Lotus (Nelumbo Adans.) is one of the earliest angiosperms (Du et al., 2016) and comprises only two species, Nelumbo nucifera Gaertn. and Nelumbo lutea (Willd.) Pers, which are herbaceous aquatic perennials that are valued as ornamental plants, especially in landscaping. Nelumbo nucifera is largely distributed throughout Asia and Oceania, with the natural distribution center in China, whereas N. lutea is distributed in North America (Wang and Zhang, 2004; Zhang et al., 2011). In China, N. nucifera has been cultivated for ≈3000 years resulting in a diversity of floral forms that include single, semidouble, double, duplicate-layered, and thousand-petaled, and flower colors that include white, pink, and red because of the lack of a yellow genotype (Liu et al., 2017). Nelumbo nucifera contrasts with forms of N. lutea that are typically characterized by yellow, single flowers with fewer than 20 petals. The creation of interspecific hybrids between the two Nelumbo species has been a longstanding goal for plant breeders and, following several years of breeding from the female parent lotus, ‘Friendship Peony’, we have bred a duplicate-layered, yellow-flowered hybrid, named ‘Jin Dieyu’ (Figs. 1 and 2). Here, we describe the breeding process and characters of ‘Jin Dieyu’, and provide recommendations for its cultivation.
