Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in plant breeding is to develop high-yielding, agronomically sound dent corn hybrids with desirable traits such as disease resistance, drought tolerance, and uniformity, which is hindered by the unpredictability of genotype interactions with environmental conditions and the complexity of selecting suitable inbred parental lines.
Innovation Solution
The development of an inbred dent corn line, I10516, with specific agronomic characteristics, including disease resistance and stability, through traditional breeding and potential genetic marker-assisted selection, allowing for the production of hybrid maize with enhanced traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop dent corn hybrids, then various desirable traits can be combined in a single variety, but the process is hindered by the unpredictability of genotype interactions with environmental conditions and the complexity of selecting suitable inbred parental lines
Solution Approach 1:
The patent introduces inbred line I10516 as an intermediary parental line that mediates the breeding process. This specific inbred line serves as a reliable genetic foundation that simplifies the selection process by providing predictable performance and consistent trait expression when crossed with other inbred lines, thereby reducing the overall complexity of the breeding program while maintaining the ability to combine multiple desirable traits.
2Productivity
If multiple inbred parental lines are evaluated to find suitable combinations, then high-yielding hybrids with desirable traits can be developed, but the time and resources required for evaluation increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-developing and characterizing inbred line I10516 with known desirable traits and consistent performance characteristics before using it in hybrid development programs. This preliminary characterization allows breeders to skip extensive evaluation phases and directly utilize the inbred line in crossing programs, significantly reducing the time required to develop high-yielding hybrids while maintaining productivity.
3Productivity
If inbred lines with high yield potential are selected, then hybrid productivity is improved, but the stability and consistency of performance across different environments may be compromised
Solution Approach 1:
The patent utilizes parameter changes by developing inbred line I10516 with specific genetic parameters that optimize both yield potential and environmental stability. The inbred line was developed through selective breeding to achieve optimal parameter values for traits such as disease resistance, plant architecture, and yield components, creating a balanced genotype that maintains high productivity across varying environmental conditions rather than maximizing single traits.
