Hybrid Corn CH810147 Breeding Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corn breeding techniques face challenges in developing uniform hybrid varieties with desirable traits such as high yield, disease resistance, and uniform germination due to genetic non-uniformity in cross-pollinated plants, requiring the development of stable inbred plants and specific breeding methods.
Innovation Solution
The development of the hybrid corn variety CH810147, which includes genetic loci for traits like male sterility, herbicide resistance, and disease resistance, utilizing cytoplasmic-male sterility and transgenes integrated at specific chromosomal locations, along with tissue culture methods for regenerating plants with consistent physiological and morphological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination is used to develop corn hybrids, then genetic diversity and trait combination are improved, but genetic uniformity and predictability of performance deteriorate
Solution Approach 1:
The breeding process is segmented into distinct phases: first developing homozygous inbred lines through self-pollination to ensure genetic uniformity, then crossing these standardized lines to introduce controlled genetic diversity. This segmentation allows each phase to optimize for its specific goal without compromising the other.
Solution Approach 2:
Homozygous inbred parent lines are developed and standardized before the hybrid crossing stage. This preliminary action of creating genetically uniform parents ensures that the subsequent cross-pollination produces predictable, uniform hybrids with consistent performance traits.
2Stability of the object's composition
If self-pollination is used to develop inbred lines, then genetic uniformity is improved, but genetic diversity and adaptability deteriorate
Solution Approach 1:
Self-pollination is used as a preliminary action to create genetically uniform inbred parent lines. Once these standardized parents are established, they serve as the foundation for hybrid development, where genetic diversity is then introduced through controlled crossing.
Solution Approach 2:
The breeding program segments the population into distinct inbred lines that are genetically uniform within themselves but genetically diverse across lines. This segmentation allows uniformity at the line level while maintaining diversity at the program level.
3Adaptability or versatility
If traditional breeding methods are used to combine multiple desirable traits, then trait variety is improved, but breeding time and complexity increase
Solution Approach 1:
Multiple desirable traits are incorporated into the inbred parent lines through preliminary breeding actions before the hybrid crossing stage. This allows the actual hybrid production to occur in a single crossing event rather than requiring multiple generations of selection and recombination.
Solution Approach 2:
The invention merges multiple trait combinations into standardized inbred parent lines that can then be crossed to produce hybrids with predetermined trait combinations. This merging of traits into parental lines accelerates the breeding process by consolidating what would otherwise require sequential development into parallel developments.
