Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties that combine desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, with existing techniques being time-consuming and unpredictable, and lacking control over genetic combinations.

Innovation Solution

The development of the soybean variety A1026823, which is adapted for late group 3 growing regions, involves specific breeding techniques including backcrossing and genetic transformation to introduce desired traits like herbicide resistance, disease resistance, and improved nutritional quality, while maintaining the variety's morphological and physiological characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional soybean breeding methods are used, then existing varieties can be maintained, but the development of new varieties with multiple desirable traits is time-consuming and unpredictable

Engineering Contradiction:
Improvebreeding efficiencyVSAvoidbreeding cycle time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing genetic transformation and backcrossing operations in advance to introduce desired traits (disease resistance, drought tolerance, herbicide resistance) into the soybean variety before field testing and selection. This allows the breeding program to start with a head start on trait integration, reducing the overall breeding cycle time while maintaining predictability through controlled genetic modifications.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If conventional breeding techniques are used, then simple crossing is possible, but control over genetic combinations and trait stability is limited

Engineering Contradiction:
Improvetrait stabilityVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by systematically modifying genetic parameters through controlled backcrossing generations (BC1, BC2, BC3) and selecting specific phenotypic parameters (plant height, pod number, seed weight) to achieve stable trait combinations. This controlled modification of genetic and phenotypic parameters ensures trait stability while managing program complexity through structured selection criteria.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If multiple desirable traits are combined in a single variety, then agronomic performance improves, but the breeding process becomes more complex and less predictable

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

Solution Approach 1:

The patent applies merging by integrating multiple desirable traits (disease resistance, drought tolerance, herbicide resistance, improved grain quality) into a single soybean variety through systematic backcrossing. The breeding program combines these traits by crossing transformed lines with selected parents and maintaining multiple generations of backcrossing, thereby achieving high agronomic performance while managing complexity through a structured multi-trait integration approach.

Inventive Principle:
Principle #5Merging (Combining)
