Petunia Dueswebuce Cultivar Stability and Compactness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new trailing Petunia plants with unique and attractive flowers that exhibit stable and reproducible traits across varying environmental conditions and cultural practices, as existing cultivars may show variance in flower color and compactness.
Innovation Solution
The development of a new Petunia×hybrida cultivar, 'DUESWEBUCE', resulting from a cross-pollination between proprietary selections T01-0009-004 and T06-2126-003, characterized by a mounding and spreading habit, freely branching, early and continuous flowering, large light violet-colored flowers with purple venation, and good garden performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Petunia cultivars are used, then they may have simple growth habits, but they show variance in flower color and compactness across different environmental conditions
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar with specific genetic parameters that stabilize flower color intensity and plant compactness across varying environmental conditions. The cross-breeding program selected for specific trait parameters including vibrant flower color, compact growth habit, and consistent flowering performance that remain stable regardless of environmental variations.
2Shape
If new trailing Petunia plants with unique flowers are developed, then flower attractiveness is improved, but maintaining stable and reproducible traits across environmental conditions becomes more difficult
Solution Approach 1:
The patent applies preliminary action through extensive pre-breeding selection and controlled cross-pollination programs that establish stable genetic foundations before releasing the cultivar. The breeding program conducted preliminary selections for compactness, flower color intensity, and branching patterns, ensuring these traits are genetically locked in before field testing across multiple environments and generations.
Solution Approach 2:
The patent applies feedback mechanisms through multi-generation testing and evaluation where the new cultivar's performance is continuously monitored across different environmental conditions. The breeding program uses feedback from field trials, greenhouse tests, and comparative evaluations against parent plants to confirm trait stability and make selective breeding adjustments to enhance consistency of flower color and compactness.
3Area of moving object
If Petunia plants with larger and more vibrant flowers are created, then flower attractiveness increases, but plant compactness may be reduced
Solution Approach 1:
The patent applies local quality by concentrating genetic expression of large, vibrant flowers specifically in the floral structures while maintaining compact growth habits in the vegetative portions of the plant. The cross-breeding program selected for localized traits where flower size and color intensity are enhanced without proportionally increasing overall plant volume, achieving vibrant 6cm diameter flowers on a compact trailing framework.
