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 into a single variety, while maintaining genetic stability and uniformity.
Innovation Solution
The development of the wheat variety PMWH80242964, which involves genetic transformation, genome editing, and backcrossing to introduce specific traits like herbicide resistance, disease resistance, and improved agronomic characteristics, along with methods for producing hybrid seeds and plants that express these traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wheat breeding methods are used to combine multiple desirable traits, then the variety can achieve higher seed yield and disease resistance, but the genetic stability and uniformity of the variety deteriorates
Solution Approach 1:
The patent applies genetic transformation and genome editing techniques to precisely modify specific genetic parameters rather than relying on traditional cross-breeding. This allows for the introduction of desirable traits (herbicide resistance, disease resistance, improved agronomic characteristics) while maintaining the overall genetic stability and uniformity of the wheat variety through targeted molecular changes rather than extensive genetic recombination
2Manufacturing precision
If genetic transformation and genome editing are used to introduce specific traits, then the precision of trait introduction is improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent replaces traditional mechanical breeding methods (cross-pollination, selection, and hybridization) with molecular biology techniques such as genetic transformation and genome editing. This substitution enables precise introduction of specific traits at the molecular level, achieving high precision in trait introduction while the patent systematically manages the increased process complexity through structured breeding protocols and regulatory compliance frameworks
3Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the agronomic characteristics are improved, but the difficulty of maintaining uniformity across the variety increases
Solution Approach 1:
The patent introduces multiple desirable traits (herbicide resistance, disease resistance, improved agronomic characteristics) as localized, independent genetic modifications rather than through extensive cross-breeding. Each trait is introduced through targeted genetic transformation or genome editing at specific loci, allowing for precise control and independent verification of each trait's uniformity across the variety population
