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 times, as they often result in unpredictable performance due to genetic non-uniformity among hybrid plants.
Innovation Solution
The development of the corn variety CV360779, which includes specific morphological and physiological characteristics, such as cytoplasmic male sterility and added heritable traits like herbicide tolerance and disease resistance, along with a process for producing hybrid seeds and plants using this variety to ensure genetic stability and desirable traits.
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 inbred corn lines that are genetically uniform and homozygous at almost all gene loci. This ensures that all plants in the breeding population have identical genetic makeup, eliminating the genetic non-uniformity that causes unpredictable performance in conventional hybrid breeding. The inbred lines serve as uniform parental stocks that consistently produce the same progeny when crossed.
2Stability of the object's composition
If self-pollination is used to develop uniform inbred plants, then genetic uniformity is achieved, but time to develop stable lines increases
Solution Approach 1:
The patent employs preliminary action by establishing and maintaining a library of pre-developed inbred corn lines with known genetic characteristics before actual hybrid breeding begins. These inbred lines are developed in advance through self-pollination and selection, so that when breeders need parental stocks for creating new hybrids, uniform, genetically stable lines are already available, significantly reducing the time required for the breeding process.
3Adaptability or versatility
If cross-pollination is used to create hybrid plants, then genetic diversity is increased, but uniformity among hybrid plants decreases
Solution Approach 1:
The patent resolves this contradiction by using homogeneous inbred lines as parental stocks for cross-pollination. Because both parent lines are genetically uniform and homozygous, their F1 hybrid progeny inherit a consistent set of alleles from each parent, resulting in uniform hybrid plants. This approach allows the benefits of cross-pollination (genetic diversity combining traits from two parents) while maintaining uniformity because the parental genomes themselves are uniform.
4Reliability
If extensive breeding populations are evaluated to find superior inbreds, then desirable traits can be identified, but resource requirements and complexity increase
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct segments: (1) development and maintenance of individual inbred lines, (2) evaluation of specific crosses between predetermined inbred lines, and (3) selection of superior hybrids. This segmentation allows breeders to systematically evaluate smaller, manageable populations at each stage rather than overwhelming breeding populations all at once, reducing overall program complexity while maintaining thorough evaluation of desirable traits.
