Petunia Cultivar Selection for Dense Branching and Garden Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct cultivar of Petunia X hybrida that exhibits unique characteristics such as upright to spreading plant habit, vigorous growth, dense branching, and deep purplish pink flowers, which are not adequately addressed by existing Petunia varieties.
Innovation Solution
The development of a new Petunia cultivar, 'WNPETSVBG27', which is a naturally-occurring mutation of 'USTUNI6001', characterized by its upright to spreading growth habit, dense branching, and deep purplish pink flowers, achieved through asexual reproduction by vegetative terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new Petunia cultivar is developed with unique characteristics, then distinctiveness and garden performance are improved, but breeding complexity and time requirements increase
Solution Approach 1:
The patent applies parameter changes by selecting for specific phenotypic parameters including deep purplish pink flower color, upright to spreading plant habit, dense branching, and darker green leaves. These parameter selections create a distinct cultivar with improved garden performance while managing breeding complexity through focused selection criteria.
2Reliability
If a new Petunia cultivar is developed with unique characteristics, then distinctiveness is improved, but time to develop and stabilize the cultivar increases
Solution Approach 1:
The patent applies preliminary action through the discovery and selection of a naturally-occurring mutation from an existing population. By identifying and propagating the mutant plant that already possesses the desired traits, the breeding process is accelerated compared to creating these traits through conventional cross-breeding methods.
3Stability of the object's composition
If Petunia plants are propagated by vegetative terminal cuttings, then genetic stability and true-to-type reproduction are improved, but propagation time and labor requirements increase
Solution Approach 1:
The patent applies copying through vegetative propagation by terminal cuttings, where new plants are created as genetic copies of the selected mutant parent. This method ensures true-to-type reproduction and genetic stability, maintaining the distinctive traits of the new cultivar across generations while providing an efficient propagation system.
