Solution Overview

Problem

There is a need for a new Ranunculus cultivar that exhibits unique and stable characteristics such as distinct flower color, larger flower size, and increased flower production, which are not consistently met by existing varieties under varying environmental conditions.

Innovation Solution

The development of the Ranunculus cultivar 'ABPERKONS' through planned breeding, which combines the traits of proprietary seed and pollen parents, resulting in soft pink and green-yellow flowers, strong and vigorous plants, and an above-average number of flower stems, while maintaining stability across multiple generations through vegetative division and tissue culture propagation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If existing Ranunculus varieties are used, then basic flowering characteristics are maintained, but flower color uniqueness, flower size, and flower production quantity are insufficient

Engineering Contradiction:

Improveflower production quantityVSAvoidenvironmental adaptability

Core Design Contradiction:

Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by systematically varying breeding parameters including crossing different parental varieties with distinct color genetics, selecting for specific flower size parameters, and controlling propagation parameters through tissue culture techniques. This resulted in a cultivar with 9-12 cm flower diameter (larger than parents) and increased flower stem production while maintaining stability across generations.

Inventive Principle:

Principle #35Parameter changes

2Area of moving object

If flower size is increased, then visual impact and ornamental value improve, but plant vigor and growth strength may be compromised

Engineering Contradiction:

Improveflower sizeVSAvoidplant vigor

Core Design Contradiction:

Area of moving objectVSStrength

Solution Approach 1:

The patent applies local quality by concentrating genetic resources specifically into the flower head region while maintaining separate optimization for the vegetative portion. The breeding program selected for large flower diameter (9-12 cm) as a localized trait while independently selecting for strong, vigorous plant growth and healthy rhizome development, allowing both large flowers and strong plants to coexist without compromising either attribute.

Inventive Principle:

Principle #3Local quality

3Shape

If unique flower color combinations are developed, then ornamental distinctiveness increases, but genetic stability and true-to-type reproduction may be compromised

Engineering Contradiction:

Improveflower colorVSAvoidgenetic stability

Core Design Contradiction:

ShapeVSStability of the object's composition

Solution Approach 1:

The patent applies copying through tissue culture propagation, which creates genetically identical copies of the selected plant. This asexual reproduction method ensures that the unique color combination (light pink with green-yellow center) is precisely replicated in all propagated plants, maintaining genetic stability and true-to-type reproduction across multiple generations without the variability introduced by sexual reproduction.

Inventive Principle:

Principle #26Copying

AI summary

A new and distinct Ranunculus cultivar plant named `ABPERKONS` is disclosed, characterized by a unique flower color combination including soft pink and green-yellow. Plants are strong and produce an excellent quantity of flowering stems with large size flowers throughout the flowering season. The new variety is a Ranunculus, normally produced as a cut flower and potentially useful as an ornamental plant.
