Solution Overview

Problem

There is a need for a new cultivar of grapevine that produces large, red, seedless berries with neutral flavor, early ripening, and high fruitfulness, addressing the limitations of existing cultivars such as 'Scarlet Royal' which are astringent at full ripeness and have a muscat flavor.

Innovation Solution

The development of a new grapevine cultivar named 'SV36-19-424', resulting from a cross between 'SV13-2-138' and 'SV28-100-202', characterized by perfect flowers, red berries with neutral flavor, and early ripening in mid-August, exhibiting vigorous growth and high fruitfulness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If grapevine cultivar 'Scarlet Royal' is used, then large red berries are produced, but the berries are astringent at full ripeness

Engineering Contradiction:

Improveberry sizeVSAvoidastringency

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by selecting and breeding for specific genetic traits that alter the chemical composition of the berries. The new cultivar 'SV36-19-424' was developed through controlled crossing and selection to achieve neutral flavor without astringency while maintaining large berry size, effectively changing the biochemical parameters of the fruit

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If grapevine cultivar 'Scarlet Royal' is used, then large red berries are produced, but the berries have muscat flavor

Engineering Contradiction:

Improveberry sizeVSAvoidmuscat flavor

Core Design Contradiction:

Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The breeding program targeted specific flavor profile parameters by selecting parent plants with desirable traits and screening offspring for neutral flavor. The resulting cultivar 'SV36-19-424' exhibits neutral flavor without muscat characteristics while maintaining the large berry size of commercially viable varieties

Inventive Principle:

Principle #35Parameter changes

3Reliability

If traditional grapevine breeding is used, then new cultivars are developed, but the process requires multiple generations and extensive field testing

Engineering Contradiction:

Improvecultivar stabilityVSAvoidbreeding cycle duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent employs preliminary action through in vitro embryo culture technology, allowing the development of haploid plants from pollen grains. This enables early generation selection and accelerates the breeding process by producing fixed-heterozygous lines in fewer generations, reducing the time required for stable cultivar development

Inventive Principle:

Principle #10Preliminary action

AI summary

A new and distinct variety of grapevine plant named ‘SV36-19-424’ particularly characterized by its very sweet, crisp, red berries with neutral Vitis vinifera flavor. Natural cluster size is medium with well-filled, loose clusters. Fruitfulness is high with shoots on spur pruned vines usually producing one flower cluster per shoot.
