Solution Overview

Problem

There is a need for new Begonia plant cultivars with improved post-production longevity and attractive flower color that can reproduce stably and consistently across various environmental conditions.

Innovation Solution

The development of Begonia x hiemalis 'KRELARE01' through controlled breeding, combining traits such as compact and freely branching habit, dark green leaves, and large double-type bright red flowers, which exhibit excellent post-production longevity and stability across different environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If traditional Begonia breeding methods are used, then flower color variation is achieved, but postproduction longevity is insufficient

Engineering Contradiction:

Improvepostproduction longevityVSAvoidflower color stability

Core Design Contradiction:

Duration of action of stationary objectVSReliability

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled cross-pollination between specific parent plants (KV10K1753-025 and S00) to achieve optimal combinations of postproduction longevity and flower color stability. The selected cultivar 'KRELARE01' exhibits bright red flowers that maintain their color intensity and structural integrity throughout the extended postproduction period, resolving the contradiction between longevity and color stability.

2Ease of manufacture

If new flower colors are developed through breeding, then attractiveness is improved, but stability across environmental conditions deteriorates

Engineering Contradiction:

Improvecommercial production suitabilityVSAvoidenvironmental condition adaptability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The breeding program conducted preliminary controlled cross-pollination experiments to pre-select parent plants with complementary traits before developing the final cultivar. This preliminary action ensured that 'KRELARE01' would inherently possess both the desired bright red flower color and the stability to maintain it across various environmental conditions, making it suitable for commercial production without requiring additional environmental controls.

Principle #10Preliminary action

3Shape

If large double-type flowers are produced, then flower size and complexity are improved, but plant vigor and branching habit deteriorate

Engineering Contradiction:

Improveflower type and sizeVSAvoidbranching habit and growth vigor

Core Design Contradiction:

ShapeVSProductivity

Solution Approach 1:

The cultivar 'KRELARE01' exhibits local quality differentiation where the flower structures are concentrated in specific regions (axillary positions along branches) rather than uniformly distributed. This allows the plant to allocate resources efficiently, producing large double-type flowers (with multiple tepal whorls and tepaloids) at specific locations while maintaining overall plant vigor and freely branching growth habit throughout the rest of the plant structure.
