Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new inbred corn lines is a slow and costly process, requiring expertise and numerous steps, and existing inbred parent corn lines lose commercial competitiveness over time, necessitating the need for improved germplasm with enhanced yield, disease resistance, and trait technologies.
Innovation Solution
The introduction of the inbred corn line 0BYIH1358, which is a new yellow dent inbred corn line with specific physiological and morphological characteristics, and methods for producing and treating seeds to enhance resistance to stress conditions, including the use of agricultural chemicals and breeding techniques such as pedigree breeding, backcrossing, haploid breeding, and mutation breeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional inbreeding techniques are used to develop new inbred corn lines, then new germplasm with desirable traits can be obtained, but the process is slow and costly
Solution Approach 1:
The patent applies preliminary action by pre-establishing a comprehensive set of molecular markers across the corn genome before breeding operations. This marker framework is prepared in advance to enable rapid genotype identification and selection during the breeding process, eliminating the need for time-consuming phenotypic evaluation and accelerating the development of new inbred lines while maintaining genetic precision
2Stability of the object's composition
If extensive inbreeding is performed to achieve homozygosity, then stable inbred lines are produced, but line vigor decreases
Solution Approach 1:
The patent implements feedback by continuously monitoring genotype data through molecular markers during the inbreeding process. This real-time genetic information feeds back to breeders, allowing them to track homozygosity progression and make informed decisions about when to terminate inbreeding or introduce genetic diversity, thereby maintaining line vigor while achieving sufficient genetic stability for practical use
3Productivity
If existing inbred parent corn lines are used over time, then production is maintained, but they lose commercial competitiveness
Solution Approach 1:
The patent applies dynamics by creating a flexible, modular breeding system using molecular markers that allows continuous updating and refinement of inbred lines. Breeders can dynamically adjust selection criteria, introduce new genetic variants, and rapidly develop improved germplasm in response to changing market demands and performance requirements, keeping corn lines commercially competitive over time while maintaining production stability
