Solution Overview

Problem

Soybean breeders face challenges in developing stable, high-yielding varieties that are resistant to diseases, insects, and abiotic stresses, with existing breeding processes being time-consuming and resource-intensive, and few commercial varieties meeting the desired trait combinations.

Innovation Solution

The development of the soybean variety RJS32001, which combines resistance to multiple diseases, including Phytophthora, SCN, Frogeye leaf spot, and herbicides, along with improved agronomic traits, achieved through careful selection and breeding, allowing for efficient production and distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional soybean breeding processes are used to develop new varieties, then desirable traits can be combined in a single variety, but the process takes 6-12 years and requires significant resources

Engineering Contradiction:
Improvecombination of desirable traitsVSAvoidbreeding process duration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing parental germplasm with specific desirable traits (disease resistance, yield potential, abiotic stress tolerance) before crossing. This upfront preparation of parental lines with known trait profiles accelerates the breeding process by eliminating later characterization steps and enabling more efficient selection of progeny that inherit the desired trait combinations.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If breeders select for multiple desirable traits including disease resistance and yield, then superior varieties are produced, but the selection process becomes increasingly complex and resource-intensive

Engineering Contradiction:
Improvevariety stability and performanceVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct functional modules: (1) selection of parental lines with specific trait profiles, (2) controlled crossing to combine traits, (3) evaluation of progeny for target traits, and (4) selection of superior varieties. This modular approach to breeding allows systematic management of multiple traits and reduces overall program complexity by organizing the selection process into manageable, sequential steps.

Inventive Principle:
Principle #1Segmentation

3Productivity

If breeders focus on maximizing grain production and supply, then food security is improved, but fewer varieties (less than 25 out of 500,000+) meet the desired trait combinations for commercial use

Engineering Contradiction:
Improvegrain production volumeVSAvoidtrait combination precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by establishing specific quantitative thresholds and performance targets for key traits (e.g., minimum yield potential, disease resistance ratings, stress tolerance levels). By defining precise parameter ranges for desirable traits and using these as selection criteria, the breeding program efficiently filters the 500,000+ potential varieties down to the less than 25 that meet all commercial requirements, balancing high grain production with precise trait combination.

Inventive Principle:
Principle #35Parameter changes
