Innovation Solution
The development of the soybean variety 01068466, 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
1Adaptability or versatility
If traditional breeding methods are used to develop new soybean varieties, then genetic diversity and trait combinations can be explored, but the process requires extensive time and research due to the complexity of genetic combinations and environmental factors
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (herbicide tolerance, disease resistance, yield characteristics) before crossing. The breeding program systematically evaluates parental germplasm and pre-determines crossing strategies based on target traits, reducing the time needed for random screening of genetic combinations in traditional breeding.
Solution Approach 2:
The patent changes breeding parameters by using marker-assisted selection to track specific genetic markers associated with desired traits through generations. This allows breeders to monitor and select for specific genetic parameters (marker presence/absence) rather than relying on phenotypic observation alone, accelerating the breeding process while maintaining genetic diversity.
2Reliability
If multiple traits are combined in a single variety through breeding, then improved agronomic quality and resistance are achieved, but the complexity of genetic combinations makes prediction of outcomes difficult
Solution Approach 1:
The patent applies feedback through marker-assisted selection, where DNA markers linked to desired traits are tracked through each generation of breeding. This provides continuous feedback on the genetic composition of breeding lines, allowing breeders to make informed decisions about which plants to advance or cross, thereby predicting and controlling trait outcomes despite genetic complexity.
Solution Approach 2:
The patent segments the complex task of combining multiple traits by focusing on one or a few key traits at a time through systematic crossing programs. Each breeding program targets specific trait combinations (e.g., herbicide tolerance plus disease resistance) rather than attempting to combine all possible traits simultaneously, making the genetic management more tractable and predictable.
3Productivity
If extensive research is conducted to ensure stable, high-yielding varieties, then agronomic soundness and yield are maximized, but the process requires significant time and resources
Solution Approach 1:
The patent applies preliminary action by conducting extensive field testing and evaluation of parental lines before crossing to ensure they possess the desired yield potential and agronomic characteristics. This pre-screening of parents based on proven performance reduces the need for extensive testing of numerous crossing combinations, accelerating the development of high-yielding varieties.
Solution Approach 2:
The patent changes the research approach by using molecular markers to predict trait inheritance and performance, replacing some traditional phenotypic screening with genotypic analysis. This parameter change from phenotype-based to genotype-based selection reduces the time and resources needed for field testing while maintaining confidence in yield and agronomic quality outcomes.
