Solution Overview

Problem

Soybean breeders face challenges in developing stable, high-yielding varieties with improved traits such as disease resistance, drought tolerance, and better agronomic qualities, as the process is time-consuming and resource-intensive, with only a small percentage of new varieties being selected for commercial use.

Innovation Solution

The development of the soybean variety XB47R07, which exhibits a valuable combination of traits including resistance to SCN race 3, sudden death syndrome, charcoal rot/drought complex, and glyphosate resistance, adapted for specific regions, allowing for improved yield potential and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to develop new varieties with improved traits, then disease resistance and yield potential are improved, 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 applies preliminary action by pre-screening parental lines for specific disease resistance traits (SCN race 3 resistance, sudden death syndrome resistance, charcoal rot resistance) and agronomic qualities before crossing. This preliminary selection and characterization of parental germplasm allows the breeding program to start with predetermined resistant parents, reducing the time required for disease resistance development in later generations.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If multiple desirable traits are combined in a single variety, then agronomic performance and yield are improved, but the complexity of the breeding program increases

Engineering Contradiction:
Improveyield potentialVSAvoidbreeding program complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct modular components: selecting parents with specific resistance traits (SCN race 3, sudden death syndrome, charcoal rot), evaluating them for agronomic qualities (maturity group, plant height, pod color, seed color), and systematically crossing them. This segmented approach to trait accumulation makes the complex multi-trait breeding program more manageable and systematic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies universality by developing a multi-purpose breeding framework that simultaneously addresses multiple disease resistances (SCN, sudden death syndrome, charcoal rot) and agronomic traits (yield, maturity, plant architecture) through a unified crossing and evaluation program. The parental lines are selected and evaluated for multiple traits concurrently, allowing the breeding program to achieve multiple objectives through integrated selection rather than separate breeding programs for each trait.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If extensive screening and evaluation of potential varieties is conducted, then selection precision for commercial use is improved, but resource consumption increases

Engineering Contradiction:
Improvevariety selection accuracyVSAvoidresource consumption
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent applies preliminary action by conducting advance evaluation of parental lines for disease resistance traits and agronomic qualities before the crossing program begins. Parents are pre-screened for SCN race 3 resistance, sudden death syndrome resistance, charcoal rot resistance, and agronomic characteristics (maturity group, plant height, pod color, seed color). This preliminary characterization reduces the need for extensive screening of progeny, as the resistant traits are already established in the parental generation.

Inventive Principle:
Principle #10Preliminary action
