Soybean Variety Trait Stacking for Yield and Resistance Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean varieties lack improved combinations of traits such as higher seed yield, disease resistance, herbicide tolerance, and nutritional quality, making it challenging to develop stable and high-yielding soybean varieties that meet agronomic and nutritional demands.
Innovation Solution
Development of the soybean variety 01106520, which includes genetic modifications for herbicide resistance, disease resistance, and improved nutritional quality, achieved through genetic transformation using engineered nucleases and single locus conversions, along with breeding methods like backcrossing and hybridization to enhance desired traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used, then variety development is straightforward, but improved combinations of traits (yield, disease resistance, herbicide tolerance, nutritional quality) cannot be achieved
Solution Approach 1:
The patent applies parameter changes by modifying the genetic composition of soybean varieties through engineered nucleases to achieve superior trait combinations. Specifically, the breeders used CRISPR/Cas9 and other nuclease technologies to create precise genetic modifications that confer herbicide tolerance, disease resistance, and improved nutritional quality simultaneously, thereby changing the genetic parameters of the soybean varieties to overcome the limitations of conventional breeding.
2Reliability
If genetic transformation using engineered nucleases is applied, then herbicide resistance and disease resistance are improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent replaces traditional mechanical breeding methods (manual crossing, selection, and hybridization) with engineered nuclease technology. This substitution allows for precise, targeted genetic modifications without the need for complex multi-generational crossing programs. The engineered nucleases directly edit the genome to introduce desired traits such as herbicide resistance and disease resistance, thereby reducing the overall complexity of the breeding process despite the sophistication of the molecular tools used.
3Productivity
If multiple traits are combined in a single variety, then agronomic performance is improved, but the difficulty of developing such varieties increases
Solution Approach 1:
The patent merges multiple desirable traits (herbicide tolerance, disease resistance, improved nutritional quality, and high yield) into single soybean varieties through engineered nuclease-mediated genetic modification. By combining these traits at the molecular level rather than through traditional hybridization, the patent achieves superior agronomic performance while streamlining the development process. The engineered nucleases enable simultaneous introduction of multiple traits through targeted genome editing, thereby reducing the complexity associated with combining multiple traits in conventional breeding.
