Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheat breeding techniques face challenges in combining desirable traits such as high seed yield, disease resistance, drought tolerance, and improved agronomic characteristics in a single wheat variety, while also ensuring genetic stability and adaptability across different growing conditions.
Innovation Solution
The development of the wheat variety M14C1030, which involves genetic modification through transgenic techniques and traditional breeding methods to introduce specific traits like herbicide resistance, disease resistance, and improved yield potential, using methods like CRISPR-Cas system, zinc-finger nucleases, and tissue-specific promoters, while maintaining the variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to combine desirable traits, then genetic stability is maintained, but the ability to introduce new traits such as herbicide resistance and improved yield potential is limited
Solution Approach 1:
The patent employs CRISPR-Cas system as an intermediary tool to facilitate precise genetic modifications. This system acts as a mediator between the desired traits and the wheat genome, enabling the introduction of new characteristics (such as herbicide resistance and improved yield potential) without requiring complex multi-generation breeding processes. The CRISPR-Cas system simplifies the breeding process by directly editing the genome rather than relying on traditional cross-breeding methods.
2Productivity
If multiple breeding steps are implemented to achieve desired traits, then trait combination is improved, but the time required for development increases
Solution Approach 1:
The patent applies preliminary action by using CRISPR-Cas system to pre-modify the wheat genome before traditional breeding steps are completed. This allows desirable traits to be introduced and stabilized in fewer generations, significantly reducing the time required for breeding development while maintaining high productivity in trait combination efficiency.
3Reliability
If genetic modification techniques are used to introduce specific traits, then herbicide resistance and disease resistance are improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent replaces complex mechanical breeding processes with molecular biology techniques. Instead of using traditional cross-breeding and selection methods to achieve disease resistance and herbicide resistance, the CRISPR-Cas system directly edits the genome to introduce these traits. This substitution of mechanical breeding processes with molecular tools simplifies the overall breeding program while improving reliability of disease resistance.
