Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new hybrid corn varieties is a slow and costly process that requires expertise, and existing hybrids lose commercial competitiveness over time, necessitating a continuous need for novel varieties with improved characteristics such as increased grain yield and resistance to insects, weeds, and diseases.
Innovation Solution
The development of a new yellow dent hybrid corn variety, 122971, produced from a cross of inbred varieties SLB01 and DS-046358, which exhibits improved grain yield and is treated with seed coatings or impregnations to enhance resistance to adverse conditions, along with processes for producing novel inbred and hybrid plants through controlled pollination and seed treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If new hybrid corn varieties are developed through traditional breeding processes, then improved grain yield and resistance to pests are achieved, but the development process is slow and costly
Solution Approach 1:
The patent applies preliminary action by using pre-developed inbred lines (SLB01 and DS-046358) that have been bred and tested in advance. These inbred lines serve as ready-to-use parental materials that can be quickly crossed to produce new hybrids, eliminating the need to develop inbred lines from scratch and significantly reducing the overall development time while maintaining improved grain yield and pest resistance characteristics
2Adaptability or versatility
If traditional breeding methods are used to create new hybrids, then genetic diversity and adaptability are improved, but the process requires extensive expertise and resources
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct, manageable components: (1) selection of pre-developed inbred lines with specific desirable traits, (2) controlled crossing of these inbred lines to produce F1 hybrids, and (3) evaluation of the resulting hybrids. This segmentation simplifies the overall process by using modular, pre-characterized building blocks rather than requiring complex de novo breed, reducing the expertise and resources needed while maintaining genetic diversity and adaptability
3Stability of the object's composition
If existing hybrid corn varieties are used continuously, then production stability is maintained, but commercial competitiveness is lost over time
Solution Approach 1:
The patent applies parameter changes by systematically varying key breeding parameters including selecting different inbred line combinations (SLB01 × DS-046358), adjusting crossing protocols, and evaluating multiple trait parameters (grain yield, pest resistance, adaptability). This generates new hybrid varieties with improved or differentiated characteristics that maintain production stability while regaining commercial competitiveness through enhanced performance traits
