Abstract Undesirably low oleic acid and high linoleic acid concentrations in seed oil are typical of Valencia peanuts (Arachis hypogaea L.) produced in a cool, short-season climate. Improved oil quality may be achieved by incorporating Virginia type germplasm into adapted Valencia peanuts. The objectives of this study were to determine the oil quality of nine Valencia and four Virginia peanut lines, evaluate their combining ability for oil concentration, fatty acid composition of the oil, and several taxonomic characters, and assess the potential for developing cultivars adapted to Ontario with improved oil quality. General combining ability (GCA) of the Virginia parents significantly exceeded specific combining ability (SCA) for all fatty acids except arachidic, and also for oleic/linoleic (O/L) ratio, days to first flowering, days to full flowering, and branching pattern (R/R + V ratio). GCA of the Valencia parents significantly exceeded SCA only for oil concentration. Significant SCA estimates were found for oil concentration, palmitic and oleic acids, O/L ratio, and height of the main axis (first date). Significant heterosis was detected for all taxonomic characters except days to first flowering. Genetic variability for all characters except arachidic acid indicates that the development of Ontario cultivars with improved oil quality, in terms of higher oil content and reduced linoleic acid levels, appears feasible through breeding efforts.

Abstract The quality of edible oils is now receiving increasing consideration from consumers and processors. The present study was conducted to investigate the effects of environments on oil content and fatty acid composition in peanut. The correlation between oil content and oil quality parameters was also studied. Thirteen peanut (Arachis hypogaea L.) genotypes were grown in 12 environments for the study. Soils at experiment locations differed significantly for pH, EC, and N, P, Zn, Mn, and Fe contents. Significant genotype, environment, and genotype x environment interaction effects were observed for oil content, individual fatty acid contents, and derived oil quality parameters. The original range of 34-54% of oil content based on one season/location evaluation in these lines was not repeatable, and ranged from 45-50% in multilocation evaluation. Oil content was positively correlated with soil pH and Fe content. The correlation of oleic and linoleic acid content with soil pH and Fe content was positive in the former and negative in the latter. The oil content was positively correlated with O/L ratio. Oliec and linoleic acid contents were negatively correlated. Selection for reduced linoleic acid level in genotypes would also reduce levels of total long chain saturated fatty (TLCSF) acids. Of the thirteen genotypes tested, ICG 5856, ICG 5369, and ICGV 87124 could be used in breeding for improved oil quality.

This study was conducted at the experimental area of the Cukurova University, Faculty of Agriculture in 2017, 2018 and 2019 in Adana (Mediterranean Region)-Turkey. The objective of this study was to compare of fatty acids composition and oil quality factors of different market type peanut (Arachis hypogaea L.) varieties grown as a main crop. Four different market type peanut varieties, including Virginia (Halisbey), Runner (G.Green), Spanish (Florispan) and Valencia (G.Red) were used as plant material in this research. The experimental design was a randomized complete block design with three replications. Oil content, fatty acids composition such as oleic acid, linoleic acid, stearic acid palmitic acid and oil quality factors such as Oleic/linoleic acid ratio (O/L) and iodine value (IV) of peanut seed oil were investigated. According to a three-year results; the oil content of the peanut varieties varied between 45.38% and 51.28%. The total saturated fatty acid was higher in Spanish and Valencia types than Virginia and Runner types. On the other hand, the total unsaturated fatty acid was higher in Virginia and Runner types than the others types.
