FLATDIVA White Flat Peach Tree Late Ripening Shelf Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a white flat peach tree variety that produces fruits with a long shelf life, excellent eating quality, and is resistant to climatic variations, with a specific ripening time that allows for optimal fresh market availability in late summer or early fall.
Innovation Solution
The 'FLATDIVA' white flat peach tree, resulting from a cross between 'FLATSTAR' and 'NECTARFLORA', exhibits unique characteristics such as late ripening, high sugar content, and resistance to climatic conditions, with a grafting method on 'INRA® GF677' rootstock, ensuring consistent fruit quality and long shelf life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the peach tree variety is selected for early ripening, then market availability is improved, but shelf life and resistance to climatic variations deteriorate
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a specific variety (FLATDIVA) with optimized physiological parameters including sugar content (17-19° Brix), acidity (6-9 meq/100ml), and ripening characteristics. The variety is grown on specific rootstock (INRA GF677) to achieve the desired balance between ripening time and shelf life, with fruits ripening late season (August 12 to September 2) to extend market availability while maintaining quality.
Solution Approach 2:
The patent uses asexually propagated plants (grafting) to create copies of the FLATDIVA variety that remain true to the original tree characteristics. This ensures consistent fruit quality, sugar content, and shelf life across multiple generations, allowing the variety to be replicated commercially without the variations that would occur with sexual reproduction.
2Manufacturing precision
If the peach tree variety is selected for high sugar content and excellent eating quality, then fruit quality is improved, but productivity and yield may deteriorate
Solution Approach 1:
The patent applies local quality by focusing on specific fruit characteristics (semi-clingstone white flesh, greenish color with red pigmentation around stone cavity, high sugar content 17-19° Brix, acidity 6-9 meq/100ml) while maintaining overall tree health and productivity. The variety FLATDIVA is specifically selected for these quality attributes, and the rootstock INRA GF677 is chosen to support both quality production and reasonable yield.
3Duration of action of stationary object
If the peach tree variety is selected for late ripening, then shelf life is improved, but market availability window may deteriorate
Solution Approach 1:
The patent uses parameter changes to optimize the ripening window by selecting a variety that ripens late season (August 12 to September 2) under Mediterranean climate conditions. This timing extends the shelf life while ensuring the fruits are available for the fresh market at the optimal time (end of August or early September in Pyrénées-Orientales department, France).
