Calibrachoa CBRZ0008 Cultivar pH Tolerance and Trait Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Calibrachoa hybrida cultivar with specific flower and foliage characteristics that are stable across different environmental conditions and not sensitive to soil pH, as existing varieties do not consistently exhibit desired traits under varying temperature, light intensity, and day length.
Innovation Solution
The development of Calibrachoa hybrida 'CBRZ0008' through hybridization, characterized by mid-sized purple-blue flowers with a darker 'eye' and yellow base, green foliage, good branching, and a moderately compact, semi-trailing habit, which retains its characteristics through successive generations of asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Calibrachoa varieties are grown under varying environmental conditions, then their growth and flowering continue, but their flower color, foliage characteristics, and overall appearance become inconsistent and sensitive to soil pH
Solution Approach 1:
The patent applies parameter changes by selectively breeding plants with specific genetic parameters that confer pH tolerance and environmental stability. The breeding program identified and fixed specific genetic parameters in 'CBRZ0008' that make the plant less sensitive to soil pH variations and environmental fluctuations, thereby achieving reliable trait expression across different growing conditions.
2Manufacturing precision
If Calibrachoa varieties are bred for specific flower colors and characteristics, then desired aesthetic traits are achieved, but the traits may not be firmly fixed and can vary with environmental conditions
Solution Approach 1:
The patent applies preliminary action by conducting extensive preliminary breeding and selection work to firmly fix desired traits before commercial release. The breeders performed multiple generations of selective breeding and environmental testing to ensure that flower color, foliage characteristics, and growth habits were genetically stabilized in 'CBRZ0008' before it was introduced as a new cultivar, preventing later variation.
Solution Approach 2:
The patent applies feedback by systematically observing and measuring plant traits across multiple environments and generations, then using this information to guide further breeding decisions. The breeders monitored flower color intensity, foliage characteristics, and growth patterns under varying conditions, and used this feedback to select parent plants that would produce more stable offspring, progressively improving trait consistency.
3Volume of moving object
If Calibrachoa plants are bred for compact growth habit, then space efficiency is improved, but flowering time is delayed
Solution Approach 1:
The patent applies parameter changes by balancing multiple growth parameters in 'CBRZ0008' to achieve an optimal compromise between plant size and flowering time. The cultivar was bred to maintain a moderately compact habit suitable for container growth while adjusting other parameters such as internode length and branching patterns to ensure timely flowering, avoiding the extreme delay seen in highly compact varieties.

AI summary
A new Calibrachoa plant named ‘CBRZ0008’ 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.
