“…The linoleic acid content of the oil 54.80 g/100 g was comparable to that of the sunflower oil 48.3-74.0 g/100 g , corn oil 34.0-65.6 g/100 g and cottonseed oil 46.7-58.2 g/100 g 17,18 . The oleic acid content of the oil 18.66 g/100 g was extremely lower than that of the peanut oil 35.0-67.0 g/ 100 g and camellia oil 74-87 g/100 g 19 . The unsaturated fatty acids content USFA was 80.12 g/100 g, among which polyunsaturated fatty acids content reached up to 60.41 g/100 g. Therefore, highland barley bran oil was beneficial to human health.…”

Introduction As one of the most ancient cereal crops, hulless highland barley qingke is the only crop that can be cultivated in Qinghai-Tibetan Plateau, which has an average elevation of 4000 meters. The extremely cold, hypoxia and extensive UV radiation condition of Qinghai-Tibetan Plateau led to the accumulation of abundant secondary metabolites in hulless highland barley. The phytosterol level in barley oil from different areas was 1.20 9.60 g/100 g oil, higher than that of most rice bran oil 1.50-3.50 g/100 g oil 1, 2. Moreau reported that the total tocotrienol content in barley oil reached up to 0.29-0.61 g/100 g oil 3 , higher than that of the rice bran oil 0.077 g/100 g oil and the wheat brain oil 0.19 g/100 g oil 2. It has been reported that tocotrienol in barley oil is mainly α-tocotrienol, whose bioavailability is higher than γ-tocotrienol, while the tocotrienol in palm oil is mainly γ-tocotrienol 4, 5. Barley germ oil has been tested to be rich in tocopherols 6. As a byproduct of highland barley processing, highland barley bran is rich in minerals, oil, protein, polyphenols, β-glucan, oryzanol and phytosterols. However, highland barley bran is now mainly used as feed. Nowadays, highland barley bran has been incorporated into bread, cookies, and crackers making. The results showed that barley bran could effectively enhance the health-salutary components

“…Peanut being an allotetraploid crop contains two sets of alleles of any gene in its A and B genomes, and mutation in both ahFAD2A and ahFAD2B allele is required for the expression of HO trait in peanut line (Nawade et al 2018). The understanding of the genetics and molecular basis of ahFAD2 gene has led to the development of several molecular marker systems such as CAPS and allele-specific PCR (AS-PCR) assays for the accurate genotyping of ahFAD2 genes.…”

“…Apart from oil, it is also widely used for the production of snack products, peanut butter, desserts, and soups (Patil et al 2018). The nutritional quality, shelf life, and flavor of peanut oil and its products are reliant on the presence of different proportions of saturated fatty acids (SFAs), monounsaturated FA (MUFA), and poly UFA (PUFA) (Derbyshire 2014;Nawade et al 2018). Peanut oil contains nearly 11 different FAs, of which oleic acid (C18:1, Δ9), a MUFA and linoleic acid (C18:2, Δ9, Δ12), a PUFA contribute approximately 80% of the total oil composition (Nawade et al 2018).…”

“…The first HO cultivar, SunOleic95R was released in the USA using the conventional breeding method (Gorbet and Knauft 1997). Since then, over 90 HO peanut cultivars have been developed, of which the majority were bred through traditional methods and some using the chemically induced mutagenesis approach (Nawade et al 2018). Further, only a few cultivars were developed through the MAS approach namely, Tifguard High O/L (Chu et al 2011), SA Juweel and ARC Oleic2 (Mienie and Pretorius 2013).…”

Peanut is one of the most important oilseed crops grown worldwide. In this study, the mutant ahFAD2 alleles conferring high oleic (HO) content are introgressed into an elite Indian cultivar GPBD4 which is also resistant to the foliar fungal diseases like rust and late leaf spot (LLS). The allele-specific PCR (AS-PCR) and cleaved amplified polymorphic sequences (CAPS) assays were used for the marker-assisted backcross (MABC) approach and 64 HO introgression lines (ILs) were generated. These ILs were tested for the FA compositions under the glasshouse and field conditions. The oleic acid and linoleic acid contents in the ILs were recorded to be between 68.94-82.33% and 1.74-10.87%, respectively, under glasshouse and 67.04-81.71% and 2.00-15.66%, respectively, under field conditions. The increase in the oleic acid content of the ILs over its recurrent parent (RP) was recorded to the tune of 28.78-53.80% and 33.70-62.96% under glasshouse and field conditions, respectively, indicating the stable expression of ahFAD2B gene in two different environments. On the contrary, linoleic acid showed 56.47-93.03% and 40.02-92.34% reduction in the ILs over its RP under glasshouse and field conditions, respectively. These ILs with a healthy FA profile can meet not only the nutritional requirements of a health-conscious society but also the industrial demands for better shelf life of oil and its products.

“…Consequently, marker assisted selection is routinely implemented to pyramid the high O/L trait with other traits of interests (Chu et al, 2011). Other peanut producing countries such as India, China, Brazil, Argentina, South Africa, Israel, Japan and Australia are also including the high O/L trait in their peanut (Janila et al, 2016b;Nawade et al, 2018). However, information on studies of oil and other seed composition traits from West African lines is seldom available.…”

The peanut CSSL population represents one of the ways that interspecific hybridization has been used to introduce genetic variation into cultivated peanut. The lines were developed by crossing Fleur 11, a farmer preferred spanish cultivar from West Africa with a synthetic allotetraploid. The latter was developed by crossing A. duranensis to A. ipaensis and tetraploidizing the resultant hybrid. Subsequent selection with genetic markers resulted in a population comprising lines with small chromosome segments from the wild in a cultivated peanut background. The objective of this study was to characterize the protein, total oil, fatty acid and sugar profiles of the population. The results indicated that the values of Fleur 11 for all the traits analyzed were within the normal range expected in peanut. Since the population had a uniform genetic background derived from Fleur 11, the profiles for a majority of the lines were comparable to Fleur 11. However, three lines (CSSL 84, CSSL 100 and CSSL 111) were found to have elevated oleic acid and reduced linoleic and palmitic acid relative to Fleur 11. The oleic to linoleic acid ratios (O/L) for these lines were 118, 104 and 97% greater than that of Fleur 11, respectively. While the increased values are still considered to be within the normal oleic acid range, the effect of introgressions on these lines represent the possibility of discovering new sources of high O/L polymorphisms. Such polymorphisms have the potential for use in further improving peanut oil quality.
