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 and achieving stability and uniformity in soybean breeding.

Innovation Solution

The soybean variety XB47F10 is developed through careful breeding and selection, combining desirable traits like disease resistance, drought tolerance, and improved agronomic characteristics, with methods including backcrossing and genetic marker profiles for introgressing new traits and ensuring phenotypic stability, allowing for the production of seeds with consistent performance.

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, but the process becomes time-consuming and resource-intensive

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

Solution Approach 1:

The patent employs molecular marker technology to provide real-time feedback on the genetic composition of breeding lines. By using DNA markers linked to desirable traits, breeders can immediately assess whether target genes are present and being inherited, eliminating the need for lengthy field testing to confirm trait presence. This feedback mechanism accelerates the breeding cycle while ensuring trait stability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical phenotypic selection methods with molecular genetic analysis. Instead of relying on visual observation and manual evaluation of plant traits in the field, the invention uses DNA-based marker systems to detect and track desirable genes at the molecular level, significantly reducing the time required for variety development while maintaining accuracy.

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

2Productivity

If multiple desirable traits are combined in a single variety, then agronomic performance is improved, but achieving uniformity and stability becomes difficult

Engineering Contradiction:
Improveseed yieldVSAvoidphenotypic uniformity
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent segments the complex task of combining multiple traits by using independent molecular markers for each desired trait. This allows breeders to track and select for each trait separately through marker-assisted selection, ensuring that all desirable genes are present and properly inherited. The segmentation approach maintains phenotypic uniformity by providing precise control over the genetic composition of the final variety.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If new traits are introduced through crossing, then variety improvement is achieved, but resource efficiency decreases

Engineering Contradiction:
Improvetrait diversityVSAvoidbreeding resource consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by pre-identifying and characterizing molecular markers associated with desirable traits before initiating breeding programs. This advance preparation allows breeders to efficiently screen and select parental lines that possess the desired genetic makeup, reducing the need for extensive crossing and field testing. The preliminary establishment of marker-trait associations streamlines the entire breeding process and conserves resources.

Inventive Principle:
Principle #10Preliminary action
