Solution Overview

Problem

There is a need for a new cultivar of Argyranthemum frutescens that combines large, white inflorescences, compact and full plant habit, dark green foliage, and good plant vigor, which are not adequately met by existing cultivars like 'Arg Whit' and 'Neptune'.

Innovation Solution

The development of the 'Sascot Whit' cultivar, resulting from the hybridization of 'Arg Whit' and 'AR03-158-2', which exhibits larger inflorescences, darker green foliage, greater plant vigor, and a more compact habit compared to its parents, and is asexually reproduced through cuttings and tissue culture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If existing cultivars like 'Arg Whit' and 'Neptune' are used, then they provide basic flowering performance, but they fail to combine large white inflorescences with compact plant habit and dark green foliage

Engineering Contradiction:

Improveinflorescence sizeVSAvoidplant habit

Core Design Contradiction:

Quantity of substanceVSShape

Solution Approach 1:

The patent combines multiple desirable traits from different parental lines through hybridization. The female parent 'Arg Whit' contributes large white inflorescences, while the male parent contributes compact plant habit and dark green foliage. The resulting cultivar 'Sascot Whit' merges these traits into a single plant that exhibits all three characteristics simultaneously, resolving the contradiction between inflorescence size and plant habit.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If existing cultivars are used, then they provide basic plant vigor, but they do not achieve the combination of good plant vigor with continuous flowering from spring to fall

Engineering Contradiction:

Improveplant vigorVSAvoidflowering duration

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The cultivar 'Sascot Whit' achieves multi-functionality by combining robust plant vigor with extended continuous flowering capability. The plant maintains strong health and vitality while simultaneously providing reliable flowering throughout the entire spring to fall season, making it universally suitable for various landscaping applications and eliminating the need to choose between vigor and flowering duration.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If existing cultivars are used, then they provide basic ornamental value, but they do not offer the unique combination of large white inflorescences with dark green foliage for patio planters and container plantings

Engineering Contradiction:

Improveornamental valueVSAvoidsuitability for patio planters and container plantings

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The cultivar 'Sascot Whit' exhibits local quality through its contrasting color combination of large white inflorescences against dark green foliage. This creates a visually striking local contrast that enhances ornamental value specifically in compact settings like patio planters and containers, where the plant's size and color contrast can be fully appreciated in limited spaces.
