding. However, the reports on genetic map construction and QTL mapping of linolenic acid content in flax are limited, which results in low accuracy and efficiency of quality breeding in oil flax. Construction the genetic linkage map and location the QTLs to discover the stable genetic QTLs sites related to oil content and fatty acid content, so as to provide targeted targets for breeders and improve breeding efficiency. Results In this study, a final integrated map consisting of 2,239 single nucleotide polymorphism (SNP) markers on 15 linkage groups (LGs) with an average distance of 0.46 cM between adjacent markers was generated using genotyping-by-sequencing (GBS) technique. A total of 21 quantitative trait loci (QTL)s for the six traits, i.e., palmitic acid content (PAL), stearic acid content (STE), oleic acid content (OLE), linoleic acid content (LIN), linolenic acid content (LNA), and oil content (OIL) in the RIL population under three environments. One QTL cluster harbored two QTLs for LIN and LNA trait, respectively was also identified. Especially, QTL qLIN-Group12-2 for LIN and QTL qLNA-Group12-2 for LNA on chromosome 12 were detected in multi-environments. Conclusions A high-density SNP genetic map with total 2239 markers was constructed with GBS technique, The total genetic distance of the SNP map was 1032.90 cM, with the average genetic distance of 0.46 cM per marker. A total of 21 quantitative trait loci (QTL)s for the six traits under three environments were determined. One QTL cluster harbored two QTLs for LIN and LNA trait, respectively was also identified. QTL qLIN-Group12-2 for LIN and QTL qLNA-Group12-2 for LNA on chromosome 12 were detected in multi-environments. These results provide more information for determining the seed quality related candidate genes and contribute to the marker-assisted selection in flax breeding.

Rapeseed-mustard is one of the most economically important oilseed crops in India. Speciality oils having high amounts of a specific fatty acid are of immense importance for both nutritional and industrial purposes. Oil high in oleic acid has demand in commercial food-service applications due to a long shelf-life and cholesterol-reducing properties. Both linoleic and linolenic acids are essential fatty acids; however, less than 3% linolenic acid is preferred for oil stability. High erucic acid content is beneficial for the polymer industry, whereas low erucic acid is recommended for food purposes. Therefore, it is important to undertake systematic characterization of the available gene pool for its variable fatty acid profile to be utilized for specific purposes. In the present study the Indian rapeseed-mustard germplasm and some newly developed low-erucic-acid strains were analysed by GLC to study the fatty acid composition in these lines. The GLC analysis revealed that the rapeseed-mustard varieties being commonly grown in India are characterized by high erucic acid content (30–51%) in the oil with low levels of oleic acid (13–23%). However, from among the recently developed low-erucic-acid strains, several lines were identified with comparatively high oleic acid (60–70%), moderate to high linoleic acid (13–40%) and low linolenic acid (< 10%) contents. Work is in progress at TERI (New Delhi, India) to utilize these lines for development of strains with particular fatty acid compositions for specific purposes.

Low Levels

Significant variation in seed weight, oil content and fatty acid composition was found both between and within varieties in a diverse collection of 214 Linum usitatissimum accessions. Parent-offspring correlation analysis indicated that at least a proportion of the variation within several varieties was due to genetic heterogeneity. Lines were identified that had up to 46 % oil, compared with the 40 % present in the current Australian cultivar, Glenelg. High oil content was consistently associated with larger seeds. Oleic acid and linolenic acid varied between 13.3 and 25.2%, and 45.5 and 64.2 %, respectively, and were strongly negatively correlated within and between all varieties tested. The level of variation is insufficient to develop lines with less than 5 % linolenic acid by conventional hybridization and selection techniques. It is concluded that mutation breeding and interspecific hybridization are more promising approaches to the breeding of linseed genotypes containing low levels of linolenic acid.

