Vinfeleche New Guinea Impatiens Compact Growth and Branching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact and freely branching New Guinea Impatiens plants with attractive leaf and flower colors that can reproduce true to type through asexual propagation, as existing varieties may vary in phenotype with environmental conditions and lack desired traits like dense foliage and specific flower colors.
Innovation Solution
A new cultivar, 'Vinfeleche', developed through planned breeding, exhibiting a compact, upright, and freely branching habit with dark green leaves and numerous red-purple flowers, achieved by crossing proprietary selections of Impatiens hawkeri, which is stable and reproduces true to type through terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Impatiens varieties are propagated, then reproduction occurs, but phenotype varies with environmental conditions and does not reproduce true to type
Solution Approach 1:
The patent applies preliminary action by conducting planned breeding programs before propagation to pre-select and stabilize desired phenotypic traits. The breeding program systematically combines parental selections with predictable inheritance patterns to establish genotypes that will reliably reproduce the intended phenotype across environmental conditions, preventing phenotypic variability before it occurs.
2Volume of moving object
If compact growth habit is selected, then plant size is reduced, but branching density and foliage density may be compromised
Solution Approach 1:
The patent applies parameter changes by selectively modifying multiple genetic parameters simultaneously through controlled breeding. The breeding program adjusts internode length, branching frequency, and leaf production parameters together to achieve a balanced phenotype where compact size and dense foliage coexist, rather than optimizing single parameters in isolation.
3Quantity of substance
If freely branching habit is enhanced, then foliage density increases, but plant compactness may be reduced
Solution Approach 1:
The patent applies local quality by optimizing branching characteristics in specific regional zones of the plant. The breeding program promotes dense lateral branching throughout the lower and middle sections of the plant to create compact appearance, while allowing more open growth at the apex, creating localized variations in branching density that collectively achieve both compactness and overall foliage density.
