Solution Overview

Problem

There is a need for new Petunia varieties with interesting colors and attractive plant forms that can reproduce stably and consistently exhibit unique characteristics across varying environmental conditions.

Innovation Solution

The development of the Petunia hybrida cultivar 'DLITRDFIRE' through open pollination, which exhibits a mounded growth habit, abundant flowering, and distinct red flower color, achieved through asexual reproduction by vegetative cuttings, ensuring stability across multiple generations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If open pollination is used to create new varieties, then genetic diversity and unique characteristics are improved, but stability and consistency across generations deteriorate

Engineering Contradiction:

Improveunique characteristicsVSAvoidstability across generations

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The breeding program segments the breeding process into distinct phases: open pollination for genetic diversity, followed by selection and asexual reproduction for stabilization. This allows the program to capture unique characteristics while subsequently maintaining them consistently across generations through clonal propagation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary action by performing open pollination and selection before large-scale propagation. The unique characteristics are established through controlled open pollination and selection processes before the cultivar is propagated asexually, ensuring that the desired traits are fixed before widespread reproduction begins.

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If asexual reproduction by vegetative cuttings is used, then stability and consistency of characteristics are improved, but genetic diversity deteriorates

Engineering Contradiction:

Improvestability of characteristicsVSAvoidgenetic diversity

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent uses copying through asexual reproduction by vegetative cuttings to create identical copies of the selected parent plant. This ensures that the unique characteristics established during the breeding phase are perfectly replicated and maintained across multiple generations without genetic variation.

Inventive Principle:

Principle #26Copying

3Productivity

If the plant exhibits abundant flowering with small flowers, then ornamental value is improved, but flower size deteriorates

Engineering Contradiction:

Improveabundant floweringVSAvoidflower size

Core Design Contradiction:

ProductivityVSVolume of moving object

Solution Approach 1:

The patent applies parameter changes by selecting for a specific combination of flowering parameters: high flower quantity and small flower size. The cultivar 'DLITRDFIRE' was selected and propagated for its specific parameter profile of producing numerous small flowers, representing an optimization of the flowering parameters for ornamental purposes.

Inventive Principle:

Principle #35Parameter changes
