Corn Variety CV093813 Breeding for Genetic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corn breeding aims to combine desirable traits like yield, disease resistance, and uniformity, but existing methods struggle to develop stable inbred plants with predictable performance due to genetic non-uniformity from cross-pollination, leading to unpredictable hybrid traits.
Innovation Solution
The development of the corn variety CV093813, which includes a cytoplasmic or nuclear factor for male sterility and specific genetic loci conferring traits like herbicide tolerance and disease resistance, along with a process for producing inbred and hybrid seeds through controlled pollination and backcrossing techniques, ensures genetic stability and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination is used to combine desirable traits from different plants, then genetic diversity and trait combination are improved, but genetic non-uniformity and unpredictable hybrid performance occur
Solution Approach 1:
The patent applies preliminary action by developing homozygous inbred lines through multiple generations of self-pollination and selection before creating hybrids. This pre-establishes genetic uniformity and stability in the parent lines, ensuring that when they are crossed, the hybrid performance is predictable and reliable, thus resolving the contradiction between trait combination capability and performance predictability.
2Stability of the object's composition
If self-pollination is used to develop homozygous inbred plants, then genetic uniformity and stability are improved, but the ability to combine diverse traits is reduced
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct phases: first developing homozygous inbred lines through self-pollination to achieve genetic uniformity, then creating hybrids by crossing these inbreds to combine diverse traits. This segmentation allows each phase to optimize for its specific goal, resolving the contradiction between genetic stability and trait diversity.
3Stability of the object's composition
If multiple generations of breeding are conducted to achieve homozygosity, then genetic stability is improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies feedback by implementing selection processes at each generation where plants are evaluated for desired traits and uniformity. This feedback mechanism allows breeders to identify and select the most promising lines early, accelerating the path to homozygosity and reducing the overall breeding time while maintaining genetic stability.
