Abstract

In the peanut, Arachis hypogaea L., the purpie and purpie-striped testa colors were found to be monogenicaily and digenically inherited, respectively. Incomplete dominance was observed for the solid purple color. An interaction of incomplete and complete dominance also was observed for the purple-stripe appearance. However, when either loci are homozygous recessive, stripes are not expressed. Linkage was not detected between these two testa characteristics. Gene symbols, Vsp1 and Vsp2, are suggested for the variegated purple-striped alleles.
