FLATHEART White Flat Peach Tree Shelf Life and Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of white flat peach tree that produces fruits with a long shelf life, good eating quality, and is suitable for commercial fresh fruit production, particularly in the Mediterranean climate of the Pyrénées-Orientales department in France, where climatic conditions can affect blooming and ripening dates.
Innovation Solution
The 'FLATHEART' white flat peach tree, resulting from a cross between the white nectarine variety 'NECTARRELIE' and the white flat peach variety 'FLATREINE', is propagated using 'INRA® GF677' rootstock trees, exhibiting unique tree and fruit characteristics such as medium vigor, regular fruit distribution, and resistance to climatic variations, ensuring consistent fruit quality and extended shelf life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If conventional peach varieties are grown in Mediterranean climate, then they can be cultivated in the region, but the fruit shelf life is short and quality deteriorates quickly after harvesting
Solution Approach 1:
The patent applies parameter changes by developing a new peach variety with fundamentally different physiological characteristics - specifically extended shelf life and improved quality consistency - through selective breeding that modifies the genetic parameters of the parent varieties to achieve these enhanced traits
2Duration of action of stationary object
If peach varieties are bred for extended shelf life, then storage duration is improved, but eating quality and flavor may be compromised
Solution Approach 1:
The breeding process achieves parameter changes by simultaneously optimizing multiple quality parameters - firmness, flavor, color, and texture - while extending shelf life, rather than sacrificing eating quality for storage duration
Solution Approach 2:
The variety combines beneficial traits from two parent varieties - the white nectarine 'NECTARRELIE' and the white flat peach 'FLATREINE' - creating a composite genetic structure that integrates both extended shelf life characteristics and superior eating quality attributes from each parent
3Stability of the object's composition
If peach trees are propagated to ensure true-to-type characteristics, then genetic consistency is maintained, but propagation complexity increases
Solution Approach 1:
The patent employs grafting propagation, a copying method where the scion (variety cutting) is graft onto compatible rootstock, creating genetically identical copies of the parent plant that maintain true-to-type characteristics while using a standardized, well-established propagation technique

AI summary
A new and distinct variety of white flat peach tree denominated ‘FLATHEART’ which have fruits with large size, high eating quality and very long shelf life without alteration before and after harvesting, with a semi-sweet cream white flesh which becomes pink at maturity time, and has a red pigmentation into and around the stone cavity, and an attractive skin with a high percentage of luminous purple red blush on skin surface, on a red to light red background.
