Pelargonium Pachafred Uniform Mounded Habit Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Ivy Geranium cultivars lack uniformity and vigor in plant habit, with variations in flower size and color, and do not consistently exhibit desirable traits across different environmental conditions.
Innovation Solution
A new cultivar, 'Pachafred', resulting from a breeding program, exhibits a uniformly mounded and cascading plant habit, vigorous growth, basal branching, and bright red flowers positioned above the foliar plane, achieved through vegetative terminal cuttings and selection from a cross-pollination of proprietary Pelargonium peltatum selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing Ivy Geranium cultivars are used, then variety and diversity are maintained, but uniformity and vigor in plant habit are insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific growth habit parameters (mounded, cascading, trailing) to achieve uniformity. The breeding program focused on modifying plant architecture parameters to produce the desired uniform mounded and cascading habit while maintaining genetic diversity through controlled cross-pollination of proprietary selections.
2Reliability
If existing Ivy Geranium cultivars are used, then established varieties are available, but consistent performance under varying environmental conditions is not achieved
Solution Approach 1:
The breeding program employed feedback mechanisms by evaluating progeny under controlled greenhouse conditions and selecting plants that demonstrated consistent desirable traits. The inventor assessed uniformity, vigor, and habit characteristics across multiple generations, using this feedback to refine the breeding selection and achieve reliable performance consistency.
Solution Approach 2:
The patent achieves reliable performance by stabilizing key growth parameters through breeding. The selected cultivar exhibits consistent parameters for plant habit (mounded, cascading), flowering (freely flowering), and growth vigor that remain stable across environmental variations, as demonstrated by asexual reproduction through vegetative terminal cuttings.
3Manufacturing precision
If variability in flower size and color is present, then natural diversity is maintained, but uniformity and attractiveness are reduced
Solution Approach 1:
The patent applies local quality by selecting for specific flower characteristics (bright red color, single-type flowers positioned above and beyond the foliar plane) while maintaining genetic diversity in other aspects. The breeding program focused uniformity selection on flower color, size, and positioning as key local qualities that define the cultivar's attractiveness.
