Maize Inbred PH2S9H Breeding Acceleration
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
A novel maize variety, PH2S9H, 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 creation of hybrid seeds with enhanced agronomic characteristics.
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 creates a preliminary inbred line PH2S9H with predetermined desirable traits (disease resistance, drought tolerance, male sterility) that can be rapidly combined with other inbreds to produce hybrids, eliminating the need for lengthy field testing and selection processes that traditionally take 6-12 years
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the variety has improved agronomic characteristics including disease resistance and drought tolerance, but the complexity of the breeding process increases
Solution Approach 1:
The patent merges multiple desirable traits (disease resistance, drought tolerance, male sterility) into a single inbred line PH2S9H through systematic breeding, allowing these traits to be inherited together in hybrid offspring without requiring separate breeding programs for each trait
Solution Approach 2:
The inbred line PH2S9H serves multiple functions: it provides disease resistance, drought tolerance, and male sterility simultaneously, and can be used as a parent in multiple hybrid combinations, making it a universal solution for improving maize varieties
3Productivity
If conventional hybrid seed production is used, then high yielding maize varieties are produced, but the time required from first cross to finished seed delivery is six to twelve years
Solution Approach 1:
The patent performs preliminary breeding actions to create inbred line PH2S9H with all desired traits incorporated before hybrid seed production, allowing rapid commercialization of high-yielding hybrids without the traditional 6-12 year development timeline
