Dallas

Engineering Aesthetics of Late Blooming

The 'Dallas' tulip is a selection product engineered for late cutting and forcing cycles. Its key feature is the fringed petal edge, a result of specific genetic expression that creates needle-like outgrowths around the perianth. For the agronomist, this implies not just aesthetics, but a necessity for microclimate control: high humidity in the bud zone with this structure increases the risk of fungal pathogens settling in the micro-cavities of the fringe.

Phytosanitary Resistance Profile

Unlike many decorative varieties that require constant fungicidal pressure, 'Dallas' demonstrates genetic resistance to a range of aggressive pathogens. Breeding efforts focused on strengthening the plant’s vascular system:

• Disease Tolerance: The cultivar exhibits high tolerance to Phomopsis and Phoma, diseases that frequently plague bulbous plants when soil aeration protocols are compromised.
• Rust and Downy Mildew Protection: The dense structure of the leaf cuticle hinders spore penetration, significantly reducing the need for prophylactic spraying in open-field conditions.

Developmental Metrics

This variety belongs to the medium-height group, making it ideal for dense planting schemes. The moderate stem height provides sufficient mechanical strength to withstand heavy buds against wind loads. The intense red pigment of the petals is highly resistant to photodegradation (fading), which is critical for maintaining market quality when harvesting late-season crops.
