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 uniformity, as they often result in unpredictable performance due to genetic non-uniformity among hybrid plants.
Innovation Solution
The development of the corn variety CV353100, 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 conventional corn breeding techniques are used to develop hybrids, then various desirable traits can be combined, but genetic non-uniformity results in unpredictable performance
Solution Approach 1:
The patent applies homogeneity by developing highly inbred corn lines (9-10 generations of self-pollination) to achieve genetic uniformity within each parental line. This ensures that all plants in a hybrid population receive identical genetic material from each parent, eliminating the genetic non-uniformity that causes unpredictable performance while preserving the ability to combine multiple desirable traits through controlled crossing of these uniform lines.
2Manufacturing precision
If self-pollination is used to develop uniform inbred plants, then genetic uniformity is achieved, but the process requires extensive generations and time
Solution Approach 1:
The patent applies preliminary action by pre-developing and maintaining a library of highly inbred, genetically uniform corn lines before hybrid production is needed. These pre-established inbred lines can be immediately crossed to produce uniform hybrids, eliminating the need to perform lengthy self-pollination sequences (9-10 generations) at the time of hybrid production. The preliminary development of uniform parental lines enables rapid response to market demands while maintaining genetic precision.
3Reliability
If cross-pollination is used to produce hybrid corn, then uniform hybrids are obtained, but self-pollination control is difficult to prevent
Solution Approach 1:
The patent applies the taking out principle by physically removing the male reproductive organs (tassels) from female parent plants before pollination. This emasculation process extracts the source of unwanted self-pollination, ensuring that female plants can only receive pollen from intended male parent plants. This simple mechanical intervention effectively prevents self-pollination and maintains hybrid uniformity without requiring complex control systems.
