Soybean Variety Trait Stacking for Yield and Herbicide Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean varieties lack improved combinations of traits such as higher seed yield, disease resistance, insect resistance, drought tolerance, and herbicide resistance, which are essential for maximizing grain production and meeting the demands of food and animal feed.
Innovation Solution
Development of the novel soybean variety 01098371, which incorporates genetic modifications and single locus conversions for herbicide resistance, disease resistance, and improved agronomic qualities through breeding and genetic engineering techniques, including the use of engineered nucleases for genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional soybean varieties are used, then current germplasm traits are maintained, but seed yield, disease resistance, and herbicide resistance remain insufficient
Solution Approach 1:
The breeding program segmented the improvement of soybean varieties into distinct trait components: disease resistance (Phytophthora, nematode), herbicide resistance (glyphosate, glufosinate, dicamba), and yield characteristics. Each trait was targeted through specific genetic modifications and selective breeding, allowing independent optimization of multiple characteristics simultaneously.
Solution Approach 2:
The patent combines multiple resistance traits and improved agronomic characteristics into a single composite soybean variety (01098371). This composite approach integrates disease resistance, insect resistance, drought tolerance, and herbicide resistance into one variety, creating a multi-functional germplasm that addresses multiple limitations simultaneously.
2Adaptability or versatility
If multiple resistance traits are combined in one variety, then overall crop performance improves, but breeding complexity increases
Solution Approach 1:
The soybean variety 01098371 is designed with universal adaptability across multiple stress conditions and agricultural practices. It simultaneously provides resistance to Phytophthora, soybean cyst nematode, and tolerance to glyphosate, glufosinate, and dicamba, making it universally applicable in diverse farming environments and reducing the need for multiple specialized varieties.
Solution Approach 2:
The breeding program performed preliminary actions by first identifying and selecting parental lines with specific resistance traits, then systematically combining them through controlled crosses. Genetic modifications were introduced in advance to establish desired traits before final variety development, streamlining the complex breeding process.
3Reliability
If genetic modifications are introduced for herbicide resistance, then herbicide tolerance improves, but potential off-target effects may occur
Solution Approach 1:
The patent introduces genetic modifications that alter specific biochemical parameters in the soybean plant to confer herbicide tolerance. These parameter changes include modified enzyme activities or receptor structures that specifically interact with glyphosate, glufosinate, or dicamba, allowing the plant to withstand these herbicides while maintaining normal physiological function and reducing off-target effects.
