Solution Overview

Problem

There is a need for new Calibrachoa plants with improved characteristics such as early and free-flowering habits, large and attractive flowers, and enhanced branching, which existing cultivars do not adequately provide.

Innovation Solution

A new Calibrachoa cultivar 'Docalraibebu' was developed through controlled cross-pollination of proprietary selections of Calibrachoa parviflora, exhibiting traits like outwardly spreading growth, freely branching, and large flowers with unique coloration, achieved through asexual reproduction by vegetative terminal cuttings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional Calibrachoa cultivars are used, then basic flowering is achieved, but early and free-flowering habits with large attractive flowers are not obtained

Engineering Contradiction:

Improveflowering rate and flower sizeVSAvoidflowering consistency

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled cross-pollination of proprietary selections, selecting for specific traits including early flowering, free-flowering habit, and large flower size. The new cultivar 'Docalraibebu' exhibits these improved parameters with consistent performance across generations.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If existing Calibrachoa varieties are planted, then some flowering is achieved, but freely branching habit is not sufficiently developed

Engineering Contradiction:

Improvebranching structureVSAvoidgrowth management

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The plant exhibits freely branching habit with multiple lateral branches per plant, creating a segmented growth structure that naturally divides the plant into multiple flowering zones. This segmentation provides both aesthetic complexity and ease of management through natural division.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If proprietary selections are cross-pollinated, then new genetic combinations are created, but stability of unique features across generations must be ensured

Engineering Contradiction:

Improvegenetic diversityVSAvoidtrait inheritance stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The breeding program conducted preliminary controlled cross-pollination between specific proprietary selections (AA17-033088-002 as female parent and AA-0584 as male parent) to create the new cultivar. Subsequent asexual reproduction by vegetative terminal cuttings has demonstrated that the unique features are stable and reproduced true to type in successive generations.
