Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new inbred corn plants is a slow and costly process that requires expertise, and existing inbred 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 4HSXI1003, which is a yellow dent inbred corn line with specific physiological and morphological characteristics, along with methods for producing and breeding corn plants using techniques such as self-pollination, sib-pollination, and tissue culture to create uniform and high-yielding hybrids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional inbreeding techniques are used to develop new inbred corn lines, then genetic purity and uniformity are improved, but the process is slow and costly, reducing productivity
Solution Approach 1:
The patent applies preliminary action by using pre-existing inbred lines (4HSX1001-4HSX1010) as starting material to create the new inbred line 4HSX11003. This allows the breeding process to begin with genetically uniform parents that have already been developed, reducing the time and cost required to achieve genetic purity compared to developing entirely new lines from scratch.
Solution Approach 2:
The patent utilizes parameter changes by introducing specific genetic modifications and selecting for particular traits (yield, disease resistance, adaptability) to transform the breeding process. The inbred line 4HSX11003 is developed with specific genetic parameters that enhance performance, allowing for more efficient selection and faster development of commercially viable lines.
2Ease of manufacture
If existing inbred corn lines are used for hybrid production, then ease of manufacture is improved, but they lose commercial competitiveness over time
Solution Approach 1:
The patent applies parameter changes by developing inbred line 4HSX11003 with enhanced genetic parameters including improved yield, disease resistance, and adaptability. These modified parameters make the new inbred line more commercially competitive while maintaining the ease of hybrid production through standard inbreeding techniques.
Solution Approach 2:
The patent uses copying by creating a new inbred line (4HSX11003) that copies the successful breeding framework of existing lines (4HSX1001-4HSX1010) but incorporates improved genetic traits. This allows the industry to use familiar breeding methods while achieving enhanced commercial performance.
3Productivity
If extensive breeding efforts are made to improve corn performance, then yield and quality are improved, but the time and resource requirements increase
Solution Approach 1:
The patent applies preliminary action by using pre-developed inbred lines as parents for creating 4HSX11003. This approach reduces the breeding duration significantly compared to developing entirely new lines from scratch, as the genetic foundation is already established and verified.
Solution Approach 2:
The patent utilizes parameter changes by focusing breeding efforts on specific high-impact traits (yield, disease resistance, adaptability) rather than attempting to improve all characteristics simultaneously. This targeted approach achieves significant productivity improvements more quickly.
