Solution Overview

Problem

There is a need for a distinct and stable Vanda cultivar that exhibits a freely flowering bloom habit with specific coloration and environmental adaptability, as existing varieties lack consistent traits under varying environmental conditions.

Innovation Solution

The cultivar 'SPCDW1809' is developed through controlled pollination, exhibiting unique characteristics such as light yellow dorsal sepals and lateral petals with greyed-red and purple suffusion, and a labellum with greyed-red and yellow-green radial stripes, maintained through six generations of mericloning, demonstrating stability and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a new Vanda cultivar is developed through controlled pollination to achieve specific coloration and flowering habits, then the uniqueness and distinctiveness of the cultivar is improved, but the stability of traits across generations and environmental conditions may worsen

Engineering Contradiction:

Improvetrait stabilityVSAvoidenvironmental adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The cultivar underwent six generations of mericloning with confidential testing and propagation before commercial release, allowing preliminary selection and stabilization of desired traits (abundant flowering, specific coloration patterns) under controlled conditions. This preliminary action ensured trait stability was established before facing varying environmental conditions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cultivar exhibits phenotypic variations in response to environmental parameters such as temperature, day length, and light intensity, while maintaining genotypic stability. The plant adapts its flowering habits, flower size, and coloration intensity based on environmental conditions without losing its distinctive characteristics.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the cultivar is kept in restricted access greenhouses and laboratories for confidential testing, then the stability and purity of the cultivar is maintained, but the time required for testing and propagation increases

Engineering Contradiction:

Improvecultivar purityVSAvoidtesting duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Six generations of mericloning and confidential testing were completed in restricted facilities before commercial release. This preliminary action ensured the cultivar's stability and purity were thoroughly verified under controlled conditions, preventing future issues with trait instability or contamination.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The restricted facilities served multiple functions: maintaining cultivar purity through controlled propagation, conducting stability testing across generations, and preparing plants for commercial release. This multi-functionality optimized the use of restricted access facilities while achieving multiple objectives.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the cultivar exhibits phenotypic variation with environmental changes, then the adaptability and versatility of the plant is improved, but the consistency of specific traits may worsen

Engineering Contradiction:

Improveenvironmental responseVSAvoidphenotypic consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The cultivar demonstrates controlled phenotypic plasticity where environmental parameters (temperature, light intensity, day length) influence specific traits such as flower size, coloration intensity, and flowering abundance. The genotype remains stable while phenotypic expression adapts to environmental conditions, allowing the plant to thrive in varying climates.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Instead of attempting to eliminate phenotypic variation, the cultivar embraces environmental responsiveness as a desirable trait. The plant maintains genotypic stability while allowing phenotypic expression to vary naturally with environmental conditions, turning potential inconsistency into adaptability.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A new and distinct Vanda plant named ‘SPCDW1809’ which is characterized by a freely flowering bloom habit, with an abundance of large coral-colored flowers carried within or slightly above the foliage, a dorsal sepal and lateral petals which are moderately dotted greyed-purple, lateral sepals which are heavily dotted and blotched greyed-purple, a labellum with a dark greyed-purple central lobe and yellow-green lateral lobes which are radially striped with greyed-orange, and the stability of these characteristics from generation to generation.
