Abstract
Selection M0107-4 is a new Mentha piperita plant that has more resistance to Verticillium wilt and mint rust than existing peppermint varieties. The essential oil produced by this plant resembles typical peppermint oil in component composition, but differs in the typical ratio of components. The oil is milder than typical peppermint oil organoleptically because it has a lower Menthol and higher Menthone content. The plant starts growth early in the spring, has vigorous growth until flowering and matures later than Mitcham type peppermint.
