Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new pepper cultivars is a time-consuming and unpredictable process due to the complexity of inheritance and the lack of control over genetic traits, requiring extensive research and resources to identify superior genetic combinations for desirable traits such as yield, disease resistance, and agronomic quality.
Innovation Solution
The introduction of hybrid pepper cultivar 'E 499526', which combines high yield potential, mild flavor, and resistance to certain diseases, along with methods for producing transgenic plants using genetic marker-enhanced selection and transformation, allowing for the incorporation of desirable traits like herbicide resistance and improved nutritional quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop new pepper cultivars, then desirable traits such as yield, disease resistance, and agronomic quality can be combined, but the process becomes time-consuming and unpredictable due to the complexity of inheritance
Solution Approach 1:
The patent employs marker-assisted selection where DNA markers provide feedback on the genetic composition of breeding plants. This allows breeders to track inheritance of desired traits through generations, making the breeding process more predictable and reducing the time required to develop new cultivars with specific trait combinations.
Solution Approach 2:
The patent replaces traditional phenotypic selection (visual inspection and manual selection) with molecular marker-based genotypic selection. This substitution of mechanical/visual methods with molecular biological methods enables more accurate and faster identification of plants carrying desired genetic traits, thereby reducing breeding time and improving reliability.
2Reliability
If extensive research and resources are invested in traditional breeding to identify superior genetic combinations, then desirable traits can be achieved, but the resource intensity and unpredictability increase
Solution Approach 1:
The patent replaces resource-intensive traditional phenotypic evaluation and extensive field testing with efficient molecular marker analysis. This substitution allows for early-stage identification of desired traits in the laboratory, reducing the need for extensive field trials and associated resources while improving the accuracy of trait identification.
Solution Approach 2:
The patent performs preliminary genetic analysis using DNA markers at early breeding stages, before plants are grown to maturity. This preliminary action allows for the early identification and selection of plants with desired genetic combinations, preventing waste of resources on plants that will not express the desired traits, thereby improving resource efficiency.
3Adaptability or versatility
If conventional breeding methods are used, then natural genetic variation is utilized, but control over specific genetic traits is limited and inheritance complexity increases
Solution Approach 1:
The patent uses DNA markers to provide feedback on the presence and inheritance of specific genetic traits. This feedback mechanism allows breeders to precisely track which traits are being inherited through generations, enabling better control over genetic composition and simplifying the management of inheritance complexity by providing clear information about genetic transmission.
