Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding techniques face challenges in developing uniform corn hybrids with desirable traits such as high yield, disease resistance, and uniform germination, as they often result in unpredictable performance due to genetic non-uniformity among hybrid plants.
Innovation Solution
The development of the corn variety CV295879, which includes a cytoplasmic or nuclear factor for male sterility and additional heritable traits like herbicide tolerance and disease resistance, along with a process for producing hybrid seeds by crossing inbred plants to ensure genetic uniformity and desirable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding techniques are used to develop corn hybrids, then various desirable traits can be combined in a single variety, but the resulting hybrid plants show genetic non-uniformity leading to unpredictable performance
Solution Approach 1:
The patent applies homogeneity by developing highly inbred parental lines that are genetically uniform, ensuring that all hybrid plants produced from these parents have identical and predictable genotypes. This is achieved through extended self-pollination and selection processes that create homogeneous inbred populations, resolving the contradiction between trait combination and performance predictability.
2Stability of the object's composition
If self-pollination is used to develop homozygous inbred plants, then uniform true breeding progeny are produced, but the breeding process requires multiple generations and extensive selection time
Solution Approach 1:
The patent applies preliminary action by pre-developing and maintaining stocked inbred lines that have already undergone the time-consuming homozygization process. These pre-prepared inbreds can be immediately used for hybrid production without requiring repeated generations of self-pollination, thus achieving genetic uniformity while reducing the time required for each breeding cycle.
3Adaptability or versatility
If cross-pollination is used to produce hybrid plants, then genetic diversity is introduced, but the resulting population is non-uniform and performance becomes unpredictable
Solution Approach 1:
The patent resolves this contradiction by using highly homozygous inbred lines as parents, which ensures that despite the cross-pollination process introducing genetic recombination, all resulting hybrid plants have identical heterozygous genotypes. This produces a uniform F1 hybrid population with predictable performance, combining the benefits of cross-pollination genetics with population uniformity.
