Fort Trailing White Petunia Cultivar Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Petunia cultivars with early and freely flowering habits and unique, attractive flower colors, as existing cultivars may not meet these criteria effectively.
Innovation Solution
The development of the 'Fort Trailing White' Petunia cultivar, a naturally occurring mutation of Petunia×hybrida, characterized by an outwardly spreading and freely branching growth habit, large white-colored flowers, and good garden performance, achieved through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a planned breeding program is conducted to create new Petunia cultivars, then unique and attractive flower colors and freely-branching habits are achieved, but the complexity of the breeding process increases
Solution Approach 1:
The breeding program utilizes naturally occurring mutations that arise spontaneously in the plant population. The mutant plant with white flowers was discovered among a population of lavender-flowered plants, requiring no artificial intervention to generate the variation. The plant self-selected the desirable trait through natural mutation, and the breeder simply needed to identify and propagate it.
Solution Approach 2:
The invention exploits a natural parameter change (flower color mutation from lavender to white) that occurred spontaneously in the plant population. By selecting and propagating this naturally mutated plant through asexual reproduction, the breeder captured the parameter change without needing to induce it through complex breeding interventions.
2Stability of the object's composition
If terminal cuttings are used for asexual reproduction, then stable and true-to-type reproduction is achieved, but the time and resources for propagation increase
Solution Approach 1:
The invention extracts the desirable mutant traits (white flower color, trailing growth habit, free branching) from the parent plant through terminal cuttings. This propagation method isolates and reproduces only the essential vegetative portions needed to maintain genetic fidelity, discarding the need for seed production and germination processes.
Solution Approach 2:
The terminal cuttings are prepared and propagated in advance to establish stable stock plants before commercial production. This preliminary propagation ensures that the genetic traits are locked in early, allowing for efficient mass production later without risking trait variation.
