Quality and flavor of edible peanuts and its products are affected by fatty acid composition of oil. The information related to chemical composition of Peanut grown in the country are scarce, therefore, the present investigation was designed to determine the oil and fatty acid composition of some commonly grown peanut cultivars in Pakistan. Seven Peanut cultivars were grown during 2008 in randomized complete block design replicated thrice. The tested cultivars differed significantly for oil content which ranged from 49.83 to 53.06% on dry weight basis, thus showing differences of 7% among cultivars. The saturated fatty acids (Palmatic & Stearic acid) in different cultivars ranged between 9.95 to 10.79% and 1.63 to 2.19%, respectively. Differences among cultivars for oleic acid exhibited significance which ranged between 49.34 to 54.83%. Similarly, cultivars differed statistically for linoleic acid which showed a range of 28.99 to 34.23%, thus depicted difference of 7%. Significant differences among tested cultivars may be attributed to the place of origin of particular cultivar. An inverse relationship was exhibited between oleic and linoleic acid, similar to other edible oils.

    ABSTRACT: Eight peanut (Arachis hypogaea) cultivars that were grown in Mexico were analyzed for the physical and chemical characteristics of their seeds and for the physicochemical properties and fatty acid profiles of their oils to select the most promising candidate in terms of oil stability and nutrient composition. The results showed that the protein ranged from 28.5% to 32.9% and the oil varied from 37.9% to 56.3%. The major fatty acids found in the oil samples were palmitic (11.9–13.2%), oleic (45.2–53.8%) and linoleic (25.1–29.2%) acids. The oleic/linoleic ratio was between 1.8 and 2.1. The physicochemical characteristics under evaluation were as follows: the iodine value (88.6–105.4), saponification value (142.5–181.8) and acidity (1.1–2.5%). Ranferi Díaz was the variety that presented higher stability and greater health benefits. This variety would be a good choice for agronomic purposes and genetic breeding programs.

    ABSTRACT: Iron deficiency is one of the major yield limiting factors in groundnut. The soils of Pothwar (90% of groundnut production area in Pakistan) are calcareous in nature, thus groundnut is exposed to Fe deficiency. Seeds of 20 varieties/ advance breeding lines of groundnut were collected to evaluate Fe deficiency responses. Seeds were germinated in pots with 1:1 soil to sand ratio with added recommended NPK fertilizer. Fe-EDTA (0.1mmol/L) was supplemented as foliar spray to control plants, however, no additional Fe was applied to Fe deficient plants. Physiological parameters such as chlorophyll content, active and total Fe concentrations were recorded for each genotype under Fe deficient and Fe sufficient conditions. Morphological parameters including pods per plant, pod weight per plant, seeds per plant and seed weight per plant were recorded at harvesting. Genotypes were ranked by multivariate cluster analysis. Data showed that BARI-2000 and Chakori were among the Fe stress tolerant genotypes while Golden and Lisn were among the Fe deficiency intolerant genotypes. Relative values for SPAD values ranged from 60.50% in 2KCG020 to 87. 8% in BARI-2000. Total Fe concentration was 48.8%in Lisn and 66.5% in BARI-2000. Relative value of biomass produced by Chakori and Golden was 85.5% and 66.3%, respectively. The genotypes ranked best on the basis of morpho-physiological parameters will be helpful for making recommendations to groundnut farmers of the Pothwar region.

    ABSTRACT: In spite of the importance of parental inheritance effects, many aspects remain inadequately explained. The objective of this study was to explore parental effects on their progeny by estimating the variability of nutritional content in peanut seeds. The peanut cv. Boreom 1 was derived from Suwon 108 (female) and Milyang 4 (male). Protein and amino acid analyses revealed that male and female parent influences on protein, Asp, Thr, Ser, Glu, Pro, Ala, Cys, Val, Met, Ile, Leu, Tyr, Phe, His, and Arg content in their progeny. The oil and fatty acid composition (C16:0, C18:0, C18:1, C18:2, C20:0, C20:1, and C22:0) of the progeny were controlled by both parental types. The synergistic interaction of female and male parental genes was also shown on sucrose and stachiyose content, while paternal effect was found on raffinose in their progeny. The antioxidant activity, daidzin, glycitin, genistin, mal-glycitin, maldaidzin, mal-genistin, and daidzein content of Boreom 1 were significantly correlated with those secondary metabolites of female parent. Our results documented that both parental genes differentially influenced on nutritional composition of their progeny, Boreom 1. This biochemical evidence of parental effects would be support to identify the suitable cultivars to improve the crop breeding.
