“…You et al (2014) found that both linoleic and linolenic acids have a common biosynthesis pathway, so one can increase at the cost of the other. Similar findings were also reported by Bayrak et al (2010) and Pali & Mehta (2014). The results obtained in the present study indicate that high oil content will result in high oleic acid, tending to increase linolenic acid and reduce oleic and linoleic acids.…”

“…According to Diederichsen & Fu (2008), the increase in seed weight affects oil concentration and amount per seed. The strong positive correlation observed between oil content and test weight is also in alignment with the findings of Rahimi et al (2011), andPali &Mehta (2014). The positive correlation of linolenic acid with days to maturity, plant weight, tillers per plant, secondary branches per plant, capsules per plant, and seed yield indicated that selection based on these traits would be useful in the development of varieties rich in linolenic acid.…”

“…In the present study, high heritability with moderate genetic advance was observed for all fatty acids. Likewise, Pali & Mehta (2014) found high heritability with moderate genetic advance for oil content and all fatty acid components in 48 varieties of linseed, suggesting that selection per se would be rewarding for these traits.…”

“…This shows that the increase in the oil content of the accessions will definitely enhance the oleic and palmitic acids. However, Pali & Mehta (2014) suggested that an increase in oil will lead to an increase in linolenic acid. Bhatty (1995) and Bayrak et al (2010) also observed a negative association of linoleic, oleic, and stearic acids with linolenic acid.…”

“…Although literature on the improvement of yield potential is available for linseed, few works have been carried out on improving oil quality, taking into consideration major fatty acids (Bayrak et al, 2010;Pali & Mehta, 2014). This shows the importance of characterizing the linseed germplasm for different morphological traits and for the elucidation of the fatty acid profile.…”

-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.Index terms: Linum usitatissimum, correlation, fatty acids, genetic advance, heritability, path analysis. Relações entre características fenotípicas e de qualidade em acessos de linhaça nativos e exóticosResumo -O objetivo deste trabalho foi avaliar a relação entre as características fenotípicas e de qualidade de um conjunto de acessos nativos e exóticos de linhaça (Linum usitatissimum). O material avaliado consistiu de 151 acessos de linhaça nativos ou de cultivares obtidas de diferentes zonas agroecológicas. Cinco plantas de cada acesso, selecionadas aletoriamente, foram identificadas, e foram registrados dados para as 12 seguintes características agronômicas: número de dias para o início do florescimento, número de dias para a maturação, peso da planta, altura da planta, número de perfilhos por planta, número de ramos secundários por planta, número de cápsulas por planta, número de sementes por cápsula, peso de mil grãos, índice de colheita, produção de sementes por planta e conteúdo de óleo. O número de cápsulas por planta, o índice de colheita e o peso da planta desempenharam papel importante tanto direta quanto indiretamente na produção de sementes. Altos valores de herdabilidade, associados a alto avanço genético para peso da planta, número de ramos secundários por planta, número de cápsulas por planta e produção de sementes por planta, sugerem que a seleção com base nestas características pode ser eficaz. Em relação ao desempenho per se, os seguintes acessos podem ser explorados em cultivo comercial: Shweta (5,41 g), Gaurav (5,07 g) e EX-3-3 (4,77 g) para produção de sementes; e Shubhra (45,...

Linseed (Linum usitatissimum L.) is becoming more important due to its unique nutrient profile and a source of high‐added value raw material, for both food and industrial uses. However, low productivity and lack of combined quality traits has limited its cultivation and there is an urgent need to develop improved varieties through genetic recombination of traits. In this respect 96 linseed F4 families, derived from eight contrasting parents were field evaluated during 2019–2020. A reasonable diversity among the F4 families indicated a considerable potential for improving linseed for agronomic and quality traits. Results demonstrated that strict selection for oil content, protein content, fatty acid composition and amino acid profile, with comparatively high heritability and genetic advance, is feasible and successful in F4 generation. Families with linolenic acid content as low as 9.26% and as high as 72.46% were identified. Yellow‐seeded families had higher values of phenological traits, plant height and number of capsules and lower values of seed number, linolenic acid, palmitic acid, stearic acid, aspartic acid, leucine and lysine content than the brown‐seeded types. Among the many low linolenic acid families identified those with superior yield and quality traits, offer opportunitiesfor development of new varieties that may be of high value in food industry. Also the high linolenic acid and high oil content families recognized may have genetic potentials for development of new varieties of linseed for industrial purposes. Among the parental genotypes four were found to be promising for developing superior high yielding linseeds with high quality.

A simple and cost‐effective direct transmethylation procedure for plant lipid analysis

Measuring acyl lipid content and fatty acid composition is important in plant lipid research, and direct transmethylation followed by analysis with gas chromatography‐flame ionization detection has been broadly used in various studies. However, many existing protocols are time‐consuming and labor‐intensive, and the long reaction time under high temperature may artificially change fatty acid compositions of the samples. In this study, we optimized the direct transmethylation method for seed and leaf samples with a wide range of seed and tissue sizes, oil contents, and fatty acid profiles, which can be completed in 2 h. We also demonstrated that commercial disposable pipet tips, as well as polypropylene tubes under certain conditions, could be reliably used to replace glass tubes, Pasteur pipettes, and rubber bulbs to improve efficiency. Taken together, this optimized and generalized method could be used as a reliable and less time‐ and labor‐intensive approach to analyze acyl lipid content and fatty acid profile of plant samples.
