Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with improved traits such as disease resistance, herbicide tolerance, and nutritional quality, which are difficult to predict and require extensive research and time due to the complexity of genetic combinations and environmental factors.
Innovation Solution
The development of the soybean variety 01069676, which includes specific genetic modifications and breeding techniques like backcrossing and genetic transformation to introduce traits like herbicide resistance, disease resistance, and improved nutritional quality, using methods such as microprojectile bombardment and Agrobacterium-mediated transformation, while maintaining the variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity and trait combination are achieved, but the process requires extensive time and resources with unpredictable outcomes
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (herbicide resistance, disease resistance, nutritional quality) and using molecular markers to identify and track specific genetic loci before and during breeding. This allows breeders to predictably introgress target traits into elite backgrounds through backcrossing, reducing the time and uncertainty associated with conventional breeding by knowing in advance which plants carry the desired genetic modifications.
2Adaptability or versatility
If multiple traits are combined in a single soybean variety, then agronomic performance and resistance are improved, but the genetic complexity and breeding difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct stages: first developing parental lines with specific individual traits (herbicide resistance, disease resistance, nutritional quality), then systematically combining these traits through controlled backcrossing. Molecular markers are used to track and segment the inheritance of each trait independently, allowing complex multi-trait varieties to be developed through manageable sequential steps rather than attempting to combine all traits simultaneously.
Solution Approach 2:
The patent applies universality by developing a standardized backcrossing protocol with molecular marker-assisted selection that can be universally applied to introgress any desired trait into any elite soybean background. The same methodological framework (marker selection, backcrossing generations, trait validation) is used regardless of which specific traits are being combined, making the breeding program scalable and adaptable to different trait combinations without requiring entirely different approaches for each case.
3Manufacturing precision
If molecular marker-assisted selection and genetic transformation are used, then breeding precision and trait introduction are improved, but the technical complexity and cost increase
Solution Approach 1:
The patent applies the intermediary principle by using molecular markers as mediators between the visible phenotypic traits and the underlying genetic loci. These markers serve as detectable intermediaries that allow breeders to indirectly select for desired traits through DNA analysis rather than waiting for phenotypic expression. This intermediary approach enables precise tracking of trait inheritance through backcrossing generations, achieving high breeding precision while using relatively simple and cost-effective marker-based assays rather than complex genomic editing technologies.
