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 CV581972, which is a homozygous inbred line with specific traits like male sterility, herbicide tolerance, and disease resistance, achieved through backcrossing and genetic transformation techniques, ensuring uniformity and stability in progeny plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional corn breeding techniques are used, then corn varieties can be developed with desirable traits, but the performance becomes unpredictable due to genetic non-uniformity among hybrid plants
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 preliminary inbreeding process ensures genetic uniformity and stability in the parental lines, which then produce predictable and uniform hybrid progeny, resolving the issue of performance unpredictability caused by genetic non-uniformity.
Solution Approach 2:
The patent implements homogeneity by creating homozygous inbred lines where all individuals have identical genotypes at all loci. This genetic homogeneity within inbred lines ensures that when these lines are crossed to produce hybrids, the resulting hybrid population is uniform and predictable, eliminating the genetic non-uniformity that causes performance variability.
2Stability of the object's composition
If homozygous inbred plants are developed through multiple generations of selfing, then uniformity is achieved, but the breeding process becomes time-consuming and complex
Solution Approach 1:
The patent uses preliminary action by establishing homozygous inbred lines through multiple generations of self-pollination and selection before the hybrid development stage. This preliminary inbreeding, while time-consuming, creates genetically uniform parental lines that can then be crossed to produce uniform hybrids, making the overall breeding process efficient despite the initial time investment.
Solution Approach 2:
The patent applies parameter changes by monitoring and selecting for specific phenotypic and genotypic parameters across multiple generations. By changing and selecting for desired traits at each generation, the breeding process efficiently achieves homozygosity and uniformity without requiring unnecessary time, optimizing the breeding cycle duration.
3Adaptability or versatility
If cross-pollination is used to create hybrid plants, then genetic diversity is introduced, but uniformity and predictability of performance are reduced
Solution Approach 1:
The patent applies preliminary action by first developing homozygous inbred lines with specific desirable traits through multiple generations of self-pollination. These uniform inbred lines are then crossed to create hybrids. The preliminary inbreeding ensures that the parental lines are genetically stable, so the resulting hybrids, while diverse, remain uniform and predictable in their performance.
Solution Approach 2:
The patent implements local quality by introducing genetic diversity only where needed through controlled cross-pollination between specific inbred lines, while maintaining homozygosity and uniformity within each parental line. This localized approach to crossing allows genetic diversity to be introduced in a controlled manner that preserves overall progeny uniformity and predictability.
