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 XBP40010, 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 cross-pollination, backcrossing, and genetic marker-assisted breeding to ensure uniformity and 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 variety achieves improved disease resistance, drought tolerance, and fatty acid profiles, but the breeding process becomes 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-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 desirable traits (disease resistance, drought tolerance, fatty acid profiles) through generations, making informed selection decisions early in the breeding process rather than waiting for phenotypic expression, thereby significantly reducing the time required to develop stable varieties with multiple desirable traits

Inventive Principle:
Principle #23Feedback

2Productivity

If extensive cross-breeding and selection are performed to achieve high yield and stability, then the variety performance is improved, but the complexity of the breeding program increases

Engineering Contradiction:
Improveseed yieldVSAvoidbreeding program complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent uses molecular markers as intermediaries to simplify the breeding program. Instead of performing extensive phenotypic evaluations and multiple generations of cross-breeding to achieve high yield and stability, breeders can use molecular markers linked to yield-related genes and stability traits to directly identify and select superior genotypes. This intermediary approach reduces the number of breeding cycles and simplifies program management while maintaining high productivity outcomes

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If multiple generations of breeding are conducted to ensure uniformity and stability, then the variety achieves consistent performance, but the resource requirements increase

Engineering Contradiction:
Improvevariety uniformityVSAvoidresource requirements
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The patent replaces the traditional mechanical/phenotypic selection system with a molecular-level selection system. Instead of growing multiple generations and evaluating physical traits to ensure uniformity and stability, breeders can use molecular markers to directly identify lines with the desired genetic composition. This substitution allows for early-generation selection, reducing the number of generations required and thereby decreasing resource requirements for land, water, and inputs while achieving the same level of variety uniformity and stability

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