Inbred Corn Line D054245 Breeding Methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new inbred corn plants and hybrid corn varieties is a slow and costly process, requiring expertise and numerous steps, and existing inbred parent corn lines lose their commercial competitiveness over time, necessitating the need for improved germplasm with enhanced traits for yield, disease resistance, and environmental adaptability.
Innovation Solution
The introduction of the inbred corn line D054245, which is a new yellow dent inbred corn line with specific physiological and morphological characteristics, and methods for producing inbred and hybrid corn plants through self-pollination, sib-pollination, and cross-pollination, along with techniques such as backcrossing, haploid breeding, and mutation breeding to introduce desirable traits, and the use of transgenic approaches to enhance resistance and adaptability.
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 can be obtained, but the process is slow and costly
Solution Approach 1:
The patent applies preliminary action by establishing a systematic breeding program framework in advance, including predefined crossing schemes, selection criteria, and evaluation protocols. This allows the breeding process to proceed efficiently through multiple generations without repeated decision-making delays, accelerating the development of new inbred lines while maintaining rigorous selection standards.
2Reliability
If extensive breeding steps are performed to improve corn traits, then yield and disease resistance can be enhanced, but the commercial competitiveness is lost over time
Solution Approach 1:
The patent implements continuity of useful action by maintaining ongoing breeding programs that continuously produce new inbred lines with improved traits. Rather than periodic breeding efforts, the system operates continuously through multiple generations, constantly refreshing the germplasm pipeline. This ensures that new lines with enhanced disease resistance and yield are continuously introduced to maintain commercial competitiveness.
3Productivity
If multiple breeding techniques are applied to enhance traits, then corn plant performance can be improved, but the process complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding process into distinct, manageable stages: initial crossing, F1 generation evaluation, backcrossing phases, and final inbred line development. Each stage has specific objectives and selection criteria, allowing complex trait enhancement to be achieved through a series of simpler, well-defined steps rather than attempting all modifications simultaneously.
