Inbred Corn Line BC136 Breeding Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new corn cultivars is a time-consuming process due to the unpredictability of genetic traits in conventional breeding methods, which requires extensive research and resources to identify superior inbred lines with desirable characteristics such as high yield, disease resistance, and adaptability to various environments.
Innovation Solution
The introduction of the inbred corn line BC136, which is specifically adapted for the East, Central, South, and Western regions of the US Corn Belt, offering high yield potential, uniformity, and stability, along with methods for producing hybrid seeds and transformed lines with desired traits like male sterility, herbicide resistance, and improved nutritional quality through backcrossing and genetic modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop new corn cultivars, then genetic diversity and adaptability can be achieved, but the process becomes time-consuming and resource-intensive due to unpredictability of genetic traits
Solution Approach 1:
The patent applies preliminary action by developing inbred line BC136 with pre-established desirable traits including high yield potential, uniformity, and stability before hybridization. This pre-prepared inbred line reduces the time required for subsequent breeding steps while maintaining adaptability across different regions of the US Corn Belt
Solution Approach 2:
The patent utilizes parameter changes by modifying genetic parameters through controlled backcrossing and selection processes. The inbred line BC136 was developed through systematic changes in genetic composition, achieving optimal balance between yield, uniformity, and adaptability parameters that conventional breeding alone would take much longer to achieve
2Measurement precision
If extensive replication and evaluation are conducted to identify superior inbred lines, then measurement precision of genetic worth is improved, but the complexity and resource requirements increase
Solution Approach 1:
The patent applies copying by creating multiple replicated copies of inbred line BC136 for systematic evaluation across different locations and environments. This standardized copying approach allows for precise measurement of genetic performance while reducing program complexity through consistent replication protocols rather than ad hoc breeding designs
Solution Approach 2:
The inbred line BC136 demonstrates universality by performing consistently across multiple functions and environments - it serves as a reliable parent for hybrid development in various regions of the US Corn Belt, providing both yield contribution and uniformity across diverse growing conditions, thereby reducing the need for environment-specific breeding programs
