Corn Variety CV651295 Breeding for Genetic Uniformity
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 CV651295, which includes a cytoplasmic or nuclear factor for male sterility and genetic modifications conferring traits like herbicide tolerance, disease resistance, and modified metabolism, along with a process for producing inbred and hybrid corn plants using specific crossing and tissue culture methods.
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 in a single variety, but the resulting hybrid plants exhibit genetic non-uniformity leading to unpredictable performance
Solution Approach 1:
The patent applies homogeneity by developing highly inbred parental lines that are genetically uniform and homozygous. This ensures that all hybrid plants produced from these parental lines exhibit consistent genetic composition and uniform performance, eliminating the genetic non-uniformity problem while maintaining the ability to combine multiple desirable traits through controlled crosses
2Stability of the object's composition
If self-pollination is used to develop uniform inbred plants, then genetic uniformity is achieved, but the breeding process requires multiple generations and extensive selection time
Solution Approach 1:
The patent applies preliminary action by pre-developing and maintaining a library of highly inbred, genetically uniform parental lines with known desirable traits. This preliminary preparation allows breeders to quickly create uniform hybrids through simple crosses without needing to perform multiple generations of selfing and selection for each new hybrid, significantly reducing the breeding cycle time while maintaining genetic uniformity
