Calibrachoa CBRZ0029 Cultivar Breeding for pH Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Calibrachoa hybrida cultivar with specific characteristics such as mid-sized raspberry colored flowers, darker 'eye', yellow inside the flower at the base of the petals, and semi-trailing plant habit that is not highly sensitive to soil pH, which are not met by existing varieties.
Innovation Solution
The development of Calibrachoa hybrida 'CBRZ0029' through a planned breeding program, combining traits from proprietary breeding lines '4135-1' and '4132-3', resulting in a cultivar with fixed characteristics retained through asexual reproduction, including good branching and adaptability to varying environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Calibrachoa varieties are used, then general flowering characteristics are maintained, but specific desired traits (mid-sized raspberry colored flowers with darker eye, yellow base, semi-trailing habit, and low soil pH sensitivity) cannot be achieved
Solution Approach 1:
The patent combines multiple breeding lines with different desirable traits through hybridization. Specifically, it merges the soil pH adaptability trait with the specific flower color characteristics (mid-sized raspberry colored flowers with darker eye and yellow base) and semi-trailing plant habit into a single unified cultivar 'CBRZ0029', resolving the contradiction between adaptability and trait precision.
2Reliability
If a planned breeding program is conducted to achieve specific traits, then distinct and fixed characteristics are obtained, but time and resource investment increase
Solution Approach 1:
The patent employs preliminary action by conducting systematic hybridization between selected breeding lines '4135-1' and '4132-3' before mass propagation. This preliminary breeding phase establishes the fixed genetic characteristics that will be reliably reproduced through subsequent asexual propagation, ensuring trait stability before commercial deployment.
Solution Approach 2:
Once the desired characteristics are established through breeding, the patent uses asexual reproduction (cutting propagation) to create identical copies of the selected plant. This copying process preserves the fixed characteristics reliably across multiple generations without requiring repeated breeding cycles, thus reducing time loss in the long term.

AI summary
A new Calibrachoa plant named ‘CBRZ0029’ particularly distinguished cultivar has mid-sized raspberry colored flowers with a darker “eye” and yellow inside the flower at the base of the petals, green foliage, good branching, semi-trailing plant habit, and has little sensitivity to soil pH.
