Corn Variety CV112211 Breeding for Genetic Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding methods 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 CV112211, which is an inbred corn plant with specific physiological and morphological characteristics, including the option for cytoplasmic or nuclear factors that confer male sterility or herbicide tolerance, insect resistance, and other desirable traits, along with a process for producing hybrid seeds by crossing CV112211 with other inbred plants to achieve uniform and stable genetic complements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional corn breeding methods are used to develop hybrids, then various desirable traits can be combined, but genetic non-uniformity among hybrid plants results in unpredictable performance
Solution Approach 1:
The patent employs homozygous inbred plants as parental lines, which are genetically uniform and true-breeding. This homogeneity at the parental level ensures that all F1 hybrid progeny receive identical genetic combinations, eliminating genetic non-uniformity and achieving predictable performance 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 process requires multiple generations and extensive breeding time
Solution Approach 1:
The patent utilizes pre-developed homozygous inbred parental lines that have already undergone multiple generations of self-pollination and selection to achieve genetic uniformity. By starting with these pre-prepared uniform parents, the method achieves genetic stability in the F1 generation without requiring the recipient to perform the time-consuming multi-generational inbreeding process themselves
3Productivity
If cross-pollination is used to produce hybrid plants, then hybrid vigor is achieved, but genetic non-uniformity makes performance unpredictable
Solution Approach 1:
The patent ensures that both parental lines are homozygous and genetically uniform, so that cross-pollination between them produces F1 hybrids that are all genetically identical to one another. This uniformity in the parental genotypes translates to uniformity in the hybrid progeny, achieving both hybrid vigor and consistent, predictable performance across all plants
