Variety traits
Phacelia tanacetifolia Benth.
Flower color of lacy phacelia (Phacelia tanacetifolia) is a qualitative morphological trait used for variety identification within the DUS system.
In the reference 4 varieties crop Lacy phacelia, where this is mentioned in the description.
Evaluation of the corolla color of lacy phacelia is performed visually in accordance with UPOV test guidelines. Within the framework of official Distinctness, Uniformity, and Stability (DUS) testing, three main color gradations are distinguished: white, blue-violet, and red-violet.
This trait is a qualitative characteristic and serves as a breeding marker for distinguishing between varieties. Research indicates that the choice of a phenotypic variant based on petal color may correlate with plant architectural features, such as shoot length; however, no direct dependence between color and nectar productivity or the timing of phenological phases has been established.
