Solution Overview

Problem

There is a need for a new and distinct variety of Aster hybrida that combines specific characteristics such as compact plant habit, vigor, and unique floral features, which are not adequately met by existing varieties like 'Victoria Fanny', and this variety needs to be stabilized through asexual reproduction while being resistant to environmental variations.

Innovation Solution

The development of 'Synhen Thefirst' Aster hybrida, resulting from controlled hybridization in a controlled breeding environment, which exhibits a unique combination of characteristics including compact growth, rapid flowering, and specific floral traits, and is propagated through vegetative cuttings to ensure consistent asexual reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If open-pollinated hybridization is used to create new Aster varieties, then genetic diversity and unique floral characteristics are achieved, but the stability and consistency of traits across generations are compromised

Engineering Contradiction:

Improvegenetic diversityVSAvoidtrait consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The breeding process is segmented into distinct phases: open-pollinated hybridization for genetic diversity, followed by asexual reproduction through vegetative cuttings for trait stabilization. This segmentation allows each phase to optimize for its specific goal without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Asexual reproduction through vegetative cuttings is performed as a preliminary action to stabilize and fix the desirable traits obtained from hybridization before commercial propagation. This ensures trait consistency is established early in the propagation process.

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If vegetative cuttings are used for propagation, then trait consistency and stability are achieved, but genetic diversity is reduced

Engineering Contradiction:

Improvetrait consistencyVSAvoidgenetic diversity

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

Vegetative cuttings are used as a preliminary action immediately after selecting superior hybrids to fix and stabilize desirable traits before commercial propagation, ensuring genetic uniformity while maintaining the genetic diversity achieved through prior hybridization.

Inventive Principle:

Principle #10Preliminary action

3Volume of moving object

If compact plant habit is selected for breeding, then space efficiency and garden performance are improved, but plant vigor and growth rate may be reduced

Engineering Contradiction:

Improveplant sizeVSAvoidgrowth rate

Core Design Contradiction:

Volume of moving objectVSProductivity

Solution Approach 1:

The breeding program applies local quality by selecting for compact habit specifically in the plant body while maintaining vigorous root systems and flowering capacity. This allows the plant to be space-efficient above ground while retaining productivity below ground and during flowering.

Inventive Principle:

Principle #3Local quality
