Solution Overview

Problem

There is a need for new calla lily cultivars with yellow spathes that retain distinctive characteristics through asexual reproduction, as existing varieties lack the desired color and leaf maculation density.

Innovation Solution

The 'Yellow Jacket BLZ' cultivar, resulting from the cross of 'Sunglow' and 'Pot of Gold' Zantedeschia varieties, exhibits yellow spathes and high-density leaf maculation, achieved through asexual micropropagation by tissue culture, maintaining its characteristics in successive propagations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional calla lily varieties are used, then breeding program requirements are met, but yellow spathes and high-density leaf maculation are not achieved

Engineering Contradiction:

Improvedistinctive characteristics retentionVSAvoidleaf maculation density

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent uses micropropagation by tissue culture to create exact genetic copies of the calla lily plant, ensuring that the distinctive characteristics including yellow spathes and high-density leaf maculation are perfectly replicated in successive propagations without variation

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If existing calla lily varieties are used, then commercial availability is maintained, but desired color and leaf maculation density are lacking

Engineering Contradiction:

Improvecolor variationVSAvoidcharacteristic consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Through asexual reproduction via tissue culture, the invention creates genetically identical copies that perfectly preserve the unique color characteristics and leaf maculation patterns, ensuring complete consistency across all propagations

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The breeding program systematically controlled breeding parameters including parental selection, pollination timing, and tissue culture conditions to achieve the specific yellow spathe color and high-density leaf maculation characteristics

Inventive Principle:

Principle #35Parameter changes

3Manufacturing precision

If new cultivars are developed through breeding, then distinctive characteristics are achieved, but reproductive consistency may vary

Engineering Contradiction:

Improveinflorescence productionVSAvoidcharacteristic stability

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

The patent employs micropropagation to create exact genetic replicas of the bred cultivar, ensuring that the inflorescence production characteristics and all other traits remain perfectly stable across successive propagations without the variation that might occur with sexual reproduction

Inventive Principle:

Principle #26Copying
