Solution Overview

Problem

The existing calla lily varieties lack a wide range of colors with a large, classic flower shape suitable for pot flower production, and there is a need for a cultivar that retains specific characteristics through asexual reproduction.

Innovation Solution

A new cultivar of Zantedeschia sprengeri, named 'Halifax', is developed through a breeding program, combining traits such as a spathe that changes color from white to purple, purple leaf margin, and colored flower buds, achieved through tissue culture reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing calla lily varieties are used, then production is simple, but the color range is limited and flower shape is not classic

Engineering Contradiction:

Improvecolor rangeVSAvoidbreeding program complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple parental varieties with different color traits (C03001 with purple maculation, E439 with green-yellow spathe) to create a hybrid cultivar that exhibits a wide range of colors including purple, white, green-yellow, and bi-color patterns, thereby expanding the color versatility while maintaining a classic flower shape

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The new cultivar exhibits local quality variations within the spathe structure, with different zones displaying distinct colors (purple maculation on white background, green-yellow base with purple overlay), creating a multi-colored effect that enhances visual appeal while maintaining the classic calla lily form

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If a new cultivar with multiple characteristics is created, then visual appeal is improved, but consistency through reproduction becomes challenging

Engineering Contradiction:

Improvevisual appealVSAvoidcharacteristic retention

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent establishes a controlled breeding program that preliminarily combines desired traits through selective crossing before propagation. The cultivar was developed through systematic crossing of selected parents, followed by selection of superior progeny, ensuring that the combination of traits (color transitions, leaf margins, flower shape) is genetically stabilized before commercial propagation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent utilizes tissue culture parameters and environmental controls to maintain characteristic consistency. By controlling cultivation conditions and using standardized tissue culture protocols, the new cultivar reproduces true to type, ensuring that the complex color patterns and morphological traits are reliably maintained across generations

Inventive Principle:

Principle #35Parameter changes

AI summary

‘Halifax’ is a new variety of calla lily plant having inflorescences with a white/purple-colored spathe that produces 3-10 inflorescences per tuber. The height of the top of an inflorescence above the soil can reach up to 47 cm, and the leaves are dark green with whitish spots and have a leathery texture.
