Juniperus FARROWJVBF Cultivar Blue Foliage and Fruit Traits

Solution Overview

Problem

There is a need for a distinct cultivar of Juniperus virginiana that exhibits unique characteristics such as blue foliage, dense pyramidal shape, and abundant small blue fruit, which are not consistently observed in existing varieties under varying environmental conditions.

Innovation Solution

The cultivar 'FARROWJVBF' is developed through open-pollination breeding, characterized by blue foliage, a dense pyramidal shape, and abundant small blue fruit, propagated via softwood cuttings, and has been stabilized through five generations of reproduction, distinguishing it from other Juniperus varieties like 'Burkii' and its seed parent.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing Juniperus varieties are used, then they have established horticultural characteristics, but they do not exhibit the unique blue foliage, dense pyramidal shape, and abundant small blue fruit simultaneously

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by conducting controlled open-pollination breeding programs and selecting specific parental plants with desirable traits before the cultivar is fully developed. Five generations of propagation were performed in advance to stabilize the unique characteristics of blue foliage, dense pyramidal shape, and abundant small blue fruit, ensuring trait reliability before commercial release.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the cultivar is propagated through multiple generations, then trait stability is improved, but time and resources for breeding are increased

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies copying by using softwood cuttings to propagate the cultivar 'FARROWJVBF' across five generations. This vegetative propagation method creates genetically identical copies of the selected plant, rapidly stabilizing and reproducing the unique traits without the time-consuming process of sexual reproduction and selection that would otherwise be required.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If the cultivar exhibits unique characteristics like blue foliage and fruit, then horticultural distinctiveness is improved, but differentiation from existing varieties requires detailed comparison and analysis

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies color changes as a key distinguishing feature by selecting and propagating a Juniperus cultivar with blue foliage and blue fruit. These color characteristics provide immediate visual differentiation from existing varieties like 'Burkii' (silver/gray foliage) and the seed parent (green foliage), making the cultivar's distinctiveness easily detectable and measurable without complex analysis.

Inventive Principle:
Principle #32Color changes
