Solution Overview

Problem

Existing cultivars of Panicum virgatum lack unique ornamental traits such as compact habits, strong stature, and distinct foliage or flower colors, limiting their landscape appeal.

Innovation Solution

The development of a new cultivar, 'Nonesory', which exhibits a compact and vase-shaped plant habit, nonlodging clumping foliage, upright flowering spikes, deep rose-colored flowers, and moderate growth rate, addressing the need for novel ornamental traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing Panicum virgatum cultivars are used, then they provide basic ornamental value, but they lack unique ornamental traits such as compact habits, strong stature, and distinct foliage or flower colors

Engineering Contradiction:

Improveornamental appealVSAvoidunique traits consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by selectively breeding Panicum virgatum plants to achieve specific morphological parameters including compact plant habit, vase-shaped form, nonlodging clumping foliage, and upright flowering spikes. The cultivar 'Nonesory' exhibits distinct parameter values for height (0.91m), spread (0.69m), and floral color (deep rose) that differentiate it from existing cultivars and enhance its ornamental appeal while maintaining stable inheritance of these traits

Inventive Principle:

Principle #35Parameter changes

2Shape

If Panicum cultivars are bred for compact habits and strong stature, then ornamental appeal is improved, but plant height and spread are reduced

Engineering Contradiction:

Improvecompact vase-shaped habitVSAvoidplant height

Core Design Contradiction:

ShapeVSLength of stationary object

Solution Approach 1:

The patent applies local quality by creating a cultivar with differentiated structural characteristics in various parts of the plant. The 'Nonesory' cultivar exhibits compact clumping foliage with upright flowering spikes positioned above the foliage, creating a vase-shaped form where the lower portion is dense and compact while the upper portion features elevated floral displays. This local differentiation achieves both compact habit and strong visual appeal without excessive height reduction

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If Panicum cultivars are bred for unique foliage or flower colors, then ornamental distinctiveness is improved, but genetic stability may be compromised

Engineering Contradiction:

Improvefoliage and flower color variationVSAvoidtrait inheritance stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies this principle through tissue culture propagation using meristematic tissue, which provides a reliable and stable method for reproducing the cultivar. Tissue culture allows for the production of genetically identical plants that maintain the unique ornamental traits of 'Nonesory' including its green foliage and deep rose flowers, ensuring trait inheritance stability while enabling widespread propagation of this uniquely colored cultivar

Inventive Principle:
