Inheritance of Dominant White Peanut Testa Color

Abstract

Dominant white testa color was recently found in the cultivated peanut (Arachis hypogaea L.). This white-seeded germ plasm line (PI 408735) was test-crossed with the tan-colored Krinkle-leaf genotype and the Tennessee Red and Makulu Red cultivars. The results in the F₁, F₂, and F₃ progeny indicate that the dominant white testa color of PI 408735 is simply inherited. The gene symbol Wh is proposed for this unusual peanut characteristic.
