Lavender Petunia Cultivar from a Natural Branch Mutation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Petunia X hybrida that exhibits unique characteristics such as upright to outwardly spreading plant habit, vigorous growth, dense and bushy form, early and continuous flowering, and lavender-colored flowers with lighter throats, which differ from existing varieties in terms of flower color and leaf shape.
Innovation Solution
The development of a new Petunia cultivar, 'WNPETSVCJ26', which is a naturally-occurring branch mutation of 'WNPESVJAZ', characterized by its stable asexual reproduction through vegetative terminal cuttings, displaying traits like lavender flowers, lighter lavender throats, narrower leaves, and excellent container and garden performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new Petunia cultivar is developed with unique characteristics (lavender flowers, lighter throats, narrower leaves), then ornamental value and adaptability are improved, but breeding complexity and selection difficulty increase
Solution Approach 1:
The patent utilizes a naturally-occurring branch mutation that spontaneously arose in the parent cultivar 'WNPESVJAZ'. This self-service approach allows the new cultivar 'WNPETSVCJ26' to develop unique characteristics (lavender flowers, lighter throats, narrower leaves) without requiring complex external breeding interventions, thereby improving adaptability while minimizing breeding complexity
Solution Approach 2:
The patent captures a naturally occurring mutation that changed specific parameters of the parent plant (flower color to lavender, throat color to lighter lavender, leaf width to narrower). This parameter change approach allows the new cultivar to exhibit improved ornamental value and adaptability through natural genetic variation rather than complex breeding programs
2Productivity
If the plant exhibits vigorous growth and rapid growth rate, then productivity and ornamental value are improved, but control over plant size and shape becomes more difficult
Solution Approach 1:
The patent describes a plant habit that is dynamic in nature - upright to outwardly spreading to mounding to eventually trailing. This dynamic growth pattern allows the plant to adapt its form based on growing conditions and container size, providing both vigorous growth and a degree of self-regulation that eases control over plant size and shape
3Adaptability or versatility
If the plant has freely branching habit and dense bushy form, then ornamental value is improved, but complexity of plant structure increases
Solution Approach 1:
The patent describes a freely branching habit with dense bushy form, which segments the plant into multiple branches and growth points. This segmentation creates a complex but organized structure that maximizes ornamental value through increased flowering sites and dense foliage, while the repetitive branching pattern follows natural growth rules that simplify cultivation management
