Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new hybrid corn varieties is a slow and costly process, requiring expertise and numerous steps, and existing hybrids lose commercial competitiveness over time, necessitating the creation of novel varieties with improved characteristics such as increased grain yield and resistance to insects, weeds, and diseases.
Innovation Solution
The development of hybrid corn variety 980003, produced from a cross of inbred varieties 7RN401 and XJH58, which exhibits improved grain yield and resistance traits, along with seed treatment options to enhance crop flexibility and protect against adverse conditions, is achieved through careful selection and breeding processes, including self-pollination and cross-pollination techniques to produce uniform and vigorous F1 hybrid progeny.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional hybrid corn variety development processes are used, then uniform F1 hybrid progeny can be produced, but the process is slow and costly
Solution Approach 1:
The patent applies preliminary action by pre-selecting and pre-breeding inbreds with specific desirable traits before the actual hybridization. The inbreds are developed through multiple generations of self-pollination and selection to ensure uniformity and vigor are restored in the F1 generation, thereby reducing the overall development time while maintaining precision.
Solution Approach 2:
The patent utilizes parameter changes by modifying breeding strategies to incorporate molecular markers and genomic selection. This allows for more efficient selection of inbreds with desired traits, accelerating the breeding process while maintaining the uniformity and vigor characteristics of the F1 hybrid progeny.

3Productivity
If existing hybrid corn varieties are used, then current crop production is maintained, but commercial competitiveness is lost over time
Solution Approach 1:
The patent applies continuity of useful action by maintaining a continuous breeding program that constantly generates new hybrid varieties with improved traits. The breeding process is ongoing, with new inbreds being developed and crossed to create F1 hybrids that maintain and improve upon commercial competitiveness, ensuring continuous adaptation to changing agricultural needs.
Solution Approach 2:
The patent utilizes parameter changes by modifying breeding strategies to incorporate molecular markers and genomic selection. This allows for more efficient selection of inbreds with desired traits, accelerating the breeding process while maintaining the uniformity and vigor characteristics of the F1 hybrid progeny.
