Solution Overview

Problem

There is a need for a new Phalaenopsis cultivar with attractive, large, light purple, striped flowers and reddish-purple lips suitable for potted plant production that can reproduce true to type through asexual reproduction methods.

Innovation Solution

The development of the Phalaenopsis hybrid 'PHA601241' through cross-pollination of proprietary parents, followed by asexual reproduction via meristem tissue culture, resulting in plants with distinct floral characteristics such as flat flower shape and weak lip curvature, which are stable across generations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If cross-pollination of proprietary parents is performed to create new floral characteristics, then flower attractiveness and distinctiveness are improved, but genetic stability and true-to-type reproduction are worsened

Engineering Contradiction:

Improveflower shapeVSAvoidgenetic stability

Core Design Contradiction:

ShapeVSStability of the object's composition

Solution Approach 1:

The breeding program segmented the complex trait inheritance by focusing on specific floral characteristics (flower shape, lip curvature, coloration) and selecting parent plants with complementary traits. This allowed systematic development of distinct floral features while maintaining control over genetic outcomes through controlled cross-pollination and subsequent selection of stable progeny

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Preliminary selection of parent plants with specific desirable traits was performed before cross-pollination. The parent plants were carefully chosen and characterized to ensure that the resulting hybrid would exhibit the desired floral characteristics while maintaining genetic stability for true-to-type reproduction in commercial propagation

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If asexual reproduction via meristem tissue culture is used, then true-to-type reproduction is improved, but propagation speed and productivity are worsened

Engineering Contradiction:

Improvetrue-to-type reproductionVSAvoidpropagation speed

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The meristem tissue culture process utilized parameter optimization including controlled temperature regimes, specific hormone concentrations, and standardized culture media compositions to maximize both the fidelity of true-to-type reproduction and the multiplication rate. These parameter adjustments enabled efficient large-scale propagation while maintaining genetic consistency

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The propagation system established continuous cycles of meristem excision, culture, rooting, and acclimatization that maintained uninterrupted production flow. This continuous operation enabled sustained high-volume propagation of genetically identical plants, simultaneously achieving productivity and genetic stability

Inventive Principle:

Principle #20Continuity of useful action
