Solution Overview

Problem

The development of new maize varieties is a time-consuming process that takes six to twelve years, and there is a continuous need for stable, high-yielding maize varieties with improved traits such as disease resistance, drought tolerance, and better agronomic characteristics.

Innovation Solution

A novel maize variety, PH48AR, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and improved agronomic characteristics, using techniques such as backcross conversion, genetic manipulation, and transformation, allowing for the creation of hybrid maize seeds and plants with specific desirable traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maize breeding methods are used, then stable high-yielding varieties with improved traits can be developed, but the process takes six to twelve years which is time-consuming

Engineering Contradiction:
Improvestability of maize varietyVSAvoidbreeding time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-characterizing the PH48AR inbred line with multiple desirable traits (disease resistance, drought tolerance, yield potential) before hybridization. This preliminary preparation allows breeders to immediately create superior hybrids without needing to spend 6-12 years developing the base inbred line, thus reducing overall breeding time while maintaining variety stability

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple desirable traits are combined in a single variety, then disease resistance, yield, and agronomic characteristics improve, but the breeding process becomes more complex

Engineering Contradiction:
Improvenumber of desirable traitsVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple desirable traits (disease resistance, drought tolerance, yield potential, early maturity) into a single PH48AR inbred line through systematic breeding. This consolidation allows breeders to combine this pre-packaged multi-trait inbred with other complementary inbreds to create superior hybrids, simplifying the overall breeding process while maintaining high adaptability and versatility

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A novel maize variety designated PH48AR and seed, plants and plant parts thereof are provided. Methods for producing a maize plant comprise crossing maize variety PH48AR with another maize plant are provided. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into PH48AR through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby are provided. Hybrid maize seed, plants or plant parts are produced by crossing the variety PH48AR or a locus conversion of PH48AR with another maize variety.
