Calibrachoa CBRZ0004 Cultivar Hybridization for Continuous Center Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Calibrachoa cultivar with medium-sized yellow flowers that blooms early and continuously in the center of the plant, exhibiting a highly branched habit, which existing varieties do not adequately provide.
Innovation Solution
The development of the Calibrachoa spp. cultivar 'CBRZ0004' through hybridization, characterized by its early blooming, continuous center flowering, and highly branched habit, achieved through asexual reproduction and selection in a greenhouse in Gilroy, California, with specific traits such as flower size, foliage color, and branching patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Calibrachoa varieties are used, then they may have certain flowering characteristics, but they do not provide the combination of early blooming, continuous center flowering, and highly branched habit with medium-sized yellow flowers
Solution Approach 1:
The patent combines multiple desirable traits (early blooming, continuous center flowering, highly branched habit, medium-sized yellow flowers) from different parent plants into a single new cultivar through controlled hybridization, creating a unified plant that exhibits all these characteristics simultaneously
Solution Approach 2:
The patent performs preliminary selection of parent plants with specific desirable traits before hybridization, and conducts systematic evaluation of progeny plants to identify those exhibiting the target combination of characteristics, streamlining the breeding process
2Adaptability or versatility
If hybridization is performed to create new varieties with specific traits, then novel combinations of characteristics are achieved, but the breeding process requires significant time and resources
Solution Approach 1:
The patent uses disposable vegetative cuttings for propagation and evaluation of progeny plants, allowing rapid assessment of multiple hybrid combinations without long-term maintenance of extensive plant collections, thereby reducing time and resource investment
3Manufacturing precision
If selection is made based on multiple characteristics, then a distinct new variety is obtained, but differentiation from similar varieties requires detailed comparison and observation
Solution Approach 1:
The patent uses flower color (yellow) and foliage color characteristics as distinctive markers to differentiate the new cultivar from similar varieties, providing visually apparent means of identification and verification of variety distinctness
Solution Approach 2:
The patent evaluates and documents multiple discrete characteristics (flower size, flowering time, branching pattern, foliage color) separately, allowing systematic comparison and clear differentiation from other varieties through cumulative trait analysis
