Stable Wheat Variety Breeding for Yield and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheat varieties often lack a balanced combination of desirable traits such as high seed yield, disease resistance, drought tolerance, and improved milling properties, which are essential for enhancing agricultural productivity and food product quality.
Innovation Solution
Development of a new wheat variety, 6PNKF96B, which is homozygous and stable, and can be bred or genetically modified to incorporate traits like herbicide resistance, disease resistance, and altered nutritional content through methods such as cross-pollination, backcrossing, and genetic transformation using CRISPR/Cas system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wheat breeding methods are used to combine multiple desirable traits, then the complexity of the breeding process increases significantly, but the ability to achieve a balanced combination of yield, disease resistance, and milling properties remains limited
Solution Approach 1:
The patent applies parameter changes by utilizing molecular markers to track and select for multiple desirable traits simultaneously during breeding. This molecular marker-assisted selection approach transforms the traditional phenotype-based selection into a genotype-based selection system, enabling more efficient combination of traits such as disease resistance, yield, and milling properties without proportionally increasing breeding program complexity
2Stability of the object's composition
If extensive genetic modification and backcrossing are performed to achieve homozygosity and stability, then the purity and uniformity of the wheat variety improve, but the time and resources required for development increase
Solution Approach 1:
The patent employs preliminary action through molecular marker-assisted selection during the breeding process. By using molecular markers to identify and select for desired traits at early stages of breeding, the method enables more rapid achievement of homozygosity and variety stability compared to traditional phenotype-based selection methods, thereby reducing the overall development time while maintaining high uniformity standards
3Productivity
If existing wheat varieties are used without further breeding, then the current productivity level is maintained, but the ability to improve yield and nutritional quality is limited
Solution Approach 1:
The patent applies universality by developing wheat varieties that simultaneously express multiple desirable traits including high yield, disease resistance, drought tolerance, and improved nutritional quality. The molecular marker-assisted selection methodology enables the integration of these diverse traits into single varieties, creating multi-functional wheat that addresses multiple productivity and adaptability requirements concurrently rather than requiring separate breeding programs for each trait
