Solution Overview

Problem

There is a need for new Begonia plant cultivars with improved post-production longevity and attractive flower color that can thrive under various environmental conditions and cultural practices, while maintaining stable genetic traits.

Innovation Solution

The development of Begonia x hiemalis cultivar 'KRBEVCH01' through controlled breeding, which exhibits an upright to spreading plant habit, moderately vigorous growth, semi-double red flowers held above the foliage, and excellent post-production longevity, differing from parent cultivars in flower color and type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If conventional Begonia cultivars are used, then they have simple flower types, but they lack attractive flower color and have poor postproduction longevity

Engineering Contradiction:

Improvepostproduction longevityVSAvoidstability of genetic traits

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent applies parameter changes by modifying flower color parameters (from pink or light red purple to red) and flower type parameters (from single to semi-double) through controlled cross-pollination breeding, thereby improving postproduction longevity and attractiveness while maintaining genetic stability

Inventive Principle:

Principle #35Parameter changes

2Reliability

If new flower colors and types are developed through breeding, then postproduction longevity improves, but the complexity of breeding program increases

Engineering Contradiction:

Improveattractive flower color and longevityVSAvoidbreeding program complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by conducting controlled cross-pollination between specifically selected parent plants (KV11K1912-001 and S00) before the breeding season, preparing the progeny in advance for selection. This preliminary breeding action enables the development of cultivars with improved flower color and longevity while managing breeding program complexity through planned rather than random approaches

Inventive Principle:

Principle #10Preliminary action

3Productivity

If Begonia plants are bred for vigorous growth, then productivity increases, but adaptability to various environmental conditions may be reduced

Engineering Contradiction:

Improvegrowth vigor and flowering frequencyVSAvoidadaptability to environmental conditions

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by developing cultivar 'KRBEVCH01' that simultaneously achieves multiple functions: vigorous growth habit, freely flowering habit, attractive red semi-double flowers, and excellent postproduction longevity. This multi-functional cultivar maintains both productivity and adaptability to various environmental conditions and cultural practices

Inventive Principle:

Principle #6Universality (Multi-functionality)
