Gamad VI Crapemyrtle Compact Growth and Mildew Resistance

Solution Overview

Problem

There is a lack of compact, purple flowering crapemyrtle varieties with mildew resistance and early flowering capabilities, as existing varieties either lack compact growth or sufficient resistance to mildew.

Innovation Solution

The development of the 'Gamad VI' crapemyrtle plant, a Lagerstroemia hybrid, which exhibits a compact-mounded habit, mildew resistance, early flowering, and abundant deep red/purple flowers, derived from open-pollinated seed of 'Pocomoke' and stabilized through asexual reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If compact growth habit is selected for, then plant size is reduced, but flower color variety and mildew resistance may be compromised

Engineering Contradiction:

Improveplant sizeVSAvoidmildew resistance

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting and stabilizing specific genetic parameters through asexual reproduction. The variety 'Gamad VI' was selected from open-pollinated seed of 'Pocomoke' and stabilized through multiple generations of asexual reproduction to maintain consistent characteristics including compact size, mildew resistance, and flower color. This ensures the plant maintains compact growth habit while simultaneously achieving reliable mildew resistance and deep red/purple flower coloration.

2Loss of time

If early flowering is selected for, then flowering time is advanced, but plant maturity and disease resistance may be compromised

Engineering Contradiction:

Improveflowering timeVSAvoiddisease resistance

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting and stabilizing specific genetic parameters through asexual reproduction. The variety 'Gamad VI' was selected from open-pollinated seed of 'Pocomoke' and stabilized through multiple generations of asexual reproduction to maintain consistent characteristics including compact size, mildew resistance, and flower color. This ensures the plant maintains compact growth habit while simultaneously achieving reliable mildew resistance and deep red/purple flower coloration.

3Ease of manufacture

If deep red/purple flower color is selected for, then flower color intensity is increased, but availability of compact varieties with this trait is reduced

Engineering Contradiction:

Improveflower color qualityVSAvoidvariety availability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility
