Innovation Solution
The development of the soybean variety D2011912, which involves crossing specific parental lines and using techniques like backcrossing and genetic transformation to introduce desired traits like herbicide resistance, disease resistance, and improved nutritional quality, while maintaining the overall morphological and physiological characteristics of the soybean variety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties with desirable traits, then the breeding process is time-consuming and unpredictable, but the development of stable, high-yielding varieties with multiple desirable traits remains challenging
Solution Approach 1:
The patent applies preliminary action by pre-selecting and pre-characterizing parental lines with known desirable traits before initiating the breeding program. The parental lines are evaluated for yield, disease resistance, and nutritional quality in advance, allowing the breeding outcomes to be more predictable and reducing the overall time required by eliminating unnecessary trial-and-error phases.
Solution Approach 2:
The patent implements feedback mechanisms through continuous monitoring and evaluation of breeding progress. Performance data from trial crops are systematically collected and used to adjust breeding strategies in real-time, enabling more predictable outcomes by learning from previous generations and optimizing selection criteria based on actual field performance.
2Productivity
If conventional breeding techniques are used, then the process is straightforward, but it fails to efficiently introduce specific genetic traits like herbicide resistance and disease resistance
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct modules, each focused on introducing specific traits (e.g., herbicide resistance, disease resistance, nutritional quality) through separate parental line selections and crossing programs. This modular approach increases the rate of trait introduction by parallelizing efforts while maintaining manageable complexity through systematic organization.
Solution Approach 2:
The patent employs multi-functionality by selecting and utilizing parental lines that possess multiple desirable traits simultaneously (e.g., lines that are both disease-resistant and high-yielding). This allows a single breeding program to introduce multiple traits efficiently without requiring separate specialized programs for each trait, thereby increasing productivity without proportionally increasing complexity.
3Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the variety becomes more comprehensive and superior, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-assembling parental lines that already carry multiple desirable traits through previous breeding work and germplasm characterization. This allows the final variety development to focus only on combining these pre-established trait combinations rather than developing each trait from scratch, significantly reducing the overall breeding program duration while achieving comprehensive trait inclusion.
Solution Approach 2:
The patent merges multiple trait-introduction programs into a unified breeding strategy by identifying complementary parental lines that possess different desirable traits and combining them through strategic crosses. This merging approach allows simultaneous progress on multiple traits within a single integrated program, achieving comprehensive variety development without linearly increasing time requirements.
