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 not efficiently combined in a single variety.
Innovation Solution
The development of the soybean variety 01072332, which incorporates specific genetic modifications and locus conversions, including transgenic genes for herbicide resistance and disease resistance, achieved through genetic transformation and backcrossing, allowing for the combination of desirable traits like glyphosate and dicamba tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional soybean breeding methods are used to develop varieties with multiple improved traits, then the breeding process becomes increasingly complex and time-consuming, but the ability to combine multiple desirable traits (disease resistance, drought tolerance, herbicide resistance) in a single variety is limited
Solution Approach 1:
The patent combines multiple desirable traits (glyphosate resistance, dicamba resistance, disease resistance, drought tolerance) into a single soybean variety through genetic transformation and backcrossing, merging functions that would traditionally require separate breeding programs into one unified variety
Solution Approach 2:
The patent uses molecular markers as intermediaries to track and select for multiple traits simultaneously during breeding, and employs transgenic events as mediators to introduce multiple resistance traits through controlled genetic transformation rather than traditional lengthy crossing programs
2Adaptability or versatility
If multiple backcrossing generations are performed to combine traits from different parental lines, then trait combination improves, but the time required for variety development increases significantly
Solution Approach 1:
The patent performs preliminary genetic transformation to introduce multiple resistance traits into a single genomic background before beginning the backcrossing program, rather than introducing traits during the lengthy backcrossing process, thereby reducing the overall development time
Solution Approach 2:
The patent uses molecular marker-assisted selection to provide feedback on the presence and combination of multiple traits during each backcrossing generation, allowing breeders to make informed selection decisions that efficiently combine desired traits while monitoring genetic recovery of the recurrent parent
3Productivity
If traditional breeding methods are used to achieve high yield stability, then yield potential can be improved, but resistance to multiple herbicides and diseases cannot be efficiently incorporated
Solution Approach 1:
The patent changes the genetic parameters of the soybean variety by introducing transgenic events that confer multiple herbicide resistances (glyphosate, dicamba) and disease resistances, thereby altering the variety's response to environmental stressors and improving both yield stability and resistance profile simultaneously
