Roelina

Engineering Parameters of the Roelina Variety

The Roelina tulip belongs to the Triumph class, the most sought-after segment for professional greenhouse forcing and landscape architecture. The technical value of this variety lies in the precise balance between vegetative biomass and decorative quality. Its medium height provides optimal resistance to lodging, which is a critical factor for maintaining high-density planting efficiency in professional growing facilities.

Phytosanitary Profile

Roelina’s breeding program focuses on enhancing resistance to key bulb pathogens. During field trials, the variety demonstrated robust immunity to the following infectious agents:

• Sclerotinia (Sclerotinia bulborum): genetic resistance significantly reduces the risk of planting material loss during drainage fluctuations.
• Downy Mildew (Peronospora): a dense leaf cuticle inhibits mycelial penetration even in high-humidity conditions.
• Phomopsis and Phoma: enhanced protection against these fungal diseases allows for reduced fungicide applications, thereby lowering overall production costs.

Flowering Architecture

This mid-season hybrid features snow-white petals with high light reflectance, making it a preferred choice for high-end floral arrangements. The goblet shape is classic for the Triumph class, characterized by tightly adhering petals that maintain their structure under temperature fluctuations. The optimal plant height makes Roelina suitable for both commercial cut flower production and professional landscaping.
