Nutrient Amounts

The cultivated peanut (Arachis hypogaea L.) is one of the most widely consumed legumes globally due to its nutrient content, taste, and affordability. Nutrient composition and consumer preference were determined for twenty local farmer (landrace) and commercial peanut varieties grown in the Nakaseke and Nakasongola districts of the central wooded savanna of Uganda through sensory and laboratory evaluation. Significant differences in nutrient content (p < 0.05) among peanut varieties were found within and across sites. A significant relationship between nutrient content and consumer preference for varieties within and across sites was also realized (Wilk’s lambda = 0.05, p = 0.00). The differences in nutrient content influenced key organoleptic characteristics, including taste, crunchiness, appearance, and soup aroma, which contributed to why consumers may prefer certain varieties to others. Gender differences in variety selection were significantly related to consumer preference for the crunchiness of roasted peanut varieties (F = 5.7, p = 0.016). The results imply that selecting different varieties of peanuts enables consumers to receive different nutrient amounts, while experiencing variety uniqueness. The promotion of peanut intraspecific diversity is crucial for improved nutrition, organoleptic appreciation and the livelihood of those engaged in peanut value chains, especially for the actors who specialize in different peanut products. The conservation of peanut diversity will ensure that the present and future generations benefit from the nutritional content and organoleptic enjoyment that is linked to unique peanut varieties.

Abstract A better understanding of peanut (Arachis hypogaea L.) testa color genetics would be helpful to breeders in developing new cultivars to meet U.S. market acceptability. Wine is one of the least understood of all basic testa colors in peanut. The objective of this genetic study was to gain further knowledge on the inheritance of wine testa color and possible allelic interactions. Crosses were made using two true-breeding wine testa color genotypes (Wine-Frr and PI 264549) as females with the tan testa and recessive red testa male parents Krinkle-Leaf and Makulu Red, respectively. F1, F2, and F3 data suggest no difference between the two wine testa color genotypes. Inheritance of wine testa color was found to be recessive with a one gene difference between wine and the tan testa color of Krinkle-Leaf, and with two gene differences between wine and the recessive red testa color of Makulu Red. Inheritance of wine seems to closely parallel that for recessive red testa color in the cultivated peanut.
