Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved agronomic qualities, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to genetic variability and difficulty in replicating superior varieties.
Innovation Solution
The development of the soybean variety A1026436, which is adapted for late group 4 growing regions, involves a specific breeding history and includes methods for crossing with itself or other plants to produce hybrid seeds and plants, utilizing techniques like backcrossing and genetic transformation to introduce desired traits like herbicide resistance and disease resistance, while maintaining the variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties with desirable traits, then genetic variability and unpredictability increase, but the breeding process becomes time-consuming and difficult to replicate
Solution Approach 1:
The patent applies preliminary action by pre-establishing a standardized breeding protocol that includes specific parental line selections (A1026436 as recurrent parent), controlled crossing procedures, and defined selection criteria. This predetermined framework allows for consistent replication across different breeding cycles and locations, reducing the time required for each cycle while maintaining reliability through repeatable results.
Solution Approach 2:
The patent utilizes parameter changes by systematically varying specific breeding parameters such as the choice of parental lines, crossing ratios, and selection intensities. By optimizing these parameters based on performance data from previous cycles, the breeding program achieves both faster cycle times and consistent production of superior varieties with desirable traits like disease resistance and high yield.
2Adaptability or versatility
If conventional breeding techniques are used to combine desirable traits from parental germplasm, then trait combination capability improves, but the process becomes unpredictable and difficult to control
Solution Approach 1:
The patent implements feedback mechanisms by continuously monitoring and evaluating the performance of breeding lines and varieties in controlled trials. Performance data from multiple environments and years are fed back into the breeding program to refine selection criteria and parental line choices. This feedback loop enables predictable combination of desirable traits while maintaining adaptability to different genetic backgrounds and environmental conditions.
Solution Approach 2:
The patent applies segmentation by dividing the breeding program into distinct, manageable phases: parental line selection, controlled crossing, F1 generation evaluation, F2 generation selection, and variety release. Each phase has specific objectives and criteria, allowing for systematic combination of traits while maintaining control over the breeding process. The segmentation enables reproducible results by standardizing each phase's protocols.
3Productivity
If conventional breeding techniques are used to develop high-yielding varieties, then yield potential improves, but the varieties become less stable across different environments
Solution Approach 1:
The patent applies universality by developing breeding lines and varieties that are designed to perform well across multiple environments and genetic backgrounds. The recurrent parent A1026436 and its progeny are selected for general adaptability while maintaining high yield potential. This multi-functional approach allows the same breeding material to be effectively used in different locations and years, achieving both high productivity and environmental stability.
Solution Approach 2:
The patent utilizes dynamics by creating a flexible breeding program that can adapt to changing environmental conditions while maintaining core breeding objectives. The program dynamically adjusts selection criteria and parental line combinations based on observed performance in different environments. This dynamic approach enables the development of stable, high-yielding varieties that can maintain their performance across varying environmental conditions through continuous optimization.
