Find Innovative SolutionsGenerate Solutions
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 nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, and often result in varied genetic combinations that are difficult to replicate.
Innovation Solution
The development of the soybean variety A1036361, which combines improved traits through specific breeding techniques such as backcrossing and genetic transformation, allowing for the introduction of desired loci while retaining the morphological and physiological characteristics of the original variety, and the use of tissue culture methods for regeneration and transformation.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding techniques are used to develop soybean varieties, then genetic diversity is increased, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (disease resistance, yield potential, nutritional quality) before initiating the breeding program. This preliminary selection of genetically superior parents accelerates the breeding process by ensuring that only promising genetic combinations are pursued, reducing the time required to develop stable high-yielding varieties.
Solution Approach 2:
The patent employs molecular markers to copy and track specific desirable genes through generations during backcrossing. This molecular copying mechanism allows breeders to precisely monitor the inheritance of target traits, making the breeding process more predictable and reducing the time needed to achieve stable genetic combinations compared to traditional phenotypic selection alone.
2Adaptability or versatility
If conventional breeding techniques are used to develop soybean varieties, then natural genetic combinations are achieved, but the results are unpredictable and difficult to replicate
Solution Approach 1:
The patent implements feedback through molecular marker-assisted selection, where DNA markers provide continuous information about the presence and inheritance of desirable genes throughout the breeding process. This feedback mechanism allows breeders to make informed decisions at each generation, ensuring consistent replication of target genetic combinations and improving the reliability of breeding results.
Solution Approach 2:
The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based genetic analysis. This substitution enables precise tracking and selection of specific genes, transforming the breeding process from an unpredictable art to a more controlled and replicable science, thereby improving result consistency.
3Manufacturing precision
If backcrossing and genetic transformation are used to introduce desired loci, then specific traits are improved, but the complexity of breeding protocols increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding protocol into distinct modular stages: initial cross, multiple backcross generations with marker selection, and final variety development. Each stage has specific molecular marker-based selection criteria, allowing complex trait introduction to be managed through systematic segmentation of the breeding process into manageable steps.
