Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with improved traits such as disease resistance, drought tolerance, and herbicide resistance, which are difficult to predict and require extensive research and time due to the complexity of genetic combinations and environmental factors.
Innovation Solution
The development of the soybean variety 01073340, which involves genetic modification through single locus conversion using transgenic genes for herbicide resistance, disease resistance, and other desirable traits, combined with advanced breeding techniques like backcrossing and genetic marker-assisted selection, to produce plants with specific desirable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity and trait combinations can be explored, but the process requires extensive research and time due to complexity of genetic combinations and environmental factors
Solution Approach 1:
The patent applies parameter changes by using molecular markers to directly detect and select for specific genetic traits, transforming the breeding process from phenotypic selection to genotypic selection. This allows breeders to predict and select for desired traits (such as disease resistance, yield components, and quality characteristics) at the DNA level, significantly reducing the time required for breeding while improving predictability of trait expression in the final variety
2Productivity
If multiple traits are combined in a single variety to achieve high yield and resistance, then the agronomic quality and productivity improve, but the breeding complexity and difficulty of selecting superior combinations increase
Solution Approach 1:
The patent applies segmentation by breaking down the complex breeding program into discrete, manageable components through the use of specific molecular markers for different traits. Each marker corresponds to a specific genetic locus or trait of interest, allowing breeders to independently track and select for multiple traits simultaneously. This segmentation of the breeding process into marker-specific selection steps reduces overall program complexity while enabling the combination of multiple desirable traits in a single variety
3Reliability
If extensive phenotypic evaluation and field testing are conducted to ensure variety stability and superiority, then the reliability and agronomic soundness of the variety improve, but the time and resources required for variety development increase
Solution Approach 1:
The patent applies preliminary action by performing molecular marker-based genetic evaluation early in the breeding process, before extensive field testing is required. By using markers to predict performance and select superior genotypes at the seedling or early vegetative stage, the program can eliminate inferior lines early, reducing the number of plants that need to undergo time-consuming and resource-intensive field trials while maintaining confidence in the stability and superiority of selected varieties
