Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process, taking six to twelve years, and existing technologies face challenges in creating stable, high-yielding maize varieties with desirable traits such as disease resistance, drought tolerance, and improved agronomic characteristics.
Innovation Solution
The development of a novel maize variety, PH2DNS, through careful breeding and selection, incorporating traits like male sterility, disease resistance, and drought tolerance, achieved by backcross conversion, genetic manipulation, and transformation, allowing for the creation of hybrid seeds with enhanced agronomic properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding processes are used to develop new maize varieties, then stable and high-yielding varieties with desirable traits can be achieved, but the process takes six to twelve years which is time-consuming
Solution Approach 1:
The patent employs preliminary action by using molecular marker technology to identify and select desirable traits at early breeding stages. This allows breeders to predict and select for disease resistance, drought tolerance, and other agronomic characteristics before the variety is fully developed, significantly reducing the time required to achieve stable, high-yielding varieties while maintaining reliability through genetic screening.
2Adaptability or versatility
If traditional breeding methods are used, then maize varieties with multiple desirable traits can be developed, but the process requires extensive time and effort
Solution Approach 1:
The patent applies universality by developing a multi-functional breeding approach that combines traditional crossing methods with molecular marker-assisted selection. This integrated system simultaneously targets multiple desirable traits including disease resistance, insect resistance, drought tolerance, and yield improvement within a unified breeding program, increasing both the number of traits achieved and breeding efficiency.
Solution Approach 2:
The patent implements feedback mechanisms through molecular marker screening at various breeding stages. By continuously monitoring genetic markers associated with desirable traits and using this information to guide subsequent crossing and selection decisions, the breeding process becomes more efficient and targeted, allowing multiple traits to be accumulated systematically without excessive time investment.
3Adaptability or versatility
If conventional breeding processes are followed, then new maize varieties can be developed with improved agronomic characteristics, but the complexity and duration of the process increases
Solution Approach 1:
The patent replaces mechanical/time-consuming phenotypic evaluation methods with molecular marker-based genetic screening. Instead of waiting for plants to mature and expressing traits to assess agronomic characteristics, the system uses DNA markers to detect and select for desirable traits at the molecular level, simplifying the breeding process while maintaining or improving the quality of agronomic characteristics achieved.
