New Guinea Impatiens Cultivar Fisimp Salm Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new, distinct cultivars of New Guinea Impatiens with attractive and large flowers that exhibit a freely-branching and moderately vigorous growth habit, as existing cultivars may vary in performance and appearance under different environmental conditions.
Innovation Solution
The cultivar 'Fisimp Salm' is developed through planned breeding, combining the traits of upright and outwardly spreading growth, medium green-colored leaves, and large salmon pink-colored flowers, achieved through cross-pollination of proprietary selections of Impatiens hawkeri, which are stable and reproduce true to type via asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cultivars are used, then they may have certain growth habits, but they vary in performance and appearance under different environmental conditions
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar with specifically optimized growth parameters (freely-branching habit, moderate vigor) that remain stable across varying environmental conditions. The breeding program selected for consistent phenotypic expression of key parameters including branching pattern, flower size, and color stability regardless of environmental variations.
2Shape
If new cultivars are developed with large and attractive flowers, then flower quality is improved, but growth habit control becomes more difficult
Solution Approach 1:
The patent applies local quality by differentiating between various plant parts and their desired characteristics. The cultivar exhibits locally optimized traits: freely-branching habit for overall plant structure, moderate vigor for growth rate, and large attractive flowers for reproductive structures. This localized optimization of different plant regions resolves the contradiction between flower quality and growth control.
3Adaptability or versatility
If proprietary selections are crossed to create new cultivars, then genetic diversity is improved, but breeding program complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases and components: selecting specific proprietary selections with code numbers, controlled cross-pollination events, progeny evaluation stages, and cultivar designation. This segmented approach to breeding manages complexity by breaking down the genetic diversity creation process into manageable, systematic steps.
