Calibrachoa USCAL41401 Cultivar Breeding for Uniform Habit and Unique Flower Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Calibrachoa plant cultivars with uniform, freely-branching habits and unique flower coloration that excel in garden performance, as existing cultivars may vary significantly with environmental conditions and lack distinct flower patterns.
Innovation Solution
The development of the Calibrachoa cultivar 'USCAL41401' through controlled cross-pollination, which exhibits a compact, upright growth habit, dense and bushy appearance, freely flowering habit, and distinctive white flowers with a central greyed purple star pattern and yellow throat, differing from parent cultivars in flower color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Calibrachoa cultivars are grown under varying environmental conditions, then their phenotype may vary significantly, but this leads to inconsistency in garden performance and appearance
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic parameters through controlled cross-pollination. The breeder selected parent plants with desirable traits (compact habit, freely-branching structure) and crossed them to produce offspring with consistent phenotypic parameters that remain stable across varying environmental conditions, achieving reliability without sacrificing adaptability
2Stability of the object's composition
If Calibrachoa plants are bred for uniform growth habit, then plant architecture becomes consistent, but flower coloration and patterns may become less diverse
Solution Approach 1:
The patent applies local quality by differentiating between different plant characteristics and applying selective breeding pressure to specific local traits. The breeder maintained uniformity in growth habit parameters (compact, upright, mounding form) while simultaneously preserving and enhancing flower coloration diversity (white flowers with greyed purple star patterns and yellow throats) through careful selection of parent plants with complementary traits
3Object-generated harmful factors
If controlled cross-pollination is used to create new cultivars, then unique flower characteristics are achieved, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-selecting parent plants with specific desirable traits before initiating cross-pollination. The breeder identified and selected parent plants code 11CJ37-09 and code 11CJ42 that possessed complementary characteristics (compact habit, freely-branching structure, desirable flower colors) and performed controlled cross-pollination on May 7, 2011, thereby streamlining the breeding process and reducing complexity while achieving unique flower characteristics in the offspring
