Solution Overview
Problem
There is a need for stable, high-yielding corn hybrids that are agronomically sound to maximize ear or kernel production, addressing the challenge of developing superior parental lines for corn breeding.
Innovation Solution
The development of a novel inbred corn line, KW9FD1634, which includes methods for producing seeds, plants, and variants with specific morphological and physiological characteristics, utilizing mutagenesis techniques and transgenic approaches to introduce desired traits such as herbicide resistance, disease resistance, and improved nutritional quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional breeding methods are used to develop corn hybrids, then the breeding process is relatively simple and cost-effective, but the yield potential and agronomic performance are limited
Solution Approach 1:
The patent applies parameter changes by modifying genetic parameters through mutagenesis techniques (chemical, physical, or biological agents) to introduce novel variations in corn plants. This enables the development of hybrids with superior yield potential and agronomic traits that cannot be achieved through conventional breeding alone, directly addressing the productivity limitation while managing complexity through targeted genetic modification.
2Productivity
If superior parental lines are developed through extensive breeding, then hybrid yield and performance are improved, but the time and resources required for breeding increase
Solution Approach 1:
The patent implements preliminary action by pre-introducing desirable traits and performing selective breeding steps before hybrid development. Mutagenesis is applied early in the breeding process to create plants with pre-selected advantageous characteristics, reducing the time required for subsequent selection and breeding cycles. This allows for faster development of superior parental lines while maintaining high hybrid yield potential.
3Reliability
If mutagenesis and transgenic techniques are used to introduce desired traits, then disease resistance and nutritional quality are improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent uses intermediaries in the form of mutagenesis agents (chemical, physical, or biological) that mediate the introduction of desired traits into corn plants. These intermediaries facilitate the transfer of specific genetic characteristics for disease resistance and nutritional quality without requiring direct complex genetic engineering procedures, thereby improving reliability while managing breeding process complexity through indirect but effective means.
