Calibrachoa CBRZ0038 Cultivar Hybridization pH Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Calibrachoa hybrida cultivar with distinct mid-sized purple-blue flowers, yellow centers, mid-green foliage, good branching, early flowering, and semi-trailing habit that is less sensitive to soil pH, as existing varieties may not consistently exhibit these traits under varying environmental conditions.
Innovation Solution
The development of Calibrachoa hybrida 'CBRZ0038' through hybridization of '4132-4' and '4151-1' in a controlled environment, resulting in a cultivar with fixed characteristics retained through asexual reproduction, including specific flower and foliage descriptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Calibrachoa varieties are used, then they may exhibit certain flower colors and plant habits, but they show sensitivity to soil pH and environmental variations causing inconsistent trait expression
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar through controlled hybridization that alters the genetic parameters to reduce sensitivity to soil pH. The new cultivar 'CBRZ0038' exhibits improved reliability in trait expression across varying environmental conditions compared to existing varieties, achieving this through selective breeding that modifies the plant's physiological parameters for greater environmental stability.
2Productivity
If existing Calibrachoa varieties are used, then they may have certain flowering times and plant habits, but they do not consistently exhibit early flowering with good branching
Solution Approach 1:
The patent applies preliminary action by performing controlled hybridization between specific parent plants before the flowering season, allowing the new cultivar to be pre-selected and propagated with desired traits. The hybridization process in 2014-2015 preceded the demonstration of consistent early flowering and good branching characteristics, ensuring these traits are established before commercial deployment.
Solution Approach 2:
The new cultivar achieves improved productivity through parameter changes in flowering time and branching architecture. The cultivar exhibits early flowering with consistent good branching patterns across multiple generations, representing a modification of developmental parameters achieved through selective breeding and hybridization.
3Shape
If existing Calibrachoa varieties are used, then they may have certain flower sizes and colors, but they do not exhibit the distinct mid-sized purple-blue flowers with yellow centers
Solution Approach 1:
The patent applies local quality by creating distinct color zones within the flower structure. The new cultivar 'CBRZ0038' exhibits mid-sized purple-blue flowers with distinctive yellow centers, where different parts of the same flower have different color qualities. This local differentiation of color properties enhances aesthetic distinctiveness while maintaining consistent flower size.
Solution Approach 2:
The flower exhibits composite color characteristics combining purple-blue outer petals with yellow central regions. This composite color pattern, achieved through genetic hybridization, creates a distinctive aesthetic appearance that differentiates the cultivar from existing varieties while maintaining uniform flower size and shape.

AI summary
A new Calibrachoa plant named ‘CBRZ0038’ particularly distinguished by mid-sized purple blue flowers with a darker “eye” and yellow inside the flower at the base of the petals, mid-green foliage, good branching, early flowering, semi-trailing plant habit, and has little sensitivity to soil pH.
