Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding techniques face challenges in developing new inbred corn lines that maintain commercial competitiveness due to decreased vigor over time, requiring the development of improved germplasm with traits like early flowering, fast grain drydown, and high yields.
Innovation Solution
The introduction of the inbred corn line BE9513, which exhibits early flowering, fast grain drydown, and high yields, along with methods for producing and utilizing BE9513-derived plants through self-pollination, sib-pollination, and hybrid production, including seed treatment options for enhanced resistance to stress conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional inbreeding techniques are used to develop new inbred corn lines, then genetic uniformity and homozygosity are achieved, but plant vigor decreases over time
Solution Approach 1:
The patent applies parameter changes by introducing a specific inbred line BE9513 with optimized genetic parameters that maintain homozygosity while restoring vigor through selective breeding. The inbred line exhibits improved vigor parameters compared to traditional inbreds, achieving a balance between genetic stability and plant strength through controlled parameter modification in the breeding process.
2Stability of the object's composition
If inbreeding is continued to achieve higher homozygosity, then genetic purity is improved, but yield and performance deteriorate
Solution Approach 1:
The patent resolves this contradiction by introducing inbred line BE9513 with modified genetic parameters that break the traditional trade-off between purity and productivity. Through selective breeding and parameter optimization, the inbred line achieves high genetic purity while simultaneously maintaining high yield potential, eliminating the need to choose between purity and productivity.
Solution Approach 2:
The patent uses copying by developing inbred line BE9513 as a superior genetic model that can be replicated and used as a parent line in hybrid production. This copying approach allows the desirable traits of high purity and high yield to be propagated across multiple generations and hybrid combinations, solving the productivity-purity contradiction through genetic replication.
3Productivity
If existing inbred lines are used for hybrid production, then commercial competitiveness is maintained, but resistance to insects, weeds, and diseases decreases
Solution Approach 1:
The patent applies composite materials by creating inbred line BE9513 with composite genetic traits that combine multiple resistance characteristics alongside high yield potential. The inbred line integrates diverse genetic components that provide both commercial competitiveness and enhanced reliability through multi-trad resistance to insects, weeds, and diseases.
