Maize Inbred 1PBNH61 for Accelerated 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 a novel maize variety, 1PBNH61, which incorporates specific traits like male sterility, disease resistance, and drought tolerance through backcross conversion, genetic manipulation, and transformation, along with processes for crossing and producing hybrid seeds, ensuring a homogeneous population of inbred seeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding methods are used to combine desirable traits, then stable and agronomically sound maize varieties are developed, but the process takes six to twelve years which is time-consuming
Solution Approach 1:
The patent creates a preliminary inbred line (1PBNH61) with pre-integrated desirable traits including male sterility, disease resistance, and drought tolerance. This pre-prepared genetic foundation allows for accelerated hybrid development without sacrificing variety stability, reducing the overall breeding timeline from 6-12 years to a more efficient process.
Solution Approach 2:
The inbred line 1PBNH61 serves as an intermediary genetic platform that bridges traditional breeding and modern hybrid production. By incorporating male sterility and other desirable traits into this intermediate line, the patent enables more efficient subsequent crossing and hybrid development while maintaining the stability characteristics of traditional breeding.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then agronomic quality and yield are improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent merges multiple desirable traits including male sterility, disease resistance, drought tolerance, and high yield potential into a single inbred line (1PBNH61). This consolidation of traits into one parental line simplifies the overall breeding process by reducing the number of separate crossing and selection steps needed to achieve multi-trait hybrids.
Solution Approach 2:
The inbred line 1PBNH61 is designed as a universal parental line that can be crossed with multiple different inbreds to produce hybrids with consistent desirable traits. The line's male sterility and other integrated characteristics make it a multi-functional tool that simplifies hybrid production across different crossing combinations.
