Solution Overview

Problem

There is a need for a new Ranunculus cultivar that exhibits distinct and stable traits such as intense black flower color, medium flower size, and high productivity, which are not consistently achieved in existing varieties under varying environmental conditions.

Innovation Solution

The cultivar 'ABUMBREON' is developed through planned breeding, combining the traits of seed parent 'N 240-04' and pollen parent 'N28-2000/2', resulting in a double flower with larger size and increased flowering stems, with stable propagation through vegetative division and tissue culture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing Ranunculus varieties are grown under varying environmental conditions, then environmental adaptability is tested, but flower color intensity and consistency deteriorate

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidflower color consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies parameter changes by selectively breeding for specific genetic traits that stabilize flower color intensity. The new cultivar 'ABUMBREON' was developed through controlled crossing and selection to fix the intense black coloration trait, making it resistant to environmental variations. This resolves the contradiction by changing the genetic parameters of the plant to maintain consistent phenotypic expression across different environmental conditions.

2Area of moving object

If flower size is increased, then visual impact is improved, but productivity per unit area deteriorates

Engineering Contradiction:

Improveflower sizeVSAvoidproductivity per unit area

Core Design Contradiction:

Area of moving objectVSProductivity

Solution Approach 1:

The patent applies local quality by optimizing the flower size specifically for cut flower market requirements rather than maximizing it uniformly. The cultivar 'ABUMBREON' produces flowers with diameter of 8.5-9.5 cm, which is larger than standard varieties but balanced with other traits like intense color and double flower structure. This localized optimization of flower size alongside other quality parameters resolves the contradiction between visual impact and productivity per unit area.

Inventive Principle:

Principle #3Local quality

3Shape

If double flower structure is developed, then ornamental value is improved, but genetic stability becomes more difficult to maintain

Engineering Contradiction:

Improvedouble flower structureVSAvoidgenetic stability

Core Design Contradiction:

ShapeVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by performing multiple generations of controlled crossing and selection before releasing the cultivar. The double flower trait was established through systematic breeding programs conducted by the inventor, with careful selection of parent plants and monitoring of offspring. This preliminary genetic stabilization ensures that the double flower structure is heritably fixed in the cultivar 'ABUMBREON', resolving the contradiction between ornamental value and genetic stability.

AI summary

A new and distinct Ranunculus cultivar named ‘ABUMBREON’ is disclosed, characterized by an intense black color to the flowers. The flower size is medium, double flowers are produced throughout the flowering season. The new variety is a Ranunculus, normally produced as a cut flower and potentially useful as an ornamental plant.
