Soybean Germplasm Pre-Stacking for Stable High-Yield Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars lack improved traits such as higher seed yield, disease resistance, drought tolerance, and altered fatty acid profiles, which are essential for enhancing agricultural productivity and nutritional value.
Innovation Solution
Development of a new soybean cultivar (24151891) with specific genetic modifications and introgression of transgenic traits, including herbicide tolerance and disease resistance, through methods like mutagenesis and transformation, combined with traditional breeding techniques to enhance desirable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding techniques are used to develop new soybean cultivars, then genetic diversity is maintained, but the development process takes 6-12 years and requires multiple generations of crossing and selection
Solution Approach 1:
The patent applies preliminary action by pre-modifying parental germplasm with specific traits (disease resistance, yield characteristics, fatty acid profiles) through transformation or mutagenesis before crossing. This allows the F1 generation to directly express improved traits without requiring multiple generations of backcrossing and selection, thereby reducing the breeding cycle from 6-12 years to a single generation while maintaining genetic stability through controlled parental selection
2Manufacturing precision
If multiple generations of crossing and selection are performed to combine desirable traits, then trait combination precision is improved, but resource consumption and process complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-combining multiple desirable traits into single parental lines through prior transformation events or mutagenesis. This allows the F1 generation to inherit a pre-packaged combination of traits (e.g., disease resistance + yield + fatty acid profile) in a single cross, eliminating the need for complex multi-generation breeding programs and reducing process complexity while maintaining trait combination accuracy
Solution Approach 2:
The patent applies universality by developing parental germplasm that simultaneously possesses multiple desirable traits (disease resistance, yield improvement, altered fatty acid profiles) through single transformation events introducing multiple genes or through coordinated mutagenesis. This multi-functional parental material enables single-generation breeding to achieve what traditionally required multiple generations, simplifying the breeding process while maintaining precise trait combination
3Stability of the object's composition
If conventional soybean cultivars are used, then agronomic stability is maintained, but seed yield, disease resistance, and nutritional value remain suboptimal
Solution Approach 1:
The patent applies parameter changes by modifying specific genetic parameters in soybean cultivars through transformation (introducing foreign genes for disease resistance or trait enhancement) and mutagenesis (inducing mutations to alter fatty acid profiles or yield characteristics). These controlled parameter changes at the molecular level enable simultaneous improvement of productivity (yield, nutrition) while maintaining agronomic stability through selection of stable transgenic or mutant lines that perform consistently across environments
