Solution Overview

Problem

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

Innovation Solution

The development of the soybean variety XB006E15R, which has been bred to combine improved traits like resistance to aerial web blight, aphid antibiosis, and tolerance to abiotic stresses, through a comprehensive breeding program involving selection and introgression of desirable traits, allowing for efficient production and distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine multiple desirable traits, then the variety achieves improved disease resistance and stress tolerance, but the breeding process becomes extremely time-consuming and resource-intensive

Engineering Contradiction:
Improvedisease resistance and stress toleranceVSAvoidbreeding process duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The breeding program is divided into distinct phases: initial cross between RJS00901 and 900Y71, followed by systematic selection across multiple generations (F1-F4), and final variety development. This segmentation allows parallel tracking of different trait combinations and reduces overall development time while maintaining thorough trait evaluation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The parental varieties RJS00901 and 900Y71 were pre-selected for specific traits before crossing. RJS00901 contributed disease resistance and stress tolerance, while 900Y71 provided high yield potential. This preliminary selection of parents with complementary traits accelerates the breeding process by reducing the need for extensive trait combination work in later generations.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If multiple generations of selection and crossing are performed to achieve trait stability, then the variety achieves uniformity and stability, but the productivity of the breeding program decreases

Engineering Contradiction:
Improvetrait stability and uniformityVSAvoidbreeding program output
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The breeding program implements continuous feedback through multi-location and multi-year field trials. Each generation is evaluated for trait stability, and data from these trials inform subsequent selection decisions. This feedback mechanism ensures trait stability is achieved efficiently by identifying stable lines early, reducing the number of generations needed for final variety development.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Molecular marker technology is used to replace traditional phenotypic selection methods. Markers associated with desired traits (disease resistance, stress tolerance, yield) allow breeders to select plants with the correct genotype early in the breeding process, eliminating the need to grow plants to maturity for evaluation. This substitution dramatically accelerates the breeding cycle while maintaining trait stability.

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