Hybrid Corn 10823595 Yield and Disease Resistance
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 hybrid corn varieties lose commercial competitiveness over time, necessitating the need for novel varieties with improved characteristics to enhance yield production and provide flexibility against insects, weeds, and diseases.
Innovation Solution
A new yellow dent hybrid corn variety, 10823595, is developed by crossing inbred varieties SLD04 and MLW08, with specific physiological and morphological characteristics, and treated seeds are used to increase resistance to adverse conditions, incorporating seed treatments like sodium methylphenyl-pentadienate and polyvinyl alcohol to enhance plant hardiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If new hybrid corn varieties are developed through traditional breeding processes, then yield improvement and commercial competitiveness are achieved, but the development time and cost increase significantly
Solution Approach 1:
The patent applies preliminary action by developing and maintaining a library of pre-characterized inbred lines with known genetic traits and performance characteristics. Breeders can select from this pre-prepared library rather than creating new inbred lines from scratch, significantly reducing the time required to develop new hybrid varieties while maintaining yield improvement goals
2Reliability
If hybrid corn varieties are developed through extensive breeding programs, then improved characteristics and disease resistance are achieved, but the complexity and cost of the breeding process increase
Solution Approach 1:
The patent uses molecular markers as intermediaries to track and select for desirable traits during breeding. Instead of relying on complex phenotypic evaluation and multiple generations of breeding to ensure disease resistance, breeders can directly select plants with specific marker profiles that correlate with desired traits, simplifying the breeding program while maintaining reliability
3Stability of the object's composition
If existing hybrid corn varieties are used over time, then production stability is maintained, but commercial competitiveness decreases
Solution Approach 1:
The patent enables rapid parameter changes in hybrid corn varieties by selecting from inbred lines with different genetic compositions and trait profiles. Breeders can modify key parameters such as disease resistance, yield characteristics, and adaptability by combining different pre-characterized inbred lines, allowing quick development of competitive new varieties without sacrificing production stability
