Maize Inbred 1PTAE45 Accelerates Hybrid Development
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties is a time-consuming process that takes six to twelve years, and there is a continuous goal to create stable, high-yielding maize varieties with desirable traits such as disease resistance, drought tolerance, and improved agronomic characteristics.
Innovation Solution
A novel maize variety, 1PTAE45, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and drought tolerance, achieved through backcross conversion, genetic manipulation, and transformation, allowing for the production of hybrid seeds with enhanced agronomic traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding processes are used to develop new varieties with desirable traits, then the varieties achieve stable, high-yielding characteristics with disease resistance and drought tolerance, but the development process takes six to twelve years
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing inbred line 1PTAE45 with specific desirable traits (disease resistance, drought tolerance, yield potential) before hybrid development. This preliminary characterization of parent lines accelerates the breeding process by eliminating later selection steps while maintaining variety stability.
Solution Approach 2:
The patent uses copying by creating multiple hybrid combinations using inbred line 1PTAE45 as a parent. The stable genetic characteristics of 1PTAE45 are copied across different hybrid varieties, allowing rapid propagation of desirable traits without repeating the entire breeding process for each new variety.
2Adaptability or versatility
If multiple desirable traits are combined in a single maize variety through traditional breeding, then the variety achieves improved agronomic characteristics and yield, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent merges multiple desirable traits (disease resistance, drought tolerance, yield potential) into a single inbred line 1PTAE45 through prior breeding work. This consolidated parent line then transmits these combined traits to multiple hybrid varieties, simplifying the breeding process while maintaining trait versatility.
Solution Approach 2:
Inbred line 1PTAE45 serves as a universal parent with multi-functional desirable traits that can be combined with various other inbred lines to create different hybrid varieties. This universal parent line approach reduces breeding process complexity by using a single, versatile genetic resource rather than developing separate breeding programs for each trait combination.
