Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn breeding techniques face challenges in developing new inbred corn lines that maintain commercial competitiveness over time, with existing inbred parent lines losing vigor and requiring costly and expertise-intensive processes to produce hybrid corn varieties with improved yield and trait technologies.
Innovation Solution
The development of a new inbred corn line, D065046, which exhibits increased grain yield and stability, along with methods for producing and treating seeds to enhance resistance to stress conditions, such as cold, drought, and diseases, thereby improving hybrid performance and flexibility in crop management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional inbreeding techniques are used to develop new inbred corn lines, then commercial competitiveness is maintained initially, but vigor decreases over time and additional inbreeding merely increases seed quantity without improving performance
Solution Approach 1:
The patent segments the breeding process into distinct phases: using inbred line D065046 as a stable foundation parent that can be crossed with multiple different second parents to generate diverse hybrid combinations. This segmentation allows the foundation line to be developed once and reused repeatedly without degradation, separating the development of genetic stability from hybrid vigor generation.
Solution Approach 2:
The patent applies preliminary action by developing inbred line D065046 in advance with optimized traits (yield, stress resistance, uniformity) before using it in hybrid production. This pre-developed line serves as a ready-to-use foundation that eliminates the need for repeated inbreeding cycles, maintaining vigor while enabling continuous hybrid improvement through crossing with different second parents.
2Stability of the object's composition
If extensive inbreeding is performed to develop new inbred lines, then homozygosity increases, but the process becomes costly and expertise-intensive
Solution Approach 1:
The patent implements self-service by creating inbred line D065046 with inherently stable homozygous characteristics that maintain their genetic composition without requiring continuous complex breeding interventions. The line's self-maintaining homozygosity reduces the need for expensive and expertise-intensive breeding operations, allowing breeders to focus resources on crossing experiments rather than line maintenance.
3Productivity
If existing inbred parent lines are used repeatedly, then commercial competitiveness is maintained, but they lose vigor and require additional inbreeding to produce improved hybrids
Solution Approach 1:
The patent applies preliminary action by developing inbred line D065046 in advance with optimized traits (yield, stress resistance, uniformity) before using it in hybrid production. This pre-developed line serves as a ready-to-use foundation that eliminates the need for repeated inbreeding cycles, maintaining vigor while enabling continuous hybrid improvement through crossing with different second parents.
Solution Approach 2:
The patent makes inbred line D065046 universal by designing it as a foundation line that can be crossed with multiple different second parents to generate diverse hybrid combinations. This multi-functionality allows the same foundation line to produce various improved hybrids for different applications, extending its usable duration and commercial competitiveness without requiring repeated inbreeding.
