Maize Inbred PH47W4 Trait Stability and Development Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process, taking six to twelve years, and existing technologies face challenges in combining desirable traits such as disease resistance, drought tolerance, and high yield in a stable and agronomically sound manner.
Innovation Solution
The introduction of the novel maize variety PH47W4, which involves crossing with other maize plants to introduce traits like male sterility, disease resistance, and improved yield through backcross conversion, genetic manipulation, and transformation, along with the use of cytoplasmic or nuclear factors to confer specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding methods are used to combine desirable traits, then trait stability and agronomic soundness are improved, but the development time increases to six to twelve years
Solution Approach 1:
The patent applies preliminary action by pre-establishing stable inbred lines with desired traits (such as disease resistance, drought tolerance, and high yield) that can be readily combined in hybrid development. The inbred line PH47W4 was developed through systematic breeding to possess multiple desirable traits simultaneously, allowing breeders to skip lengthy selection phases and directly proceed to hybridization and testing, thereby reducing overall development time while maintaining trait stability.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then agronomic performance and yield stability are improved, but the breeding process complexity increases
Solution Approach 1:
The patent applies merging by combining multiple desirable traits (disease resistance, drought tolerance, high yield, and stress resistance) into a single integrated inbred line PH47W4. This consolidation allows breeders to work with one pre-developed genetic package rather than separately developing and combining multiple trait lines, thereby simplifying the breeding process while achieving superior agronomic performance and yield stability across diverse environments.
