Physocarpus SMPOCGT Cultivar Mildew Resistance and Color Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Physocarpus cultivars with improved resistance to mildew and unique coloration characteristics that are stable across different environmental conditions.
Innovation Solution
The cultivar 'SMPOCGT' exhibits strong red/orange spring leaf flush, dark maroon summer leaves, green underside, bright red stems, and light pink to white flowers, with enhanced mildew resistance, distinguishing it from existing varieties like 'Center Glow' and 'SMNPOBLR'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If open-pollination breeding is used to create new Physocarpus cultivars, then new coloration characteristics and mildew resistance can be achieved, but the stability of these traits across generations and environmental conditions becomes uncertain
Solution Approach 1:
The patent applies preliminary action by conducting multiple generations of selective breeding and evaluation before releasing the cultivar. The breeder performed open-pollination breeding, then systematically evaluated numerous offspring over multiple growing seasons to identify those with stable, desirable traits. This preliminary selection process ensured that only plants with consistent coloration and mildew resistance were propagated, resolving the contradiction between introducing new traits and maintaining stability.
Solution Approach 2:
The patent employs feedback through continuous observation and evaluation of plant performance across different environmental conditions. The breeder monitored coloration consistency and mildew resistance over multiple seasons and generations, using this feedback information to select superior plants for propagation. This iterative feedback process ensured that the cultivar 'SMPOCGT' achieved both the desired new traits and stable expression of those traits.
2Shape
If selection for unique coloration traits is emphasized, then distinctive horticultural characteristics are achieved, but resistance to mildew may be compromised
Solution Approach 1:
The patent applies local quality by selecting for specific localized traits in different parts of the plant. The breeder evaluated and selected for distinctive leaf coloration patterns (red/orange spring flush, maroon summer leaves, green undersides) while simultaneously assessing mildew resistance. This multi-criteria selection process ensured that plants with unique coloration characteristics also possessed the desired disease resistance, resolving the contradiction between aesthetic traits and health resistance.
Solution Approach 2:
The patent employs composite materials in the sense of combining multiple desirable traits into a single cultivar. The breeder integrated distinctive coloration characteristics (red stems, maroon leaves, green undersides) with mildew resistance into one unified plant variety. This composite approach created a cultivar that simultaneously expresses multiple unique traits without compromising any single characteristic, including both coloration and disease resistance.

AI summary
A new and distinct cultivar of Physocarpus plant named ‘SMPOCGT’ is disclosed, characterized by red-orange spring leaves, turning dark maroon with green undersides in summer. Plants have bright red stems, and light pink to white flowers producing bright reddish-pink seed heads. Plants produce bright red fruit. The new cultivar is a Physocarpus, normally produced as an outdoor garden or container plant.
