Solution Overview

Problem

There is a need for a new cultivar of Canna generalis that exhibits distinctive apricot-colored blossoms, dark foliage, large petals, and a rapid self-cleaning flowering habit, which are not adequately addressed by existing varieties like 'Liberty Coral Rose', 'Futurity Pink', and 'Liberty Watermelon'.

Innovation Solution

The cultivar 'Can Do Apricot Dark Leaf' is developed through a cross-pollination between 'Liberty Coral Rose' and 'PW-AP-DK04', resulting in a unique combination of traits including apricot-colored blossoms, dark foliage, larger petals, and a more compact, self-cleaning flowering habit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If existing varieties like 'Liberty Coral Rose' are used, then foliage color and flower production are maintained, but distinctive apricot-colored blossoms and dark foliage are not achieved

Engineering Contradiction:

Improvebreeding processVSAvoiddistinctive characteristics

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The breeding program segmented the selection process by first establishing distinct parent lines with specific traits ('Liberty Coral Rose' for foliage and flower production, 'PW-AP-DK04' for apricot coloration), then systematically combining them through controlled cross-pollination to achieve the desired cultivar with multiple distinctive characteristics simultaneously

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention changed multiple parameters simultaneously through selective breeding: flower color parameter (to apricot), foliage color parameter (to dark), petal size parameter (to large), and flowering habit parameter (to rapid self-cleaning), creating a cultivar that differs from parents in multiple key parameters

Inventive Principle:

Principle #35Parameter changes

2Area of moving object

If larger petals and bloom size are produced, then visual impact is improved, but plant compactness and self-cleaning habit are compromised

Engineering Contradiction:

Improvepetal sizeVSAvoidself-cleaning flowering habit

Core Design Contradiction:

Area of moving objectVSEase of operation

Solution Approach 1:

The breeding program merged multiple desirable traits into a single cultivar by combining large petal size from selected parents with compact plant structure and rapid self-cleaning flowering habit, achieving a synthesis where all traits work together rather than competing

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If rapid self-cleaning flowering habit is achieved, then maintenance is improved, but flower color intensity and bloom size are reduced

Engineering Contradiction:

Improveself-cleaning rateVSAvoidbloom characteristics

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The cultivar achieves rapid self-cleaning through parameter changes in flower maturation timing and petal senescence rate, while maintaining apricot color intensity and large bloom size through genetic selection that decouples these parameters, allowing fast turnover without sacrificing aesthetic quality

Inventive Principle:

Principle #35Parameter changes
