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 need for improved germplasm with enhanced yield, disease resistance, and adaptability.
Innovation Solution
The introduction of the inbred corn line 1EEXI3087, 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 stable inbred and hybrid corn plants, and the use of transgenic approaches to introduce desirable traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional inbreeding techniques (self-pollination and sib-pollination) are used to develop new inbred corn lines, then uniform and stable inbred plants can be obtained, but the process is slow and costly
Solution Approach 1:
The patent applies preliminary action by establishing a structured multi-generation inbreeding program that prepares and selects plants in advance through systematic self-pollination and sib-pollination protocols. This preliminary structured approach accelerates the development of stable inbred lines by pre-planning selection criteria and pollination strategies across generations, reducing the time required to achieve uniformity compared to traditional ad-hoc methods
2Ease of manufacture
If existing inbred parent corn lines are used repeatedly, then breeding experience and expertise are maintained, but the lines lose commercial competitiveness over time
Solution Approach 1:
The patent applies dynamics by implementing an ongoing, iterative inbreeding and selection program that continuously develops new inbred lines rather than statically relying on existing ones. The method enables dynamic renewal of germplasm through systematic generation of improved inbred lines with enhanced yield and disease resistance, maintaining commercial competitiveness while preserving breeding expertise through structured protocols
Solution Approach 2:
The patent applies parameter changes by selectively improving specific traits of new inbred lines compared to existing lines. The method focuses on enhancing yield, disease resistance, and adaptability parameters through controlled inbreeding and selection, creating genetically improved lines that surpass parental lines in key productivity parameters while maintaining breeding process consistency
3Stability of the object's composition
If inbreeding is continued beyond a sufficient amount, then genetic uniformity is increased, but vigor of the lines decreases
Solution Approach 1:
The patent applies partial action by implementing controlled inbreeding for a specific number of generations (F2 through F5) to achieve sufficient genetic uniformity without excessive inbreeding. The method selectively applies self-pollination and sib-pollination protocols for predetermined generations, then introduces cross-pollination to restore vigor, optimizing the balance between uniformity and vigor by avoiding excessive inbreeding depression
4Manufacturing precision
If new inbred lines are developed through traditional methods, then genetic diversity is reduced for uniformity, but adaptability to wider production areas is needed
Solution Approach 1:
The patent applies local quality by developing inbred lines with specific localized adaptations to different production environments. The method creates distinct inbred lines (e.g., 1EEXI3087) with traits optimized for particular regions or conditions, allowing each line to have uniform genetics tailored to local requirements while maintaining overall genetic diversity across the breeding program through multiple line development
