Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean cultivars face challenges in combining desirable traits such as higher seed yield, disease resistance, drought tolerance, and altered fatty acid profiles, which are time-consuming to develop and require precise planning and resource management.
Innovation Solution
Development of a new soybean cultivar 21040068 with genetically engineered traits for herbicide resistance, disease tolerance, and improved fatty acid composition, achieved through methods like backcrossing and genetic transformation, utilizing expression vectors and promoters to introduce specific genetic elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to combine desirable traits, then genetic diversity and trait integration are improved, but the breeding process becomes extremely time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-modifying parental germplasm through mutagenesis or transgenic transformation before crossing. This allows desirable traits to be introduced in advance into the parental lines, so that the F1 generation already possesses the desired characteristics without requiring multiple generations of selection and backcrossing. The preliminary genetic modification of parents eliminates the need for lengthy traditional breeding processes.
2Reliability
If multiple crossing and selection steps are performed to achieve stable high-yielding cultivars, then trait stability and productivity are improved, but the complexity and resource requirements of the breeding program increase
Solution Approach 1:
The patent applies the taking out principle by extracting and isolating specific desirable traits through molecular markers and selecting only the necessary parental combinations. Instead of performing comprehensive multi-generational crossing programs, the method extracts the key genetic factors responsible for desired traits and directly introduces them through targeted crosses or genetic transformation, thereby reducing program complexity while maintaining trait stability.
3Productivity
If conventional breeding approaches are used to improve seed yield and quality, then genetic improvement is achieved, but the process requires extensive land, time, and financial resources
Solution Approach 1:
The patent applies parameter changes by modifying the fundamental parameters of the breeding process itself. Instead of using conventional slow-paced crossing and selection, the method changes the time parameter through accelerated generation advancement techniques and the genetic parameter through mutagenesis or transgenic introduction of yield-related genes. This achieves rapid genetic improvement for seed yield without requiring extensive land and financial resources that conventional breeding demands.