The seed oil content and the fatty acid composition of a germplasm collection of Brassica napus and Brassica rapa currently grown in Galicia (northwestern Spain) were evaluated in order to identify potentially interesting genotypes and to assess their suitability as oilseed crops for either edible or industrial purposes. The seeds of the B. rapa landraces had higher oil content (mean 47.3%) than those of B. napus (mean 42.8%). The landraces of both species showed a similar fatty acid profile (12% oleic acid, 13% linoleic acid, 8–9% linolenic acid, 8–9% eicosenoic acid, and 50–51% erucic acid). They were very high in erucic acid content, which is nutritionally undesirable in a vegetable oil, and very low in oleic and linoleic acid contents. Therefore, they could be used for industrial purposes but not as edible oil. The erucic acid content ranged from 42% to 54% of the total fatty acid composition with an average value of 50% in the B. napus landraces whereas in B. rapa, it ranged from 43% to 57%, with an average value of 51%. Considering the seed oil and the erucic acid content together, three varieties within the B. napus collection and two varieties within the B. rapa one seem to be the most promising genotypes for industrial purposes.

Green vegetable consumption has long been considered to have health benefits mainly due to the vitamins, minerals and phytonutrients (such as vitamin C, folate, antioxidants etc) contained in a vegetable-rich diet. Additionally, green vegetables are known to contain a relatively high proportion of omega-3 polyunsaturated fatty acids (PUFAs), primarily in the form of alpha-linolenic acid (18:3n-3). However, there are no data available on the fatty acid composition and concentration of green vegetables commonly consumed in Australia. The present study determined the fatty acid content of 11 green vegetables that are commonly available in Australia. The total fatty acid concentrations of the vegetables under study ranged from 44 mg/100 g wet weight in Chinese cabbage to 372 mg/100 g in watercress. There were three PUFAs in all vegetables analyzed; these were 16:3n-3, 18:2n-6, and 18:3n-3 fatty acids. Sample vegetables contained significant quantities of 16:3n-3 and 18:3n-3, ranging from 23 to 225 mg/100g. Watercress and mint contained the highest amounts of 16:3n-3 and 18:3n-3, and parsley had the highest amount of 18:2n-6 in both percentage composition and concentration. Mint had the highest concentration of 18:3n-3 with a value of 195 mg/100 g, while watercress contained the highest concentration of 16:3n-3 at 45 mg/100 g. All 11 green vegetables contained a high proportion of PUFAs, ranging from 59 to 72% of total fatty acids. The omega-3 PUFA composition ranged from 40 to 62% of total fatty acids. Monounsaturated fatty acid composition was less than 6% of total fatty acids. The proportion of saturated fatty acids ranged from 21% in watercress and mint to 32% of total fatty acids in Brussels sprouts. No eicosapentaenoic and docosahexaenoic acids were detected in any of the samples. Consumption of green vegetables could contribute to 18:3n-3 PUFA intake, especially for vegetarian populations.

Interest in medicinal plants and fruits has increased in recent years due to people beginning to consume natural foods. This study aims to investigate the total phenolic flavonoid content, antioxidant activity, condensed tannin content, oil content, and fatty acid compositions of five local breeds of Berberis spp. from Bayburt, Turkey, and their antioxidant and antimicrobial activities. The fatty acid composition of samples was performed with gas chromatography-mass spectrometry (GC-MS), and the total fatty acid content of samples was between 6.12% and 8.60%. The main fatty acids in Berberis spp. samples were α-linolenic acid (32.85–37.88%) and linoleic acid (30.98–34.28%) followed by oleic acid (12.85–19.56%). Two antioxidant assays produced similar results, demonstrating that extracts of wild B. vulgaris L. had the highest ferric reducing antioxidant power (FRAP) (621.02 μmol FeSO4.7H2O/g) and 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) (0.10 SC50 mg/mL) values. According to principal component analysis (PCA), four components were determined. In addition, two main groups were determined according to hierarchical cluster analysis (HCA), and wild and culture of B. vulgaris L. were in different subgroups. This is the first original report about the fatty acid composition and oil content of Berberis spp. grown in Bayburt, Turkey. The obtained results indicate that B. integerrima Bunge and B. vulgaris, which have especially remarkable fatty acid content, antioxidant, and antimicrobial activity, could be potential sources for these properties in different areas of use.
