Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new inbred corn lines is a slow and costly process that requires expertise, and existing inbred parent corn lines lose commercial competitiveness over time, necessitating the creation of improved germplasm with enhanced yield, disease resistance, and adaptability.
Innovation Solution
The introduction of the inbred corn line SLD34BM, which is a yellow dent corn line with specific physiological and morphological characteristics, and methods for producing and breeding SLD34BM-derived corn plants, including self-pollination, sib-pollination, and hybrid production, along with techniques for enhancing seed resistance to stress conditions and disease using agricultural chemicals and genetic markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional inbreeding techniques are used to develop new inbred corn lines, then new germplasm with desirable traits can be obtained, but the process is slow and costly
Solution Approach 1:
The patent applies preliminary action by pre-developing and characterizing inbred line SLD34BM with specific desirable traits (yield, disease resistance, adaptability) before using it in hybrid combinations. This preparatory work establishes a ready-to-use parental line that can be immediately deployed in breeding programs, eliminating the need to develop new inbreds from scratch each time.
Solution Approach 2:
The patent employs copying by creating and propagating inbred line SLD34BM as a standardized, replicable genetic resource. Once the inbred line is developed and characterized, it can be copied and used repeatedly across multiple breeding programs and locations, significantly reducing the time and cost of developing new germplasm compared to traditional one-at-a-time inbreeding approaches.
2Stability of the object's composition
If existing inbred parent corn lines are used over time, then breeding programs can maintain continuity, but the lines lose commercial competitiveness
Solution Approach 1:
The patent applies dynamics by presenting SLD34BM not as a static, fixed line but as a dynamic genetic resource that can be continuously improved and recombined. The inbred line serves as a stable foundation that can be dynamically combined with different partners and updated with new traits, maintaining both breeding continuity and commercial competitiveness through flexible recombination rather than relying on static existing lines.
Solution Approach 2:
The patent employs parameter changes by introducing SLD34BM with specifically optimized parameters (yield potential, disease resistance profiles, adaptability characteristics) that differ from traditional inbred lines. These changed parameters restore commercial competitiveness to the breeding program while maintaining the stability needed for continuous breeding operations.
3Manufacturing precision
If self-pollination and sib-pollination methods are used to produce inbred seeds, then uniform inbred lines can be obtained, but the process requires careful isolation and control
Solution Approach 1:
The patent applies self-service by developing SLD34BM with inherent characteristics that facilitate its own propagation and identification. The inbred line's uniformity and stable traits allow it to serve its own breeding needs, reducing the complexity of external isolation and control mechanisms required compared to traditional methods where each crossing requires meticulous manual management.
