Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties is a time-consuming process that requires years to combine desirable traits such as disease resistance, drought tolerance, and high yield, posing challenges in efficiently producing stable and agronomically sound maize varieties.
Innovation Solution
The development of a novel maize variety, 1PRME66, with specific traits introduced through backcross conversion, genetic manipulation, and transformation, including cytoplasmic male sterility and heritable traits like herbicide tolerance and disease resistance, facilitated by crossing and tissue culture techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine desirable traits, then the maize variety achieves desired traits such as disease resistance and high yield, but the development process takes six to twelve years
Solution Approach 1:
The patent employs preliminary action by using molecular marker technology to identify and select plants with desired traits at early stages of breeding, rather than waiting for traditional phenotypic expression. This allows breeders to pre-select individuals carrying specific genes for disease resistance, yield, and other desirable characteristics, significantly accelerating the breeding process while maintaining trait stability.
Solution Approach 2:
The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based selection. Instead of visually assessing plant traits after they manifest, the invention uses DNA markers to detect the presence of desired genes at the molecular level, enabling earlier and more accurate selection of breeding candidates.
2Adaptability or versatility
If multiple desirable traits are combined through traditional breeding, then the maize variety achieves comprehensive improvement, but the process complexity increases
Solution Approach 1:
The patent applies segmentation by breaking down the complex breeding process into manageable components using molecular markers for each specific trait. Each desired trait (disease resistance, yield, drought tolerance) can be tracked and selected for independently through specific molecular markers, allowing breeders to systematically combine multiple traits without being overwhelmed by the overall complexity.
Solution Approach 2:
The patent implements feedback mechanisms through molecular marker analysis that provides real-time information about the genetic composition of breeding plants. This feedback allows breeders to make informed decisions at each generation, tracking the accumulation of desired traits and adjusting breeding strategies accordingly, thereby managing program complexity through systematic monitoring and control.
