Double-flowered vinca [Catharanthus roseus (L.) G. Don] TYV1 (female parent) was crossed with single-flowered TYV3 and TYV4 (male parent) and single-flowered F1 generation was obtained. Fifteen F1 plants with large flower and vigorous growth from both combinations were selected. Double-flowered F2 plants were obtained following self-pollinated of these 15 F1 plants. Five double-flowered lines were selected and named as ‘Taoyuan No.1-Rose Girl’, ‘Taoyuan No.2-Peach Lady’, ‘Taoyuan No.3-Red Butterfly’, ‘Taoyuan No.4-Summer Snow’, and ‘Taoyuan No.5-Red Lady’ after one selection and two cultivars comparison tests. New double-flowered vinca cultivars have branching and multi-blooming habit, and are compaect suitable for potted flowers. Double-flowered vinca have two layers of petal, funnel-shaped flower, and 3.3 ± 0.3 cm flower diameters. The five selected cultivars are the first reported for doube-flowered vinca with plant breeders’ right.
