Petunia Cultivar Sunsurfpafure Stabilizing Traits Across Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Petunia cultivars lack desirable traits such as attractive foliage shape and coloration, vigorous growth, and extended flowering periods, which are not consistently achieved across varying environmental conditions.
Innovation Solution
The development of the new Petunia cultivar 'Sunsurfpafure' through controlled breeding, combining the traits of Prime Time Burgundy Star and a proprietary selection of Petunia×hybrida, resulting in a plant with a spreading to trailing habit, vigorous growth, freely branching and flowering, and medium-sized red-purple flowers with white margins, which are stable across different environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional Petunia cultivars are grown under varying environmental conditions, then their growth and flowering characteristics change, but their foliage shape, coloration, and flowering period become inconsistent and less desirable
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic parameters through controlled breeding. The cultivar 'Sunsurfpafure' was developed through systematic crossing and selection to fix desirable traits (foliage shape, coloration, flowering period) as stable genetic parameters that remain consistent across environmental variations, while allowing controlled expression of growth characteristics.
2Productivity
If Petunia cultivars are bred for vigorous growth and extended flowering periods, then productivity increases, but foliage shape and coloration attractiveness may be compromised
Solution Approach 1:
The patent merges multiple desirable traits from different parent cultivars through controlled cross-breeding. The cultivar 'Sunsurfpafure' combines the vigorous growth and extended flowering period characteristics from one parent with the attractive foliage shape and coloration from another, achieving a unified plant that expresses all desired traits simultaneously without compromise.
3Shape
If Petunia cultivars are selected for attractive foliage and extended flowering, then aesthetic value increases, but growth vigor may be reduced
Solution Approach 1:
The patent applies local quality by allowing different parts of the plant to express different characteristics optimized for their function. The foliage maintains attractive shape and coloration as selected, while the growth system expresses vigor through controlled branching patterns and root development, with each trait expressed locally where most beneficial rather than uniformly across the entire plant.
