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 are limited in efficiently introducing new traits into existing varieties.

Innovation Solution

The soybean variety XB48P13 is developed through careful breeding and selection, combining traits like disease resistance, drought tolerance, and improved agronomic characteristics, and methods for introgressing new traits such as transgenic or mutant traits into XB48P13 using backcrossing and genetic marker-assisted breeding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional breeding methods are used to develop new soybean varieties, then desirable traits can be combined in a single variety, but the process takes six to twelve years and requires significant resources

Engineering Contradiction:

Improvecombination of desirable traitsVSAvoidbreeding cycle duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent employs molecular marker-assisted selection that provides continuous feedback on the genetic composition of breeding lines. By monitoring specific DNA markers associated with desirable traits, breeders can track progress in real-time and make informed decisions about which lines to advance, significantly reducing the time required to develop new varieties while ensuring reliable combination of desired traits.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces traditional phenotypic selection methods with molecular marker-based genotypic selection. Instead of waiting for plants to mature and express traits physically, the system uses DNA markers to detect and select for desired genetic characteristics early in the breeding process, accelerating variety development from 6-12 years to a much shorter timeframe.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If traditional breeding methods are used, then new varieties can be developed, but resource efficiency is low due to the lengthy development process

Engineering Contradiction:

Improvevariety development successVSAvoidresource consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements preliminary action by using molecular markers to identify and select promising genetic combinations early in the breeding process, before significant resource investment is required for field trials and variety multiplication. This preliminary genetic screening allows breeders to focus resources only on the most promising lines, dramatically improving resource efficiency while maintaining high success rates.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent changes the selection parameter from phenotypic expression to genotypic marker detection. By measuring DNA markers rather than waiting for physical trait expression, the system accelerates the breeding process and reduces the time and resources required for variety development, while maintaining reliable selection for desirable traits.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If existing breeding methods are used, then soybean varieties with improved traits can be produced, but the process lacks precision in tracking and selecting specific genetic traits

Engineering Contradiction:

Improvetrait inheritanceVSAvoidtrait selection accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

Inventive Principle:

Principle #23Feedback

4Reliability

If conventional breeding approaches are used, then soybean varieties can be developed with desirable characteristics, but adaptability to introduce new traits is limited

Engineering Contradiction:

Improvevariety stabilityVSAvoidtrait introduction flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a universal molecular marker system that can detect and select for multiple different types of traits simultaneously. The same marker-assisted selection framework can be applied whether introducing disease resistance, yield improvement, or quality traits, making the breeding program highly adaptable and versatile while maintaining the stability and reliability of the base variety.

Inventive Principle:

Principle #6Universality (Multi-functionality)
