The inheritance of testa color variegation was investigated in reciprocal crosses between the variegated (red on white) PI 274191 ✕ solid red PI 371965 peanut (Arachis hypogaea L.) genotypes. F2 phenotypic segregation was consistent with that of a genetic model for incomplete dominance at one locus, designated V. Microscopic examination showed that the V gene inhibited full cellular development of the outer red epidermal layer of the testa in certain regions. This inhibition exposed the underlying white cellular layer resulting in a variegated pattern. The homozygously recessive locus, v, does not prevent the r2 locus from producing phenotypes with solid red color testa.
