Maize Inbred Line 1PSUB88 for Faster Stable Trait Introgression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties is a time-consuming process that requires years to combine desirable traits such as disease resistance, drought tolerance, and high yield, posing challenges in efficiently producing stable and agronomically sound maize varieties.
Innovation Solution
The development of the novel maize variety 1PSUB88, which incorporates genetic modifications and cytoplasmic factors for traits like male sterility, disease resistance, and improved agronomic characteristics through backcross conversion, genetic manipulation, and transformation, along with processes for crossing and hybrid seed production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding methods are used to combine desirable traits, then the resulting varieties have stable and agronomically sound characteristics, but the development process takes six to twelve years which is excessively time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing inbred line 1PSUB88 with specific desirable traits (disease resistance, drought tolerance, yield potential) before hybrid development. This advance preparation and pre-characterization of parental lines streamlines the breeding process, reducing the overall development time while maintaining variety stability through systematic trait selection and validation prior to crossing programs
2Productivity
If multiple desirable traits are combined in a single maize variety through breeding, then the variety achieves high yield and agronomic soundness, but the process requires numerous steps taking six to twelve years which reduces productivity
Solution Approach 1:
The patent implements preliminary action by pre-developing and characterizing inbred line 1PSUB88 with multiple desirable traits (disease resistance, drought tolerance, yield potential) before initiating hybrid development. This advance preparation consolidates multiple breeding steps into a more efficient process, reducing the six to twelve year timeline while maintaining high yield and agronomic productivity through systematic pre-selection and trait validation
3Adaptability or versatility
If traditional breeding processes are used to develop new maize varieties, then the varieties achieve maximal yield over different conditions and environments, but the extensive time required from first cross to seed delivery reduces the rate of variety improvement
Solution Approach 1:
The patent applies preliminary action by pre-characterizing inbred line 1PSUB88 for adaptability and yield stability across different environmental conditions before hybrid development. This advance environmental stress testing and performance validation under various conditions allows for faster variety release while maintaining maximal yield and agronomic soundness across diverse growing environments, reducing the six to twelve year development timeline
