Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ornamental plant breeders face challenges in developing superior New Guinea Impatiens varieties due to the unpredictability of genetic combinations and the need for extensive research efforts to achieve desired traits, as existing methods lack control over DNA-level selection and environmental factors.
Innovation Solution
The development of the New Guinea Impatiens variety SAKIMP043, which is stable and uniform, allows for vegetative propagation and breeding techniques such as recurrent selection, backcrossing, and gene editing to introduce desired traits, enabling the creation of new varieties with specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop New Guinea Impatiens varieties, then genetic diversity can be explored, but the process becomes unpredictable and requires extensive research time and resources
Solution Approach 1:
The patent applies preliminary action by establishing a stable, uniform base variety (SAKIMP043) before conducting breeding operations. This pre-established genetic foundation allows breeders to start with known, predictable traits and systematically introduce desired characteristics through controlled crosses, rather than exploring genetic diversity from scratch. The uniformity of SAKIMP043 serves as a reliable starting point that reduces the time needed for selection and stabilization in subsequent generations.
Solution Approach 2:
The patent employs parameter changes by shifting from traditional exploratory breeding to a systematic approach using a standardized base variety. By changing the fundamental parameter of genetic starting material from diverse, uncharacterized sources to a single, well-defined uniform variety, the breeding process becomes more predictable and efficient. This parameter change enables controlled introduction of specific traits while maintaining overall plant uniformity.
2Adaptability or versatility
If traditional breeding methods are used to develop New Guinea Impatiens varieties, then various traits can be combined, but extensive research efforts and costs are required
Solution Approach 1:
The patent applies preliminary action by pre-establishing a uniform base variety with known, stable characteristics before undertaking trait combination efforts. This preliminary groundwork eliminates the need to repeatedly characterize and stabilize basic plant traits, allowing researchers to focus their efforts specifically on introducing and selecting for desired new traits. The uniform genetic background of SAKIMP043 serves as a consistent platform for systematic trait introduction.
Solution Approach 2:
The patent employs copying by using the uniform base variety SAKIMP043 as a replicated starting material for multiple breeding programs. Instead of developing new base varieties for each breeding project, the same proven uniform variety is copied and used repeatedly as the foundation. This copying approach ensures consistency across different breeding efforts and eliminates the need to re-establish baseline uniformity for each new variety development project.
3Reliability
If uniform base varieties are used for breeding, then predictability and consistency are improved, but genetic diversity may be limited
Solution Approach 1:
The patent applies local quality by maintaining uniformity in the base variety while introducing specific, localized genetic variations for desired traits. The majority of the genome remains consistent and uniform from the SAKIMP043 base, providing predictability in overall plant characteristics. Meanwhile, specific loci or gene regions are selectively modified or introduced to add diversity only where needed for particular traits, such as flower color or disease resistance, rather than requiring genome-wide diversity.
Solution Approach 2:
The patent employs parameter changes by transitioning from a breeding model that requires genome-wide diversity to one that achieves desired variation through targeted, localized genetic changes. By changing the approach from exploring random genetic diversity to introducing specific, controlled genetic modifications into a uniform background, the system achieves both predictability (through uniform base) and adaptability (through targeted trait introduction).
