Solution Overview

Problem

The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as higher seed yield, disease resistance, drought tolerance, and improved agronomic characteristics, while existing methods face challenges in efficiently integrating these traits into stable, high-yielding varieties.

Innovation Solution

The introduction of the soybean variety XB36L14, which is the result of careful breeding and selection, combining traits like disease resistance, drought tolerance, and improved agronomic characteristics, and methods for producing and characterizing this variety, including genetic marker profiles and introgression of new traits through backcrossing and transformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine multiple desirable traits, then disease resistance and drought tolerance can be achieved, but the breeding process becomes extremely time-consuming and resource-intensive

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding process duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the breeding process by using molecular markers to identify and select specific trait combinations early in the breeding program. This allows breeders to work with segmented populations that already possess desired traits, rather than combining multiple traits through successive generations of crossing and selection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary action by using molecular marker screening to pre-identify plants carrying desired trait combinations before actual phenotypic selection. This preliminary genetic screening allows breeders to focus resources on promising candidates, significantly reducing the time required to develop varieties with multiple desirable traits.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If multiple traits are integrated through conventional breeding, then agronomic improvement is achieved, but resource efficiency decreases due to the complexity and duration of the process

Engineering Contradiction:
Improveseed yieldVSAvoidbreeding resource consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent implements feedback mechanisms through molecular marker-assisted selection, where genetic information is continuously monitored and used to guide breeding decisions. This feedback loop allows breeders to make informed selections based on genetic potential rather than waiting for phenotypic expression, optimizing resource allocation and reducing breeding program duration.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical phenotypic selection methods with molecular marker-based genetic screening. This substitution eliminates the need for lengthy field trials and environmental assessments, directly identifying plants with desired traits through DNA analysis, thereby conserving significant breeding resources.

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

3Productivity

If stable high-yielding varieties are developed through extensive breeding, then grain production is maximized, but the process requires complex planning and frequent changes in direction

Engineering Contradiction:
Improvegrain productionVSAvoidbreeding program complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent changes the fundamental parameter of trait selection from phenotypic observation to genotypic identification. By using molecular markers to detect specific DNA sequences associated with desirable traits, the breeding program can directly select for target parameters without being constrained by environmental variability or complex phenotypic expression patterns.

Inventive Principle:
Principle #35Parameter changes
