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 the need for novel hybrid corn varieties with improved characteristics to enhance yield, adaptability, and resistance to insects, weeds, and diseases.
Innovation Solution
A new yellow dent hybrid corn variety, designated 1374594, is developed by crossing inbred varieties SRD02BM and LLD06BM, with specific physiological and morphological characteristics, and treated seeds are used to enhance resistance to adverse conditions, incorporating seed treatment options for improved crop flexibility and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If new hybrid corn varieties are developed through traditional breeding processes, then improved yield and characteristics are achieved, but the process is slow and costly
Solution Approach 1:
The patent applies preliminary action by using pre-developed inbred lines (SRD02BM and LLD06BM) that have already been bred and tested over multiple generations. These inbred lines serve as ready-made parental stocks that can be immediately crossed to produce the F1 hybrid, eliminating the need to start breeding from scratch and significantly reducing the time required to develop a new variety.
Solution Approach 2:
The patent utilizes parameter changes by crossing two specific inbred lines with complementary genetic characteristics to produce an F1 hybrid with enhanced traits. The cross between SRD02BM (providing drought tolerance and disease resistance) and LLD06BM (providing yield potential and adaptability) creates a hybrid with optimized parameters that differ from the parent lines, achieving improved productivity through genetic recombination.
2Reliability
If new hybrid corn varieties are developed through traditional breeding processes, then improved characteristics are achieved, but the process is costly
Solution Approach 1:
The patent applies preliminary action by using pre-developed inbred lines that have already been bred and tested over multiple generations for desired traits such as disease resistance and pest tolerance. These inbred lines (SRD02BM and LLD06BM) serve as ready-made parental stocks with known genetic characteristics, eliminating the need to start breeding from scratch and significantly reducing the time and resources required to develop a new variety with reliable protective traits.
Solution Approach 2:
The patent uses copying by utilizing the proven genetic framework of existing inbred lines that have been successfully bred and tested. Instead of creating new genetic combinations from scratch, the invention copies and recombines proven genetic elements from SRD02BM and LLD06BM to produce an F1 hybrid with reliable resistance characteristics, reducing the cost and complexity of developing new protective traits.
3Adaptability or versatility
If existing hybrid corn varieties are used, then immediate availability is maintained, but commercial competitiveness is lost over time
Solution Approach 1:
The patent applies parameter changes by crossing two specific inbred lines with complementary genetic characteristics to produce an F1 hybrid with enhanced traits. The cross between SRD02BM (providing drought tolerance and disease resistance) and LLD06BM (providing yield potential and adaptability) creates a hybrid with optimized parameters that differ from the parent lines, achieving improved productivity through genetic recombination.
Solution Approach 2:
The patent uses composite materials by combining the genetic strengths of two different inbred lines (SRD02BM and LLD06BM) to create a composite F1 hybrid genome. This composite genetic structure integrates the adaptive traits from both parents, resulting in a hybrid with enhanced versatility and commercial competitiveness that can perform reliably across diverse production areas.
