Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean varieties lack improved combinations of traits such as higher seed yield, disease resistance, herbicide tolerance, and nutritional quality, which are essential for maximizing grain production and meeting agricultural demands.
Innovation Solution
Development of the soybean variety 01098202, which incorporates genetic modifications and locus conversions for traits like herbicide resistance, disease resistance, and improved nutritional quality, achieved through methods such as genome editing using engineered nucleases, and traditional breeding techniques like backcrossing and pedigree breeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding techniques are used to combine multiple traits, then the variety can achieve improved agronomic traits, but the breeding process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple desirable traits (herbicide tolerance, disease resistance, yield characteristics) into a single soybean variety through systematic breeding programs that integrate traditional crossing methods with modern selection techniques, achieving cumulative trait improvement in one unified variety
Solution Approach 2:
The breeding program performs preliminary selection and evaluation of parental lines for specific traits before crossing, and conducts preliminary field testing of hybrid combinations to identify promising varieties early in the development process, reducing overall program complexity
2Productivity
If multiple traits are combined in a single variety, then the agronomic performance is improved, but the breeding program requires more steps and resources
Solution Approach 1:
The breeding program implements continuous feedback loops through field testing, performance evaluation, and data analysis at multiple stages (F2, F3, F4 generations and beyond), allowing selective advancement of lines that meet predetermined yield and quality thresholds, thereby optimizing the time required to develop superior varieties
3Reliability
If selection criteria are stringent to ensure quality, then the variety performance is superior, but the number of viable candidates decreases
Solution Approach 1:
The breeding program segments the selection process into distinct stages with different criteria intensities - early generations (F2-F4) use moderate selection to maintain candidate diversity, while later generations (F5-F7 and multi-location testing) apply stringent selection criteria to finalize superior varieties, thus balancing quality requirements with maintaining an adequate candidate pool
