Hosta B201 Cultivar Slug Resistance and Foliage Traits

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing Hosta cultivars lack distinct dark red petioles and flower stems, glossy green foliage with broad yellow and creamy white margins, thick and strong leaves, vigorous growth habit, and high resistance to slugs, which are unique characteristics exhibited by the new cultivar 'B201'.

Innovation Solution

The new cultivar 'B201' features dark red leaf petioles and flower stems, glossy green foliage with broad yellow and creamy white margins, thick and strong leaves, a vigorous growth habit, and high resistance to slugs, which are stable and reproduced through asexual propagation by division and tissue culture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional Hosta cultivars are used, then general foliage characteristics are maintained, but distinct dark red petioles and flower stems, glossy green foliage with broad yellow and creamy white margins, thick and strong leaves, vigorous growth habit, and high resistance to slugs are not achieved

Engineering Contradiction:

Improveslug resistanceVSAvoidfoliage characteristic variety

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by selecting and propagating a chimeral mutation with specific physiological and morphological parameters that differ from the parent plant. The mutant exhibits dark red petioles and flower stems, glossy green foliage with broad yellow and creamy white margins, and thick strong leaves - representing specific parameter changes in color, texture, and structural properties that simultaneously improve slug resistance while maintaining distinctive foliage characteristics.

Inventive Principle:

Principle #35Parameter changes

2Strength

If leaf thickness and substance are increased, then slug resistance and leaf strength are improved, but leaf margin thickness may be reduced

Engineering Contradiction:

Improveleaf strengthVSAvoidleaf margin thickness

Core Design Contradiction:

StrengthVSShape

Solution Approach 1:

The patent applies local quality by demonstrating that different regions of the leaf exhibit different properties. The leaf margins are broad and creamy white with substantial thickness, while the leaf blade maintains strong substance and thickness for slug resistance. This regional differentiation allows the leaf margin to be both visually distinctive and structurally sound, resolving the contradiction between overall leaf strength and margin characteristics.
