Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with improved traits such as disease resistance, herbicide tolerance, and nutritional quality, which are difficult to predict and require extensive research efforts due to the complexity of genetic combinations and environmental factors.
Innovation Solution
The development of the soybean variety 01067789, which includes specific genetic modifications and locus conversions for traits like herbicide resistance, disease resistance, and improved nutritional quality, achieved through genetic transformation and backcrossing techniques, allowing for the introduction of desired traits while maintaining the original variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity is increased, but the process becomes unpredictable and requires extensive research efforts
Solution Approach 1:
The patent applies parameter changes by modifying specific genetic loci through targeted conversion techniques. Instead of relying on conventional breeding that combines multiple genes through random recombination, the invention changes the parameters of specific loci to achieve predictable trait expression. This allows breeders to precisely control which traits are expressed and when, significantly reducing the unpredictability and time required for variety development.
Solution Approach 2:
The patent uses locus conversion as an intermediary mechanism between parental genomes. Rather than directly combining entire genomes through crossing and selection, the invention introduces a conversion process that selectively transfers specific loci from one parent to another. This intermediary step provides precise control over trait inheritance, making the breeding process more predictable and efficient.
2Adaptability or versatility
If multiple traits are combined in a single variety through conventional breeding, then trait diversity is improved, but the complexity of genetic combinations increases
Solution Approach 1:
The patent applies segmentation by breaking down the complex task of combining multiple traits into manageable loci-specific conversions. Instead of attempting to combine all desired traits simultaneously through multiple crosses and selections, the invention segments the breeding process into individual locus conversions that can be performed and tracked separately. This reduces the complexity of genetic combinations at any given stage while still achieving the ultimate goal of multi-trait varieties.
Solution Approach 2:
The patent applies local quality by allowing different regions of the genome (specific loci) to have different origins and functions. Each converted locus can be independently selected and optimized for its specific function, while the rest of the genome maintains its original characteristics. This localized approach to genetic modification simplifies the overall complexity by treating each trait locus independently rather than managing entire genome combinations.
3Reliability
If extensive crossing and selection is performed to achieve desired traits, then trait improvement is achieved, but the breeding process becomes inefficient
Solution Approach 1:
The patent applies preliminary action by performing locus conversion early in the breeding process to establish desired traits before subsequent selection and testing stages. By pre-converting specific loci with known functions and effects, the invention eliminates the need for extensive crossing and selection to discover and fix these traits. This preliminary establishment of desired traits significantly improves breeding efficiency while maintaining high accuracy in trait improvement.
