Solution Overview

Problem

There is a need for new hybrid peppers that are appealing to consumers and agronomically sound, with improved traits such as disease resistance, nutritional quality, and agronomic characteristics.

Innovation Solution

Development of hybrid pepper varieties 'E20S0463', 'E20S0465', and 'E20S0492' with specific resistance to various diseases, including Tobacco mosaic virus and root-knot nematodes, and enhanced nutritional qualities, achieved through controlled breeding and genetic selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional pepper varieties are used for commercial cultivation, then they have established agronomic characteristics, but they lack disease resistance and nutritional quality improvements

Engineering Contradiction:

Improvedisease resistanceVSAvoidproduction level

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies parameter changes by developing hybrid pepper varieties with modified genetic parameters that confer disease resistance while maintaining or improving productivity. The hybrid varieties 'E20S0463', 'E20S0465', and 'E20S0492' exhibit altered resistance parameters against specific diseases compared to parental lines, achieving both reliability improvement and productivity maintenance through controlled breeding programs that select for optimal parameter combinations

Inventive Principle:

Principle #35Parameter changes

2Reliability

If new hybrid varieties are developed through controlled breeding, then disease resistance and nutritional quality are improved, but breeding time and complexity increase

Engineering Contradiction:

Improvedisease resistanceVSAvoidbreeding time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent employs preliminary action by pre-selecting parental lines with specific desirable traits before initiating the hybridization program. The parental lines were carefully chosen and characterized in advance for disease resistance genes and agronomic performance, allowing the breeding process to proceed more efficiently. This preliminary characterization of parent stocks reduces the time required for subsequent hybrid evaluation and selection phases

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If hybrid pepper varieties are developed with enhanced traits, then consumer appeal and agronomic soundness are improved, but the complexity of breeding programs increases

Engineering Contradiction:

Improveagronomic soundnessVSAvoidbreeding program complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by developing hybrid varieties that simultaneously express multiple desirable traits including disease resistance, nutritional quality enhancement, and agronomic performance. The breeding program was designed to select for universal adaptability across different growing conditions while incorporating multiple trait improvements in single varieties, reducing the need for separate breeding programs for different traits

Inventive Principle:

Principle #6Universality (Multi-functionality)
