Solution Overview

Problem

There is a need for new Verbena cultivars with large inflorescences and attractive flower coloration that can reproduce stably and maintain unique characteristics across varying environmental conditions.

Innovation Solution

The cultivar 'Suntapisofpi' is developed through a breeding program in Shiga, Japan, resulting in a Verbena hybrida with a spreading and vigorous growth habit, intense purple flowers, and deeper leaf dissection, distinct from its parents and other cultivars like Sunmaref TP-P, achieved through controlled cross-pollination and asexual reproduction by terminal cuttings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a breeding program creates new Verbena cultivars with large inflorescences and attractive flower coloration, then the ornamental value is improved, but the stability of reproduction across generations may be compromised

Engineering Contradiction:

Improveornamental valueVSAvoidreproduction stability

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The breeding program performed preliminary cross-pollination between selected parent plants (T205-2 and T207-4) to pre-establish the desired genetic combination for large inflorescences and attractive purple coloration before asexual reproduction, ensuring the cultivar 'Suntapisofpi' inherits stable ornamental traits

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses asexual reproduction by terminal cuttings to create exact genetic copies of the selected flowering plant, preserving the unique ornamental characteristics (intense purple flowers, large inflorescences, deeply dissected leaves) across successive generations without genetic variation

Inventive Principle:

Principle #26Copying

2Ease of manufacture

If the Verbena cultivar is selected for intense purple flower coloration and large inflorescences, then the aesthetic appeal is improved, but the plant may become more sensitive to environmental variations

Engineering Contradiction:

Improveaesthetic appealVSAvoidenvironmental tolerance

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The breeding program selected parent plants with specific genetic parameters that confer both intense purple coloration and environmental adaptability, balancing aesthetic appeal with tolerance to temperature variations and different cultural practices

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If the Verbena is propagated by asexual reproduction to maintain trait stability, then the genetic consistency is improved, but the ability to adapt to new environmental conditions is reduced

Engineering Contradiction:

Improvegenetic consistencyVSAvoidenvironmental adaptability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The breeding program preliminarily selected parent plants with both desired ornamental traits and environmental adaptability before asexual reproduction, ensuring that the genetically consistent copies maintain both trait stability and environmental tolerance

Inventive Principle:

Principle #10Preliminary action
