Soybean Variety D4256925 Breeding Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean varieties is a time-consuming and unpredictable process due to the complexity of combining desirable traits such as higher seed yield, disease resistance, and environmental adaptability, which requires extensive research and resource allocation without guaranteed results.
Innovation Solution
The soybean variety D4256925 is developed through specific breeding methods, including crossing and selection techniques, to produce plants with improved traits like herbicide resistance, disease resistance, and adaptability, which can be propagated and used in hybrid production to enhance soybean breeding programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to combine desirable traits, then genetic diversity and adaptability are improved, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with known desirable traits (herbicide resistance, disease resistance, yield characteristics) before crossing. This advance selection and characterization of parents reduces the time needed for later selection steps and makes the breeding process more predictable while maintaining genetic diversity and adaptability.
2Reliability
If extensive crossing and selection is performed to achieve desirable traits, then trait improvement is enhanced, but resource expenditure increases
Solution Approach 1:
The patent employs feedback mechanisms by systematically evaluating and selecting parental lines based on their performance for specific traits (herbicide resistance, disease resistance, yield) before crossing. This feedback-driven selection ensures that only lines with proven desirable traits are advanced, improving the reliability of trait inheritance while reducing unnecessary resource expenditure on ineffective breeding combinations.
3Adaptability or versatility
If multiple traits are combined in breeding programs, then overall variety improvement is enhanced, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct modules: selection of parents with specific traits (herbicide resistance, disease resistance), controlled crossing to combine traits, and systematic evaluation of progeny. This segmented approach allows multiple traits to be combined methodically, improving overall variety enhancement while managing program complexity through structured, stepwise procedures.
