Petunia Duepotpi11 Compact Mounding Habit Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact Petunia plants with unique and attractive flowers that offer improved compactness, branching, and flowering habits, as existing cultivars may lack these desirable traits or exhibit variability under different environmental conditions.
Innovation Solution
A new cultivar of Petunia×hybrida, 'Duepotpi11', was developed through controlled cross-pollination, exhibiting a compact, mounding, and freely branching habit with large pink-colored flowers, which are stable and reproduce true to type through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Petunia cultivars are used, then they may have larger flower size or different colors, but they lack compactness and desirable branching habits
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific growth habit parameters (compactness, branching density, internode length) while maintaining flower size parameters. The new cultivar 'Duepotpi11' exhibits altered plant architecture parameters including reduced internode length and increased lateral branching, achieving compactness without sacrificing flower size.
2Reliability
If existing Petunia cultivars are used, then they may produce flowers, but they lack stable and consistent performance across varying environmental conditions
Solution Approach 1:
The patent employs feedback mechanisms through controlled breeding programs where plants are evaluated for consistent performance across multiple generations. The selection process monitors and selects for stable expression of compact growth habit and flowering characteristics, ensuring reliability when propagated asexually through cuttings.
3Shape
If existing Petunia cultivars are used, then they may have vigorous growth, but they lack the desired mounding and outwardly spreading habit
Solution Approach 1:
The patent applies local quality by directing growth vigor into specific architectural patterns. The cultivar exhibits localized growth characteristics where lateral branches are encouraged to develop outwardly and downward, creating a mounding habit, while maintaining overall vigorous growth through controlled apical dominance and lateral bud development.
