Grapevine Breeding for Early Uniform Firm Table Grapes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new grapevine variety that can thrive in temperate regions with specific climate and growing conditions, producing early ripening, very fertile, uniform, and attractive berries with firm, crunchy skin, and consistent fruit production.
Innovation Solution
The development of the new grapevine variety 'IVC AN1', which is a result of controlled breeding, characterized by medium vigor, erect growth habit, and specific berry and leaf traits, including a vivid greenish yellow color, medium size clusters, and aromatic taste, adapted to temperate climates with average yearly temperatures around 19°C and minimum winter temperatures of -10°C.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If early ripening is achieved through selective breeding, then the ripening time is reduced, but the berry size and weight may be compromised
Solution Approach 1:
The patent applies parameter changes by selectively breeding the grapevine to optimize multiple parameters simultaneously - reducing ripening time while maintaining or enhancing berry weight (1.5-2.5g) and size. The variety 'IVC AN1' achieves medium-to-late ripening (August-September) with large, heavy berries through controlled modification of growth and development parameters.
2Productivity
If very fertile variety is developed, then the fruit production consistency is improved, but the plant vigor may increase excessively
Solution Approach 1:
The patent applies parameter changes by balancing fertility and vigor through selective breeding. The variety 'IVC AN1' exhibits medium plant vigor combined with very high fertility, achieving consistent fruit production without excessive vegetative growth. This optimization of the fertility-vigor parameter balance allows for reliable commercial production.
3Manufacturing precision
If uniform berry size and shape are achieved, then the aesthetic appeal is improved, but the genetic complexity increases
Solution Approach 1:
The patent applies parameter changes by stabilizing berry morphology parameters through selective breeding. The variety 'IVC AN1' produces uniformly ovoid berries with consistent dimensions (25-35mm length, 20-30mm diameter) and uniform golden-green coloration. This genetic stabilization of morphological parameters achieves commercial uniformity without requiring complex genetic modifications.
4Ease of operation
If firm berry with tender crunchy skin is developed, then the eating quality is improved, but the skin thickness may increase
Solution Approach 1:
The patent applies parameter changes by optimizing the relationship between skin thickness and flesh texture parameters. The variety 'IVC AN1' produces berries with firm flesh and tender crunchy skin that provides excellent eating quality. The skin thickness is optimized to be sufficient for firmness and shipping durability while remaining thin enough to allow the characteristic crunchy texture when eaten.

AI summary
This invention relates to a new and distinct variety of grapevine plant named ‘IVC AN1’. The new variety is primarily adapted to the growing conditions of the temperate or dry areas, e.g. southern Italy, with low rainfall and low disease pressure (namely downy mildew), with winter minimum temperatures down to 10° C., and is characterized by attractive berries with vivid greenish yellow color which are uniform in size and shape and are firm with tender crunchy skin.
