Flower color — Argyranthemum frutescens

Argyranthemum frutescens (L.) Sch. Bip.

Color is a key morphological trait in the variety testing of Argyranthemum, evaluated on the upper side of the ray florets using the RHS Colour Chart.

In the reference 8 varieties crop Marguerite daisy, where this is mentioned in the description.

The assessment of ray floret color in Argyranthemum frutescens is carried out visually in accordance with UPOV protocols (TG/222). Experts record the color of the petals and buds, comparing the observed shade against the reference RHS Colour Charts to ensure objectivity when describing varietal characteristics.

The trait is classified into five main groups: white, yellow, pink, red, and purple, with cream and apricot shades also being distinguished. Additionally, the intensity of the tone is evaluated, which is critical for variety identification during the Distinctness, Uniformity, and Stability (DUS) examination.

In the agronomy of ornamental crops, color stability is an important quality indicator, as it determines the plant's market value. Stability is manifested in the pigment's resistance to sun-fading and temperature fluctuations, which requires breeders to strictly select for stable lines.
