Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soybean breeding is challenging due to the plant's self-pollinating nature, requiring extensive intervention by breeders to introduce desired traits, and the genetic complexity leads to unpredictable development of new cultivars, necessitating intensive research and long breeding processes.
Innovation Solution
The development of soybean cultivar CL1463369, which incorporates transgenes for herbicide resistance, disease resistance, insect resistance, and altered oil profiles, allowing for the introduction of desired traits through crossing and selection methods, including marker-assisted breeding and transformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual manipulation of sexual organs or male sterility systems is used to achieve hybrid crosses, then desired traits can be introduced, but the breeding process becomes highly unpredictable and requires intensive research and development
Solution Approach 1:
The patent replaces manual mechanical manipulation of sexual organs with molecular marker-based identification systems. Breeders use DNA markers to identify plants carrying desired alleles, substituting the complex mechanical process of manual cross-pollination and visual hybrid identification with a molecular detection system that tracks specific genetic sequences through generations.
Solution Approach 2:
The patent introduces molecular markers as intermediary elements that mediate between the breeder's intent and the actual trait expression. These markers serve as detectable proxies for desired traits, allowing breeders to track and select for specific alleles without directly observing the complex phenotypic outcomes of cross-pollination events.
2Productivity
If recurrent selection and mass selection methods are employed to improve populations, then yield and resistance traits can be enhanced, but the genetic complexity leads to unpredictable outcomes requiring multiple generations of selection
Solution Approach 1:
The patent performs preliminary identification of desired alleles using molecular markers before conducting selection and crossing operations. By detecting the presence of target alleles early in the breeding process, breeders can make informed decisions about which plants to cross or select, eliminating the need for multiple generations of phenotypic selection and accelerating the breeding timeline.
Solution Approach 2:
The patent implements a feedback mechanism where molecular marker analysis provides real-time information about the genetic composition of breeding populations. This feedback allows breeders to adjust selection strategies, cross designs, and population management decisions based on actual allele frequencies and combinations, rather than relying on slow phenotypic observation across multiple generations.
3Reliability
If the same starting parental material is used, then breeding can be replicated, but the vast genetic diversity ensures that the same two cultivars cannot be produced twice
Solution Approach 1:
The patent creates a molecular blueprint or copy of the desired genetic composition using marker profiles. By establishing a reference profile of marker alleles that define the target cultivar, breeders can reproduce the same genetic composition across different breeding attempts, even though the physical plants and their surrounding genetic diversity remain unique each time.
