Solution Overview

Problem

There is a need for a new Ranunculus cultivar that exhibits unique and stable traits such as vibrant yellow flower color, large corolla, extra double flowers, and above-average flower production, which are not consistently achieved under varying environmental conditions.

Innovation Solution

The cultivar 'ABUMACATLO' is developed through planned breeding, characterized by vibrant yellow flower color, large corolla, extra double flowers, and above-average flower stems, with stable reproduction through vegetative division and tissue culture, distinguishing it from its seed and pollen parents and commercial varieties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional Ranunculus varieties are used, then basic flowering is achieved, but flower color vibrancy, corolla size, and flower production quantity remain average or suboptimal

Engineering Contradiction:

Improveflower production quantityVSAvoidtrait stability under varying environmental conditions

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled crosses between selected parent plants, creating new combinations of traits that resulted in enhanced flower production quantity and improved environmental stability of key characteristics

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The inventor conducted preliminary selection and characterization of parent plants with desirable traits before performing the cross, ensuring that the resulting cultivar would inherit and stabilize the desired characteristics of vibrant yellow color, large corolla, and high flower production

Inventive Principle:

Principle #10Preliminary action

2Area of moving object

If flower size is increased to 8-10 cm, then ornamental value is enhanced, but reproductive organ transformation may affect fertility

Engineering Contradiction:

Improvecorolla areaVSAvoidreproductive function

Core Design Contradiction:

Area of moving objectVSReliability

Solution Approach 1:

The cultivar exhibits localized transformation where the gynoecium and androecium are converted into petal-like structures in specific regions of the flower, while maintaining the overall floral function and enabling continued reproduction through alternative mechanisms

Inventive Principle:

Principle #3Local quality
