Flower color — Mandevilla sanderi

Mandevilla sanderi (Hemsl.) Woodson

Flower color is a key morphological descriptor of a cultivar, determined by the presence of pelargonidin and cyanidin anthocyanins. The trait is evaluated based on color intensity and the presence of secondary shades using international color charts.

In the reference 8 varieties crop Brazilian jasmine, where this is mentioned in the description.

Mandevilla sanderi is characterized by a limited palette, including shades of red, crimson, pink, and white. The presence of blue, yellow, or orange pigments is genetically impossible for this species. Color evaluation is conducted according to DUS testing protocols, where the primary color is determined by surface area, and the secondary color is recorded if present.

Color stability depends on light and temperature conditions, as well as substrate pH levels, which affect vacuolar pigments. A loss of color stability during temperature stress is considered a breeding defect. To ensure varietal consistency, it is recommended to maintain a substrate pH of approximately 5.5, which promotes optimal expression of pigment saturation.
