“…In sunflower, reports are on additive gene effect for palmitoleic acid inheritance (41). In contrast to our results of saturated fatty acids, only additive gene effect for saturated fatty acids were also reported such as myristic acid (22), plamitic acid (42,43) and arachidic acid (43,44).…”

Development of a variety having high oil content and desirable fatty acid compositions is a major objective of groundnut (Arachis hypogaea L.) breeding programmes. To study the gene action (through combining ability) and heterosis for oil and fatty acids, an experiment was conducted using a 4 × 4 full diallel method. Four parents and their 12 F1 hybrids were evaluated following a randomized complete block design. Data were recorded for oil, fatty acids and oleic-linolenic (O/L) acid ratio. Highly significant genotypic variation was found among the parents and their F1 hybrids for the studied traits. The combining ability studies (general, specific and reciprocal) reflected that the oil and fatty acid traits were controlled by both non-additive and additive genes having significant maternal effects. Results also revealed that the parent China Badam was the best general combiner for oil, linolenic acid and O/L ratio whereas the parent Binachinabadam-4 for oleic and linoleic acids. Best SCA performance was found from the cross Dacca-1 × China Badam and Binachinabadam-4 × China Badam for oil, oleic- and linolenic-acid contents. Significant heterosis for oil content was observed in F1 hybrids obtained from the cross Binachinabadam-4 × China Badam and its reciprocal cross. The cross China Badam × GC (24)-1-1-1 showed a higher O/L ratio (>4) along with lower level of saturated fatty acids. Therefore, these crosses could be exploited in future breeding programmes to develop new lines for higher oil and healthy fatty acid compositions.

“…Oleic (C18.1) as the major unsaturated FA varied from 39.71 to 55.89%. This finding is close to the data reported by Khetarpaul, Jood, & Goyal (2007) Achola et al (2017) who reported a range of 14.61 to 18.6% palmitic acid (C16.0) in Serenuts 5 to 10. Shahidi (2005) and Özcan (2010) presented slightly lower ranges of 8 to14% and 7.63 to 11.41% palmitic acid (C16.0), respectively, in groundnut oil.…”

This study determined the fatty acid (FA) composition of oil from groundnuts and oyster nuts in Uganda. The FA composition was determined by Gas Chromatography/Mass Spectrometry with FID. Oil from groundnuts contained 39.71 to 55.89% oleic, 20.21 to 35.59% linoleic and 11.91 to 17.16% palmitic acids. Oil from Serenut cultivars contained cis 11-eicosenoic acid (C20.1), cis 11, 14 eicosadienoic acid (C20.2) and cis 11, 14, 17 eicosatrienoic acid (C20.3ω3) which were not detected in traditional cultivars. Oyster nut oil was high in linoleic acid at 41.02 to 44.86% and palmitic acid at 33.58 to 38.11% while oleic acid was low with amounts <10%. The polyunsaturated to saturated FA ratios of oil from groundnuts and oyster nuts were >0.45, the minimum recommended by FAO. The atherogenic (AI) and thrombogenic indices (TI) of <1 and the hypocholesterolemic to hypercholesterolemic index (h/H) of >4 in groundnut oil were favorable for cardiovascular health. Indices for oyster nut oil were ≤1for AI and >1for TI. The h/H was low compared to that of groundnut oil. Results showed little distinction between the FA compositions of oil from traditional and improved groundnuts suggesting that breeding may not have significant effect on major FAs. Oyster nut oil contained saturated and unsaturated FA in a ratio of 1:1. The lipid health indices for groundnut oil were within recommendations while those of oyster nuts were less desirable. Oyster nut oil should therefore be consumed with moderation.

“…All the test genotypes that recorded higher OAC under both conditions showed lower LAC (<13%). Low oleic/linoleic ratio enhances the stability and shelf-life of groundnut oil and other groundnut derived products (Achola et al, 2017 Comparison across subspecies for KY and HY, and quality traits revealed the Virginia bunch (subspecies hypogaea) recorded slightly higher values for several traits including OC, OAC, HY, DM, NC, ADFDM, and ADLDM (Figure 1). These allowed identification of genotypes with desirable kernel quality, HY, and fodder quality.…”

The objective of this study was to determine drought tolerance, kernel (KY) and fodder yield and quality amongst diverse groundnut genotypes for direct production or breeding. Hundred genotypes were evaluated at ICRISAT, India during 2018–2019 and 2019–2020 under drought‐stressed (DS) and nonstressed (NS) conditions. Data were collected on KY; oil content (OC); oil yield (OY); protein content; palmitic, stearic, oleic, and linoleic acid contents; haulm yield (HY); and fodder quality parameters such as the contents of dry matter, ash, nitrogen (NC), neutral detergent fiber (NDFDM), acid detergent fiber (ADFDM), acid detergent lignin (ADLDM), in vitro digestibility, and metabolizable energy. Data were subjected to parametric and nonparametric statistical analyses. Combined analysis of variance revealed significant (P < .05) genotype differences for all assessed traits. Genotype × water regime interaction effects were significant for KY, OC, ash, NC, NDFDM, and ADLDM. Kernel yield positively and significantly (P < .05) correlated with OY (r = .99), LAC (r = .13), ash (r = .32), and NDFDM (r = .54) under DS condition. Haulm yield was positively and significantly (P < .05) correlated with OC (r = .24), NDFDM (r = .19), ADFDM (r = .18), and ADLDM (r = .17) under DS condition. The study identified four genotypes with high kernel and haulm yields, and six genotypes with high oleic acid content. Further, 10 genotypes were selected with relatively better drought tolerance. The selected genotypes are recommended for further breeding and variety release adapted to drought conditions.
