Solution Overview

Problem

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

Innovation Solution

The development of the soybean variety XBP39010, which is the result of careful breeding and selection, combining traits such as resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a process involving backcrossing and genetic marker-assisted breeding to ensure homozygosity and phenotypic stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional breeding methods are used to combine multiple desirable traits in soybean varieties, then the resulting variety may have improved disease resistance and yield, 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 employs molecular marker technology to provide continuous feedback on the genetic composition of breeding lines. By using DNA markers linked to desirable traits (such as disease resistance genes and fatty acid profile markers), breeders can screen and select plants carrying target traits at early generations, rather than waiting for phenotypic expression. This feedback mechanism accelerates the breeding process by enabling selection based on genotype rather than requiring multi-generation field testing for trait expression.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If multiple generations of breeding and selection are performed to achieve phenotypic stability and homozygosity, then the variety achieves uniformity and reliability, but the development timeline extends to 6-12 years

Engineering Contradiction:
Improvephenotypic stabilityVSAvoidbreeding efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent replaces the traditional mechanical/phenotypic selection system with a molecular/genetic selection system. Instead of relying on visual observation of phenotypic traits and multiple generations of field testing to achieve homozygosity, the invention uses DNA-based molecular markers to directly detect and track the inheritance of specific genes and genomic regions. This substitution allows breeders to identify homozygous lines and desirable trait combinations much earlier in the breeding process, dramatically reducing the time required to achieve phenotypic stability while maintaining breeding efficiency.

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

3Reliability

If extensive field testing and evaluation are conducted to ensure variety performance, then the variety achieves high reliability and agronomic soundness, but the resource consumption and complexity of the breeding program increase significantly

Engineering Contradiction:
Improveagronomic soundnessVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary genetic evaluation using molecular markers during early breeding generations, before advancing lines to extensive field testing. By performing preliminary selection based on DNA marker profiles that predict desirable traits (disease resistance, yield potential, fatty acid composition), the program pre-identifies the most promising breeding lines. This preliminary action filters out inferior lines early, reducing the number of candidates requiring resource-intensive multi-location field trials and complex evaluation programs, thereby maintaining reliability while reducing overall program complexity.

Inventive Principle:
Principle #10Preliminary action
