Two New Cultivars of Pothos (Epipremnum aureum)
Year: 2025
Type: article
Abstract: Epipremnum Schott, commonly known as pothos, is a member of the family Araceae and is indigenous to Southeast Asia and the Solomon Islands (Henny and Chen 2003). The genus has ∼10 known species (Bailey and Bailey 1976). Still, only Epipremnum aureum and Epipremnum pinnatum ‘Aureum’ (Boyce 1998) have been produced commercially. Pothos is one of the most popular foliage plants worldwide (Chen 2024). It usually does not flower in nature (Chen et al. 2002) because transcripts for the biosynthesis of gibberellic acid (GA), EaGA3ox1, and the GA-responsive floral meristem gene, EaLFY, are inactive in pothos (Hung et al. 2016). As a result, breeding through hybridization has not been reported. However, we developed a method for inducing pothos flowering by foliar spray of GA3 (Hung et al. 2016). Following GA3 treatment, blooms were induced, and self-pollination of ‘Marble Queen’ was achieved. ‘UF-Ea-0310’ was selected from self-pollinated seedling populations of ‘Marble Queen’. Regeneration of ‘UF-Ea-0310’ via direct somatic embryogenesis resulted in the isolation of a complete green-leaved cultivar: UF-Ea-0314.
