Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn breeding techniques struggle to combine desirable traits such as yield, disease resistance, and uniformity in a single hybrid variety, often requiring extensive selection and cross-pollination methods that are inefficient and time-consuming.
Innovation Solution
Development of the hybrid corn variety CH010431, which incorporates genetic modifications and cytoplasmic traits like male sterility, herbicide resistance, and disease resistance through methods like backcrossing and genome editing, ensuring uniformity and desirable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional self-pollination and phenotypic selection methods are used for corn breeding, then breeders can select for desirable traits, but the process becomes extremely time-consuming and inefficient
Solution Approach 1:
The patent replaces traditional mechanical phenotypic selection with molecular marker-assisted selection. Breeders use DNA markers to identify and select plants with desired genetic traits at the molecular level, eliminating the need for time-consuming phenotypic observation and manual selection processes across multiple generations.
Solution Approach 2:
The patent introduces molecular markers as intermediaries between the genotype and phenotype. These markers serve as detectable indicators that allow breeders to indirectly select for desirable traits without waiting for phenotypic expression, significantly accelerating the breeding process.
2Adaptability or versatility
If extensive cross-pollination and evaluation of multiple inbred plants are performed to develop hybrid varieties, then desirable traits can be combined, but the device complexity and breeding program complexity increase
Solution Approach 1:
The patent implements feedback mechanisms through molecular marker analysis at various stages of the breeding process. By continuously monitoring the genetic composition of breeding populations and individual plants, breeders can make informed decisions about which plants to advance, cross, or discard, streamlining the complex process of combining multiple desirable traits.
Solution Approach 2:
The patent segments the complex breeding program into distinct molecular marker-guided selection steps. Instead of managing complexity through extensive phenotypic evaluation, the breeding process is divided into manageable stages where specific marker sets are used to select for specific traits, making the overall program more controllable and efficient.
3Manufacturing precision
If traditional breeding methods are used to achieve uniformity in germination, stand establishment, and growth, then phenotypic uniformity can be selected, but the manufacturing precision and consistency of traits are insufficient
Solution Approach 1:
The patent replaces phenotypic selection for uniformity with molecular marker-based genotypic selection. By selecting plants with identical or highly similar genetic profiles at the marker level, breeders achieve precise uniformity in germination, stand establishment, and growth traits without relying on imprecise phenotypic observations.
