Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars face challenges in combining desirable traits such as higher seed yield, disease resistance, drought tolerance, and improved fatty acid profiles, which are time-consuming to develop and require precise planning and resource efficiency.
Innovation Solution
Development of a new soybean cultivar 21430343 with integrated traits like disease resistance, herbicide tolerance, and improved fatty acid composition, achieved through traditional breeding and genetic modification techniques, including transgenic methods and CRISPR-Cas system for targeted genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to combine desirable traits, then multiple traits can be integrated, but the development process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent replaces traditional mechanical breeding methods (crossing, selection, and recombination over multiple generations) with molecular biology techniques including gene cloning, transformation, and CRISPR-Cas genome editing. This substitution allows direct manipulation of genetic material to introduce desired traits in a single step rather than requiring multiple generations of breeding, thereby dramatically reducing development time while achieving the same trait combination goals
2Adaptability or versatility
If multiple breeding objectives are pursued simultaneously, then superior varieties with multiple traits can be developed, but the complexity of the breeding program increases
Solution Approach 1:
The patent segments the complex breeding objective into individual genetic targets, each addressed by specific molecular techniques. Rather than attempting to combine multiple traits through complex multi-generation breeding programs, the invention isolates specific genes or genomic regions associated with each desired trait and introduces them independently through transformation or targeted editing, simplifying the overall program complexity while achieving comprehensive trait integration
3Ease of manufacture
If precise forward planning is implemented to reduce changes in direction, then resource efficiency improves, but the flexibility to adapt to new discoveries is reduced
Solution Approach 1:
The patent replaces traditional breeding mechanics with molecular biology tools that allow precise, targeted manipulation of the genome. This substitution enables researchers to efficiently plan and execute trait introduction while maintaining the flexibility to easily modify experimental approaches based on new genetic discoveries, as molecular techniques can be rapidly adapted to target different genes or pathways without requiring complete program redesign
