Wheat Variety 6PSRG14 Marker-Assisted Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheat breeding methods face challenges in developing varieties that combine desirable traits such as high seed yield, disease resistance, drought tolerance, and improved agronomic characteristics in a single variety, while maintaining genetic stability and uniformity.
Innovation Solution
The development of the wheat variety 6PSRG14, which involves genetic modification and locus conversion techniques to introduce traits like herbicide resistance, disease resistance, and altered nutritional content, along with traditional breeding methods to ensure stability and uniformity, and the use of advanced plant breeding techniques like double haploidy and marker-assisted selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine multiple desirable traits, then the variety can achieve high seed yield, disease resistance, and drought tolerance, but the process involves numerous steps with significant intervention and takes considerable time
Solution Approach 1:
The patent employs marker-assisted selection to preliminarily identify and select plants carrying desired trait combinations before traditional breeding steps, accelerating the breeding process by predicting offspring traits based on molecular markers rather than waiting for phenotypic expression
Solution Approach 2:
The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based selection systems, using DNA markers to detect and select for desirable traits such as disease resistance and drought tolerance, thereby reducing the time required for breeding development
2Adaptability or versatility
If genetic modification and locus conversion techniques are applied to introduce desired traits, then the variety achieves improved agronomic characteristics and nutritional content, but the complexity of the breeding process increases
Solution Approach 1:
The patent uses molecular markers as intermediaries to bridge the gap between genetic modification/locus conversion and phenotypic expression, enabling selection of plants with desired traits through marker detection rather than complex phenotypic analysis
Solution Approach 2:
The patent changes the selection parameter from phenotypic observation to molecular marker detection, simplifying the breeding process by using DNA-based parameters that directly indicate presence of desired traits without requiring complex agronomic evaluations
3Productivity
If multiple parental germ plasm are crossed to combine desirable traits, then the variety achieves improved seed yield and stress tolerance, but maintaining genetic stability and uniformity becomes challenging
Solution Approach 1:
The patent implements feedback through marker-assisted selection at multiple breeding stages, continuously monitoring and selecting for plants that maintain both high yield potential and genetic uniformity by detecting marker profiles that indicate desired trait combinations
Solution Approach 2:
The patent replaces traditional phenotypic selection with molecular marker-based selection to maintain genetic uniformity, using DNA markers to ensure consistent inheritance of desirable traits across generations while preserving high yield potential
