Solution Overview

Problem

There is a need for a new Ranunculus cultivar that exhibits unique characteristics such as specific flower color, shape, and vase life, which are not adequately met by existing varieties.

Innovation Solution

The development of the Ranunculus cultivar 'ABOGMA' through planned breeding, which combines lavender and green color in the corolla, a rounded flower shape, deeply ruffled petals, exceptionally long vase life, and high productivity, achieved through asexual reproduction and tissue culture propagation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing Ranunculus varieties are used, then basic flower characteristics are met, but unique color combinations, flower shape, and vase life are insufficient

Engineering Contradiction:

Improvevase lifeVSAvoidcolor combination variety

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled crossing between parent plants with different color characteristics. The F1 generation exhibited a unique lavender-green color combination and rounded flower shape that differed from both parents, demonstrating parameter changes in color composition and floral morphology that simultaneously improved vase life and color versatility.

2Productivity

If conventional breeding methods are used, then genetic diversity is achieved, but propagation efficiency and trait stability are limited

Engineering Contradiction:

Improvepropagation efficiencyVSAvoidtrait stability

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

Tissue culture propagation was employed to create exact genetic copies of the selected F1 plant exhibiting the desired lavender-green coloration and rounded flower shape. This asexual reproduction method produces clones that are genetically identical to the parent, ensuring trait stability and true-to-type reproduction across multiple generations while dramatically increasing propagation efficiency compared to conventional seed-based methods.

3Ease of manufacture

If parent varieties with white to pale pink flowers are used, then basic horticultural characteristics are maintained, but unique color combinations are not achieved

Engineering Contradiction:

Improvebreeding program simplicityVSAvoidflower color

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The breeding program focused on specific local qualities of the parent plants - selecting for particular color characteristics in the corolla. The cross between 'PPBsfRS159.05' (white to pale pink) and '68CMT03' (lighter pink) was designed to combine specific color genes, resulting in the F1 generation's unique lavender-green coloration. This targeted selection of local color qualities achieved the desired floral appearance while maintaining breeding program simplicity.

AI summary

A new and distinct Ranunculus cultivar named ‘ABOGMA’ is disclosed, characterized by a distinctive color combination in the corolla of green and lavender. The flower has a rounded shape when fully open, and the petals are deeply ruffled. This variety has an exceptionally long vase life as a cut flower. The new variety is a Ranunculus, normally produced as a cut flower and also potentially useful as an ornamental plant.
