Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars lack improved traits such as higher seed yield, disease resistance, drought tolerance, and altered fatty acid profiles, which are essential for enhancing agricultural productivity and nutritional value.
Innovation Solution
Development of a new soybean cultivar (20150718) with specific genetic modifications and breeding techniques to introduce desirable traits like disease resistance, improved fatty acid composition, and enhanced agronomic qualities, combined with methods for genetic analysis and transgenic modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the cultivar achieves improved seed yield, disease resistance, and agronomic quality, but the development process takes 6-12 years and requires significant resources
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental germplasm with specific desirable traits (disease resistance, yield potential, agronomic quality) before crossing. This advance preparation of parental materials with known characteristics accelerates the breeding process while ensuring the desired traits are present in the offspring, reducing the time required for multiple generations of selection and testing.
2Productivity
If multiple generations of crossing and selection are performed to achieve stable high-yielding cultivars, then the agronomic quality and yield are improved, but the resource consumption and time investment increase significantly
Solution Approach 1:
The patent replaces traditional mechanical breeding methods (repeated crossing, planting, and phenotypic selection over multiple generations) with molecular marker-assisted selection. By using DNA markers linked to desirable traits, breeders can identify and select plants with desired characteristics at the molecular level, significantly reducing the number of generations required and thereby reducing resource consumption while maintaining high yield improvement.
3Adaptability or versatility
If conventional breeding approaches are used to introduce transgenic or mutant traits, then the new traits are incorporated into the cultivar, but the process requires extensive backcrossing and time to recover the original cultivar background
Solution Approach 1:
The patent employs feedback mechanisms through molecular marker monitoring during the backcrossing process. By continuously tracking the genetic background using DNA markers, breeders can make informed decisions about which plants to advance, ensuring rapid recovery of the original cultivar background while simultaneously incorporating the desired transgenic or mutant traits. This feedback-driven approach simplifies the breeding program by providing objective criteria for selection at each generation.
