Hybrid Corn Variety CH010571 for Uniform Yield and Controlled Pollination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn breeding techniques struggle to develop hybrids with uniformity and stability, incorporating desirable traits such as yield, disease resistance, and drought tolerance, while maintaining genetic diversity and avoiding self-pollination.
Innovation Solution
The development of the hybrid corn variety CH010571, which includes cytoplasmic or nuclear factors for male sterility, genetic modifications for traits like herbicide resistance, and a method for controlled cross-pollination using emasculation and bagging techniques, along with genetic editing tools like CRISPR-Cas systems, to ensure uniformity and introduce desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional self-pollination breeding methods are used, then genetic stability is maintained, but yield and desirable traits are limited
Solution Approach 1:
The patent segments the breeding process into distinct phases: developing homozygous inbred parent lines through self-pollination to maintain genetic stability, then crossing these inbreds to produce hybrid offspring that exhibit heterosis for improved yield and traits. This segmentation allows each phase to optimize for its specific goal.
Solution Approach 2:
The patent changes the genetic composition parameter by crossing genetically uniform inbred lines (high homozygosity) to produce hybrids with high heterozygosity. This parameter change from homozygous parents to heterozygous offspring enables the expression of desirable hybrid traits and increased yield while maintaining control over the breeding process.
2Productivity
If cross-pollination is used to develop hybrid varieties, then yield and desirable traits are improved, but uniformity in germination and growth is reduced
Solution Approach 1:
The patent performs preliminary self-pollination and selection over multiple generations to develop uniform homozygous inbred parent lines before crossing. This preliminary action ensures that the parent lines are genetically uniform, which then translates to uniformity in the hybrid offspring's germination and growth characteristics.
Solution Approach 2:
The patent employs phenotypic and genotypic selection as feedback mechanisms during the development of inbred parent lines. By selecting plants that exhibit desired uniformity and trait expression, the breeding process ensures that the resulting hybrids will have consistent germination and growth characteristics.
3Adaptability or versatility
If multiple breeding populations are combined to develop new inbreds, then genetic diversity and desirable traits are increased, but breeding complexity and time are increased
Solution Approach 1:
The patent segments the complex breeding program into distinct components: developing separate inbred parent lines with specific desirable traits, then crossing these pre-developed lines. This segmentation manages complexity by handling one trait or characteristic at a time in each parent line rather than attempting to combine all traits simultaneously.
Solution Approach 2:
The patent performs preliminary development and stabilization of inbred parent lines before crossing. This preliminary action includes multiple generations of self-pollination and selection to establish uniform, stable lines with desired traits, which simplifies the subsequent crossing and hybrid development process.
4Stability of the object's composition
If inbred plants are developed through repeated selfing, then genetic uniformity is achieved, but time and generations required are increased
Solution Approach 1:
The patent initiates repeated self-pollination early in the breeding program to begin the process of achieving genetic uniformity in parent lines. By starting this process preliminarily and continuing it systematically through multiple generations, the patent efficiently develops uniform inbreds that serve as the foundation for hybrid development.
