Seedless Grapevine Breeding via Embryo Rescue and Local Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Vitis vinifera grapevine variety that combines high production, desirable fruit characteristics, and resistance to environmental stresses such as cold, drought, and heat, while maintaining excellent handling and shipping qualities.
Innovation Solution
The development of the 'ARDTHIRTYSEVEN' grapevine variety, created through deliberate cross-breeding of GAW 5 and 1A-46+0, which produces attractive, crunchy, seedless berries with a creamy green skin, high yield, and excellent storage and shipping properties, and has demonstrated resistance to diseases and environmental stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If deliberate cross-breeding is used to create new grapevine variety, then unique genetic qualities and desirable fruit characteristics are achieved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action through embryo rescue technology, where embryos are extracted and cultured in vitro before full maturation. This allows the breeding process to bypass the lengthy natural development period, significantly reducing the time required to obtain new varieties while maintaining the genetic benefits of cross-breeding.
2Productivity
If high fertility parent variety is used, then fruit production increases, but seed presence reduces dessert quality
Solution Approach 1:
The patent applies the extraction principle by removing seeds from the fruit through selective breeding and embryo rescue. The high fertility parent GAW 5 provides abundant fruit production, while the breeding process extracts and eliminates the seed-bearing characteristics, resulting in seedless grapes that maintain high yield while improving dessert quality.
3Ease of operation
If thin skin variety is used, then natural sweet flavor is enhanced, but handling and shipping qualities deteriorate
Solution Approach 1:
The patent applies local quality by combining different parental characteristics in specific ways. The male parent 1A-46+0 contributes thin skin and natural sweet flavor, while the female parent GAW 5 contributes meaty texture and structural integrity. The hybrid ARDTHIRTYSEVEN exhibits localized thin skin for flavor while maintaining overall firmness for handling, achieving both dessert quality and shipping durability.

AI summary
A new distinct variety of grapevine named ‘ARDTHIRTYSEVEN’ abundantly forms attractive crunchy seedless berries with a creamy green skin coloration; lax and medium sized clusters which display an aromatic flavor. The fruit commonly is ready for harvesting during July in San Joaquin Valley of Central California, U.S.A, and displays good eating qualities as a table grape. The fruit firmness renders the fruit well amenable for handling, shipping, and storage.
