Wheat Cultivar WB-700 Breeding for Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheat cultivars lack comprehensive resistance to multiple diseases and pests, as well as efficient methods for introducing desired traits such as herbicide tolerance and modified metabolism, which limits their agricultural productivity and adaptability.
Innovation Solution
The development of wheat cultivar WB-700, which involves crossing with plants possessing desired traits, followed by backcrossing to incorporate traits like herbicide resistance, disease resistance, and modified metabolism, while maintaining the physiological and morphological characteristics of WB-700, using genetic engineering and traditional breeding techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional breeding methods are used to introduce desired traits into wheat cultivars, then the breeding process is simple and maintains genetic stability, but the time required is lengthy and productivity is low
Solution Approach 1:
The patent applies preliminary action by pre-characterizing the WB-700 cultivar with multiple desirable traits (disease resistances, metabolic profiles, morphological characteristics) before using it as a parent in breeding programs. This preliminary preparation allows for more efficient trait introduction in subsequent crosses, reducing the overall breeding time while maintaining high productivity
2Productivity
If current wheat cultivars are used without comprehensive disease resistance, then the cultivars maintain their original genetic characteristics, but they suffer from reduced agricultural productivity due to lack of resistance to multiple diseases and pests
Solution Approach 1:
The patent merges multiple disease resistance traits (stripe rust, stem rust, leaf rust, powdery mildew, Septoria, Fusarium) along with modified metabolism traits and morphological characteristics into a single wheat cultivar WB-700. This combination of multiple beneficial traits in one cultivar simultaneously improves agricultural productivity while providing comprehensive protection against various diseases and pests
3Stability of the object's composition
If backcrossing is performed multiple times to incorporate desired traits, then the physiological and morphological characteristics of the original cultivar are maintained, but the breeding process complexity increases
Solution Approach 1:
The patent utilizes parameter changes by systematically varying the number of backcross generations (BC1, BC2, BC3, etc.) and selecting for specific trait combinations at each stage. This controlled progression through defined parameter changes allows maintenance of the original cultivar's essential characteristics while efficiently incorporating desired traits, managing breeding complexity through structured parameter variation
