Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties that combine desirable traits such as disease resistance, drought tolerance, and improved agronomic qualities, 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 A1026828, which is adapted for late group 3 growing regions, involves a breeding history that includes specific crosses and selection methods to combine traits like disease resistance, herbicide resistance, and improved agronomic characteristics, and can be used in various breeding protocols, including backcrossing and genetic transformation to introduce desired traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to combine multiple desirable traits, then trait combination is achieved, but the breeding process becomes extremely complex and time-consuming
Solution Approach 1:
The patent applies parameter changes by modifying specific genetic loci in the soybean variety through targeted genetic transformation. Instead of attempting to combine multiple traits through complex conventional breeding, the invention transforms specific genes (such as the epsps gene for herbicide resistance) while maintaining the existing stable genetic background of the parent variety ABL3705N0R. This approach changes the genetic parameters directly rather than relying on multi-generational crossing and selection, thereby achieving trait combination without increasing breeding process complexity.
2Reliability
If extensive research efforts are invested to predict and select desirable traits, then trait stability is improved, but research time and resources increase significantly
Solution Approach 1:
The patent employs preliminary action by first establishing a stable, high-yielding parent variety (ABL3705N0R) with known desirable traits including disease resistance and agronomic quality. This pre-characterized parent serves as a reliable genetic foundation. When introducing new traits through transformation, the stable background is already in place, eliminating the need for extensive multi-generational testing to ensure trait stability. The preliminary development of the stable parent variety allows subsequent trait additions to be achieved more quickly with greater confidence in overall stability.
3Adaptability or versatility
If multiple parental germplasm are crossed to achieve desired trait combinations, then genetic diversity is improved, but the complexity of managing and tracking genetic combinations increases
Solution Approach 1:
The patent applies the extraction principle by isolating and transforming specific target genes (such as epsps for herbicide resistance) from donor sources and inserting them into the parent variety ABL3705N0R. This extracts only the necessary genetic elements needed for the desired trait without requiring complex crosses with multiple parental germplasm. The transformation process directly introduces the specific gene of interest while maintaining the integrity of the parent variety's existing genetic combination, thereby achieving genetic diversity enhancement without increasing the complexity of managing and tracking multiple parental contributions.
