Inbred Corn Line 103B159 for Hybrid Yield and Disease Resistance
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 to enhance yield production and protect against insects, weeds, and diseases.
Innovation Solution
The introduction of the inbred corn line 103B159, which is a new yellow dent inbred corn line that can be used for self-pollination or sib-pollination, and methods for producing hybrid corn plants by crossing 103B159 with other inbred or hybrid corn plants, including techniques for controlling male fertility and using transgenic approaches to introduce desirable traits.
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 developing and preserving a library of inbred corn lines with predetermined desirable traits (yield, disease resistance, adaptability) before they are needed for hybrid production. This pre-prepared germplasm library eliminates the need for time-consuming traditional inbreeding processes when new hybrids need to be developed, as breeders can directly utilize these pre-characterized lines.
2Productivity
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 parameter changes by systematically varying and selecting for multiple performance parameters (yield, disease resistance, adaptability to different environments) when developing new inbred lines. This ensures that new germplasm maintains high productivity while adapting to changing commercial requirements and environmental conditions, preventing the stagnation and loss of competitiveness that occurs with长期使用 of existing lines.
3Adaptability or versatility
If traditional breeding methods are used, then corn plants can be improved, but extensive breeding work is required to maintain competitiveness
Solution Approach 1:
The patent applies copying by creating and replicating successful inbred lines that have demonstrated superior performance characteristics. Once an inbred line with desirable traits is developed, it can be copied and propagated to produce multiple generations of hybrid seed, eliminating the need to repeatedly perform extensive breeding work. This replication strategy maintains plant performance improvement while reducing breeding complexity.
