Inbred Corn Line BB86 Breeding Program
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new corn inbred lines is a time-consuming and unpredictable process due to the complexity of inheritance and environmental factors, making it challenging to identify genetically superior plants with desirable traits such as high yield, disease resistance, and adaptability.
Innovation Solution
The introduction of the inbred corn line BB86, which is a yellow dent corn with superior characteristics, including high yield potential, disease tolerance, and adaptability to various regions, along with methods for producing hybrid seeds and transformed plants with desired traits like male sterility, herbicide resistance, and improved nutritional quality through backcrossing and genetic engineering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop new corn inbred lines, then genetic diversity and adaptability can be improved, but the process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by creating a structured breeding program that pre-plans multiple generations of self-pollination and selection before final hybrid development. The inbred line BB86 undergoes systematic selection and evaluation across multiple generations (F2, F3, F4) with predetermined breeding objectives, allowing the breeding process to be more predictable and time-efficient compared to conventional random mating approaches
2Ease of operation
If selection is based on phenotypic observations alone, then identification of superior plants is simplified, but genetic superiority cannot be reliably determined due to environmental factors
Solution Approach 1:
The patent implements feedback through replicated evaluations and multiple observations of plant performance across different environments and generations. The breeding program systematically records phenotypic data from multiple replications and uses this feedback to refine selection criteria, gradually separating genetic effects from environmental noise to achieve more precise identification of genetically superior plants
3Adaptability or versatility
If multiple breeding methods are employed to address different traits, then comprehensive trait improvement is achieved, but the complexity of inheritance becomes more difficult to manage
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases and generations, each focused on specific traits or objectives. The process is segmented into F2 generation selection for basic yield traits, F3 generation for disease resistance, and F4 generation for agronomic quality, making the complex inheritance management more systematic and manageable through staged approach
