Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean varieties lack improved combinations of traits such as higher seed yield, disease and insect resistance, drought and heat tolerance, better agronomic quality, and enhanced compositional traits, which are essential for maximizing grain production and meeting food demands.
Innovation Solution
Development of the novel soybean variety 01098358, which includes genetic modifications for herbicide resistance, disease resistance, and improved nutritional quality, achieved through genetic transformation using engineered nucleases and single locus conversions, along with breeding methods like backcrossing and hybridization to enhance desired traits.

Engineering Contradiction Analysis
1Productivity
If conventional breeding methods are used to develop soybean varieties, then genetic diversity can be maintained, but the development of stable high-yielding varieties with multiple improved traits takes excessive time and resources
Solution Approach 1:
The patent applies parameter changes by modifying specific genetic loci in the soybean genome through targeted mutation techniques. This allows breeders to change specific traits (such as disease resistance, yield components, or maturity) without altering the entire genome, thereby accelerating the breeding process while maintaining stability of other important traits.
Solution Approach 2:
The patent employs preliminary action through the use of molecular markers and genomic selection tools that allow breeders to identify and select desired genetic traits before phenotypic expression occurs. This enables early selection of superior genotypes, reducing the time required for multi-generation field testing and variety stabilization.
2Adaptability or versatility
If multiple traits are combined in a single variety through conventional breeding, then agronomic improvement is achieved, but the complexity of the breeding program increases significantly
Solution Approach 1:
The patent applies segmentation by breaking down the complex task of multi-trait improvement into separate, manageable genetic loci. Each desired trait is targeted at a specific genomic location, allowing breeders to accumulate multiple independent mutations or gene transfers in a systematic manner rather than attempting to combine all traits simultaneously through traditional crossbreeding.
Solution Approach 2:
The patent uses molecular markers and genomic tools as intermediaries to facilitate the combination of multiple traits. These markers serve as mediators that allow breeders to track and select for multiple desired loci simultaneously, simplifying the management of complex breeding programs by providing objective, DNA-based selection criteria.
3Reliability
If genetic modifications are introduced to confer herbicide resistance and disease resistance, then agronomic performance is improved, but the variety may face regulatory and consumer acceptance challenges
Solution Approach 1:
The patent employs CRISPR-Cas9 and other genome editing technologies that can create precise, targeted modifications without leaving behind foreign DNA sequences or complex transgenic constructs. This approach creates simpler, more transient genetic changes that are easier to regulate and may be more readily accepted by consumers compared to traditional transgenic methods, while still achieving the desired disease and herbicide resistance.
