Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheat breeding methods 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 maintaining genetic stability and uniformity.
Innovation Solution
The development of the wheat variety 6PYMG52B, which involves genetic modification and locus conversion through transgenic techniques, including CRISPR/Cas system, to introduce traits like herbicide resistance, disease resistance, and improved nutritional quality, along with traditional breeding methods like backcrossing and selection to ensure stability and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to combine multiple desirable traits, then genetic diversity increases, but breeding time and complexity increase significantly
Solution Approach 1:
The patent replaces traditional mechanical breeding methods (crossing, selection, and recombination over multiple generations) with molecular biology techniques including gene cloning, transformation vectors, and direct gene transfer methods. This substitution enables precise introduction of desirable traits without the time-consuming process of traditional hybridization and selection, reducing breeding time from years to months while achieving the same genetic combination goals.
2Adaptability or versatility
If multiple traits are combined through conventional breeding, then trait diversity improves, but genetic stability and uniformity decrease
Solution Approach 1:
The patent applies local quality by introducing specific desirable traits through targeted gene transformation at particular genomic locations, rather than through global genetic recombination. Each desired trait (disease resistance, drought tolerance, nutritional quality) is introduced independently through molecular techniques, allowing precise control over which traits are combined while maintaining the genetic stability and uniformity of the base variety. This enables trait diversity without compromising genetic composition stability.
3Manufacturing precision
If genetic modification techniques are used to introduce specific traits, then breeding precision improves, but regulatory and public acceptance challenges increase
Solution Approach 1:
The patent extracts and utilizes naturally occurring genes and genetic elements that already exist in wheat or related species, rather than introducing entirely foreign genes. By using endogenous genes, gene families, and naturally occurring genetic sequences, the patent achieves precise trait introduction while minimizing regulatory hurdles and public acceptance issues associated with transgenic organisms. This extraction approach maintains breeding precision while reducing the complexity of regulatory approval processes.
