Verbena 'Dueverlinre' Compact Habit Large Flower Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Verbena plant cultivars lack compact and early-flowering varieties with large, attractive flowers, and existing cultivars like 'Vepita Dark Red' have smaller flowers and different flower colors.
Innovation Solution
A new Verbena hybrida cultivar 'Dueverlinre' was developed through controlled cross-pollination, exhibiting a compact, semi-upright growth habit, freely branching, and large red flowers held above the foliage in mounded umbels, distinguishing it from its parents and other cultivars like 'Vepita Dark Red'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing Verbena cultivars are used, then they have established growth habits, but they lack compact size and early flowering with large flowers
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific traits including compact plant habit, early flowering time, and large flower size. The cultivar 'Dueverlinre' exhibits altered parameters compared to parent plants, achieving a compact mounding habit while producing large flowers that bloom early in the season.
2Area of moving object
If Verbena cultivars with large flowers are developed, then flower size increases, but plant size may become less compact
Solution Approach 1:
The patent applies local quality by concentrating floral development in a compact mounding habit. The large flowers are produced in dense clusters along the compact plant structure, creating a localized concentration of floral display area while maintaining overall plant compactness. The flowers are held above the foliage plane in umbels, maximizing visual impact within a small footprint.
3Volume of moving object
If Verbena cultivars are bred for compact habit, then plant size decreases, but flower size may be reduced
Solution Approach 1:
The patent applies preliminary action through selective breeding and propagation protocols that establish compact habit and large flower traits before commercial production. Terminal cuttings are used to propagate the cultivar, ensuring that the compact mounding habit and large flower characteristics are established early and maintained consistently across generations.
4Adaptability or versatility
If new traits are introduced through cross-pollination, then unique characteristics are created, but stability of traits across generations may be compromised
Solution Approach 1:
The patent applies self-service through true-to-type propagation using terminal cuttings. The cultivar propagates itself asexually, maintaining the unique combination of compact habit, early flowering, and large flowers without genetic variation. This self-propagation mechanism ensures trait stability while preserving the unique characteristics created through the original cross-pollination.
