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.
