Calibrachoa Cultivar USCAL58205 Phenotypic Consistency Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Calibrachoa plant cultivars with uniform plant habit, freely branching growth, attractive flowers, and good garden performance, as existing cultivars may vary significantly with environmental conditions and cultural practices.
Innovation Solution
The development of the Calibrachoa cultivar 'USCAL58205' through planned breeding, which exhibits a compact, mounding, and freely branching growth habit, with pink-colored flowers having greyed purple centers, and demonstrates good garden performance, achieved by crossing proprietary seedling selections CJ06 and C459-04.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Calibrachoa cultivars are grown under varying environmental conditions, then their phenotypic expression varies significantly, but this leads to inconsistency in plant habit, flowering uniformity, and garden performance
Solution Approach 1:
The patent applies parameter changes by selecting and fixing specific genetic parameters through controlled cross-pollination between parent plants with desirable traits. The F1 hybrid plants exhibit stable phenotypic parameters (plant habit, flower color, branching pattern) that remain consistent across varying environmental conditions, thereby achieving reliability without sacrificing adaptability
2Productivity
If Calibrachoa plants are bred for vigorous growth and continuous flowering, then productivity and attractiveness improve, but plant habit becomes less compact and uniform
Solution Approach 1:
The patent applies local quality by creating plants with differentiated regional characteristics: the central plant body maintains a compact, mounding habit with uniform shape, while the periphery exhibits vigorous branching and continuous flowering. This allows the plant to simultaneously achieve compact uniformity in overall form and high productivity in flowering output
