Solution Overview

Problem

Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved fatty acid profiles, while existing methods face challenges in efficiently combining these traits in a single variety.

Innovation Solution

The development of a novel soybean variety, XB35AX13, which is the result of careful breeding and selection, combining traits like resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a process involving backcrossing and genetic marker-assisted breeding to introduce desired traits and loci.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine multiple desirable traits, then the variety achieves stability and uniformity in traits, but the breeding process becomes time-consuming and resource-intensive

Engineering Contradiction:
Improvetrait stabilityVSAvoidbreeding duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs molecular marker-assisted selection (MAS) which provides feedback on the genetic composition of breeding lines at the DNA level. This allows breeders to track the inheritance of multiple desirable traits simultaneously and make informed selection decisions, significantly reducing the time required to develop stable varieties compared to traditional phenotypic selection methods.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical/phenotypic breeding methods with molecular biology-based techniques. Instead of relying on observable traits and manual selection, the invention uses DNA marker analysis to identify and select plants with desired genetic combinations, accelerating the breeding process while maintaining trait stability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple traits are combined in a single variety through breeding, then the variety achieves improved agronomic characteristics, but the complexity of the breeding program increases

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the breeding program into distinct phases: initial cross-breeding to introduce diverse traits, followed by molecular marker-assisted selection to systematically track and combine specific desirable traits. This segmentation allows complex multi-trait breeding to be managed through standardized, repeatable steps rather than attempting to manage all traits simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent develops a universal molecular marker system that can simultaneously track multiple different traits (disease resistance, yield components, quality attributes) using the same analytical framework. This multi-functional approach simplifies the breeding program by providing a unified method for selecting diverse trait combinations rather than requiring separate selection procedures for each trait.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If extensive breeding and selection processes are undertaken to develop new varieties, then desirable traits are achieved, but resources are consumed intensively

Engineering Contradiction:
Improvetrait selection precisionVSAvoidresource consumption
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent performs preliminary molecular marker analysis on breeding lines at early stages to identify those with the desired genetic potential. This preliminary screening allows resources to be concentrated on only those lines with the highest probability of success, rather than investing equal resources in all breeding lines throughout the entire development process.

Inventive Principle:
Principle #10Preliminary action
