Petunia ‘PEHY0090’ Cultivar for Stable Red, Early Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Petunia hybrida cultivar with small flowers, medium early flowering, and a semi-trailing plant habit, which is distinct from existing varieties in terms of flower color, vigor, and flowering time.
Innovation Solution
The development of a new Petunia hybrida cultivar, named 'PEHY0090', with specific characteristics such as red flower color, semi-trailing habit, and medium early flowering, achieved through controlled hybridization and asexual reproduction, ensuring consistent trait expression across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a new Petunia hybrida cultivar is developed through hybridization to achieve distinct characteristics, then flower color, plant habit, and flowering time can be differentiated from existing varieties, but the stability and consistency of these traits across generations may be compromised
Solution Approach 1:
The patent applies preliminary action by performing controlled hybridization between specifically selected parent plants ('BB1550-21V' and 'PET20-0401-2') before asexual propagation. This preliminary genetic combination ensures that the desired traits (red flower color, semi-trailing habit, medium-early flowering) are established in the F1 generation, which are then fixed through subsequent asexual reproduction to maintain stability across generations.
Solution Approach 2:
The patent employs copying through asexual propagation methods (cuttings, tissue culture) to reproduce the selected F1 plant exactly. This copying process creates genetically identical clones that preserve the distinct characteristics achieved through hybridization, ensuring both distinctiveness from other varieties and stability across generations.
2Loss of time
If a Petunia cultivar is selected for medium early flowering, then it can fill a specific market niche, but the uniformity of flowering time across different environmental conditions may be reduced
Solution Approach 1:
The patent applies parameter changes by selecting and fixing specific genetic parameters that control flowering time through controlled hybridization. The resulting cultivar 'PEHY0090' has stabilized genetic parameters for medium-early flowering that provide consistent performance across varying environmental conditions, achieving both timely flowering and environmental adaptability.
3Shape
If a Petunia cultivar is developed with small flowers, then it can offer a distinct aesthetic appeal, but the overall visual impact and floriferousness may be reduced
Solution Approach 1:
The patent applies local quality by developing a cultivar with uniformly small flowers (2-3 cm diameter) that exhibit enhanced local characteristics including intense red coloration, well-defined veining patterns, and compact flower forms. This local quality enhancement in each individual flower compensates for the smaller size, maintaining overall visual impact through quality rather than quantity.
