Calibrachoa CBRZ0011 Cultivar Breeding for pH Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Calibrachoa hybrida cultivar with distinct mid-sized purple flowers, green foliage, good branching, late flowering, and a moderately compact, semi-trailing plant habit that is less sensitive to soil pH, which existing varieties fail to consistently provide.
Innovation Solution
The development of Calibrachoa hybrida 'CBRZ0011' through a planned breeding program, combining these characteristics, which are retained through asexual reproduction and exhibit minimal sensitivity to environmental variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Calibrachoa varieties are used, then they provide certain flower colors and growth habits, but they fail to consistently provide the specific combination of mid-sized purple flowers with darker eye, yellow base, green foliage, good branching, late flowering, and moderate compact semi-trailing habit with low soil pH sensitivity
Solution Approach 1:
The patent combines multiple desirable traits from different parent plants through controlled hybridization to create a new cultivar that simultaneously exhibits mid-sized purple flowers with darker eye, yellow base, green foliage, good branching, late flowering, and moderate compact semi-trailing habit with reduced soil pH sensitivity
Solution Approach 2:
The breeding program selectively modifies genetic parameters to achieve the desired phenotype, including flower color intensity, plant habit compactness, branching pattern, and pH tolerance thresholds, resulting in a cultivar with optimized trait expression
2Reliability
If a planned breeding program is used to develop new cultivars, then distinct and stable characteristics can be achieved, but the development time and complexity increase
Solution Approach 1:
The breeding program performs preliminary selective crosses between parent plants with known desirable traits, followed by systematic evaluation of progeny to identify and propagate individuals exhibiting the target combination of characteristics, thereby establishing stable traits through controlled preliminary generations
Solution Approach 2:
The breeding process incorporates continuous phenotypic evaluation and selection feedback, where offspring are assessed against desired trait criteria and only those meeting the standards are propagated further, ensuring stable inheritance of target characteristics through iterative selection

AI summary
A new Calibrachoa plant named ‘CBRZ0011’ particularly distinguished by the mid-sized purple flowers with a darker “eye” and yellow inside the flower at the base of the petals, green foliage, good branching, late flowering, and a moderately compact, semi-trailing plant habit, and has little sensitivity to soil pH.
