Petchoa Hybrid Breeding for Large Red-Purple Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new and distinct varieties of Petunia x Calibrachoa hybrids that exhibit specific characteristics such as large, red-purple flowers and semi-upright plant habit, which are not adequately addressed by existing varieties.
Innovation Solution
A new Petunia x Calibrachoa hybrid variety, 'KLECA22835', is developed through a controlled-cross between SuperCal® Cherry Improved and 'KLECA17395', exhibiting large red-purple flowers and semi-upright plant habit, and is propagated via cuttings, ensuring reproducibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Petunia x Calibrachoa hybrid varieties are used, then general flowering characteristics are maintained, but large flower size with specific red-purple coloration and semi-upright habit are not achieved
Solution Approach 1:
The breeding program segments the desired traits by performing targeted controlled crosses between specific parent varieties (SuperCal® Cherry Improved and KLECA17395) to isolate and combine particular characteristics (large flower size, red-purple coloration, semi-upright habit) rather than relying on general hybrid characteristics
Solution Approach 2:
The invention applies local quality by selecting for specific localized traits in the hybrid offspring - particularly the red-purple flower coloration and semi-upright growth habit - while maintaining other general Petunia x Calibrachoa hybrid characteristics, creating a variety with distinctive local features
2Manufacturing precision
If new variety characteristics are developed through controlled-cross, then distinctive flower color and plant habit are achieved, but breeding complexity increases
Solution Approach 1:
The breeding process applies preliminary action by first selecting parent varieties with complementary traits (SuperCal® Cherry Improved for flower color and KLECA17395 for plant habit), then performing controlled crosses to predetermined designs before selecting and propagating offspring that exhibit the desired combination of characteristics
Solution Approach 2:
The invention employs feedback mechanisms in the selection process, where offspring plants are evaluated against specific criteria (flower size, color, plant habit) and only those meeting the standards are selected for propagation, ensuring consistent reproduction of the desired traits in successive generations
