Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tomato varieties lack sufficient resistance to Tomato Brown Rugose Fruit Virus (ToBRFV), Meloidogyne arenaria (Ma), Meloidogyne incognita (Mi), Meloidogyne javanica (Mj), Fusarium oxysporum f. sp. lycopersici (Fol) race EU0/1US, and Tomato Mosaic Virus (ToMV) strains 0, 1, 2, which affect yield and fruit quality.

Innovation Solution

Development of a hybrid tomato variety 72-MP0038 RZ with genetic resistance to ToBRFV, intermediate resistance to Ma, Mi, and Mj, resistance to Fol race EU0/1US, and resistance to ToMV strains 0, 1, 2, achieved through selective breeding and genetic enhancement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional tomato varieties are used, then cultivation is simpler, but resistance to multiple pathogens (ToBRFV, Ma, Mi, Mj, Fol, ToMV) is insufficient

Engineering Contradiction:

Improvedisease resistanceVSAvoidbreeding complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple disease resistance traits (ToBRFV, Ma, Mi, Mj, Fol, ToMV) into a single hybrid tomato variety by merging parental lines with complementary resistance profiles. This consolidation allows one variety to resist multiple pathogens simultaneously, resolving the contradiction between improving reliability and managing breeding complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hybrid tomato variety functions as a composite genetic material, integrating resistance genes from different parental sources. This composite genetic structure provides multi-pathogen resistance (ToBRFV, nematodes, Fusarium, mosaic virus) in a single variety, achieving high reliability without requiring multiple separate varieties.

Inventive Principle:

Principle #40Composite materials

2Productivity

If tomato varieties with enhanced disease resistance are developed, then yield and fruit quality improve, but breeding time and resource investment increase

Engineering Contradiction:

ImproveyieldVSAvoidbreeding time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting parental lines that already possess specific disease resistances (ToBRFV, nematode resistance, Fusarium resistance, mosaic virus resistance) before hybridization. This preliminary characterization of parental traits accelerates the breeding process and reduces the time required to develop varieties with enhanced productivity and yield.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If tomato varieties are bred for resistance to multiple pathogens, then fruit quality and yield stability improve, but genetic uniformity becomes more difficult to maintain

Engineering Contradiction:

Improveyield stabilityVSAvoidgenetic uniformity

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent segments the complex trait of multi-pathogen resistance into distinct resistance components (ToBRFV resistance, nematode resistance, Fusarium resistance, mosaic virus resistance), each contributed by specific parental lines. This segmentation allows for systematic breeding and maintenance of genetic uniformity while achieving comprehensive disease resistance and yield stability.

Inventive Principle:

Principle #1Segmentation
