Solution Overview

Problem

Current wheat breeding methods face challenges in combining desirable traits such as high seed yield, disease resistance, drought tolerance, and improved agronomic characteristics into a single wheat variety, while maintaining uniformity and stability.

Innovation Solution

The development of the wheat variety A060130D1, which involves genetic modification and locus conversion through transgenic techniques, including the introduction of specific genes for traits like herbicide resistance, disease resistance, and abiotic stress tolerance, along with traditional breeding methods like backcrossing and selection, to create a stable and uniform germplasm.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to combine multiple desirable traits, then the complexity of the breeding process increases, but the uniformity and stability of the resulting variety may be compromised

Engineering Contradiction:
Improvecombination of desirable traitsVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The breeding process is segmented into distinct stages: initial cross-breeding to introduce diversity, followed by systematic selection and backcrossing to stabilize traits. This segmentation allows complex trait combination to be managed through controlled, sequential steps rather than simultaneous complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Preliminary selection of parental lines with complementary desirable traits is performed before the actual breeding process. This preliminary action ensures that the subsequent breeding steps work with pre-optimized genetic material, reducing the complexity of achieving uniformity and stability in the final variety.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If extensive genetic modification and backcrossing are performed to achieve trait combination, then the desirable traits are successfully integrated, but the time required for variety development increases

Engineering Contradiction:
Improvetrait integrationVSAvoidvariety development time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The breeding program maintains continuous useful action through overlapping generations and parallel breeding lines. Multiple backcrossing generations are conducted simultaneously with selection processes, ensuring that trait integration and stabilization occur in a continuous workflow rather than sequential steps, thereby reducing total development time.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The program employs partial backcrossing strategies where not all progeny undergo complete backcrossing cycles. Instead, selected individuals with desirable trait combinations are advanced more quickly, while others continue backcrossing. This partial action approach maintains progress in trait integration without the time cost of uniform exhaustive backcrossing of all lines.

Inventive Principle:
Principle #16Partial or excessive action

3Stability of the object's composition

If multiple selection criteria are applied to ensure trait stability, then the uniformity of the variety improves, but the difficulty of detecting and measuring traits increases

Engineering Contradiction:
Improvevariety uniformityVSAvoidtrait evaluation complexity
Core Design Contradiction:
Stability of the object's compositionVSDifficulty of detecting and measuring

Solution Approach 1:

Different selection criteria are applied to different traits and different stages of breeding. Morphological traits are evaluated in field conditions, while biochemical and molecular traits are assessed using specialized laboratory techniques. This localized application of quality standards allows comprehensive uniformity assessment without requiring all traits to be measured with equal complexity at all stages.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Traditional mechanical and visual trait assessment is supplemented and replaced with molecular marker technology and DNA-based selection methods. This substitution enables more accurate and efficient detection of genetic traits, reducing the difficulty of measuring complex characteristics while improving the precision of uniformity evaluation.

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