Maize Inbred 1PLUB62 for Stable Multi-Trait Breeding
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 1PLUB62, which incorporates specific traits like male sterility, disease resistance, and drought tolerance through backcross conversion, genetic manipulation, and transformation, along with the introduction of heritable traits and cytoplasmically-inherited characteristics, to enhance genetic diversity and stability.
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 time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing inbred line 1PLUB62 with specific desirable traits (disease resistance, drought tolerance, yield potential) before hybrid development. This preliminary characterization and selection of parental lines with complementary traits accelerates the breeding process by reducing the need for extensive multi-year field testing and selection cycles that would otherwise be required to identify suitable parent combinations.
2Adaptability or versatility
If multiple desirable traits are combined in a single maize variety, then the variety achieves maximal yield and agronomic performance, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies segmentation by dividing the complex task of combining multiple traits into manageable segments through the development of specialized inbred lines, each optimized for specific trait combinations. Inbred line 1PLUB62 represents a segmented solution that consolidates particular traits (disease resistance, drought tolerance, yield) into a single parental line, simplifying subsequent hybrid development while maintaining the complexity of multi-trait performance.
Solution Approach 2:
The patent applies universality by developing inbred line 1PLUB62 as a multi-functional parental line that can contribute multiple desirable traits (disease resistance, drought tolerance, yield potential) to various hybrid combinations. This universal inbred line serves multiple breeding objectives simultaneously, reducing the need for separate breeding programs for each trait combination and simplifying the overall breeding infrastructure.
