FLATWO White Flat Peach Tree Breeding for Early Ripening and Shelf Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of white flat peach tree that produces fruits with a long shelf life, early maturity, and high commercial potential, capable of thriving in Mediterranean climate conditions with variable weather patterns, while being resistant to frost and climatic variations.
Innovation Solution
The 'FLATWO' white flat peach tree, resulting from a cross between the white nectarine variety 'ASF 0621' and 'FLATREINE', is grafted onto 'INRA® GF677' rootstock, exhibiting early blooming, vigorous growth, and producing semi-clingstone fruits with a long shelf life, high sugar content, and resistance to frost, making it suitable for fresh market production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the peach tree is bred for early maturity, then the ripening time is reduced, but the shelf life may be compromised
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific genetic traits that independently control ripening time and shelf life. The 'FLATWO' variety achieves early maturity (June 1-22) while maintaining extended shelf life through controlled physiological parameters inherited from parent varieties, resolving the trade-off between speed of maturation and post-harvest durability.
2Strength
If the peach tree is bred for firm flesh, then the shipping quality is improved, but the eating quality may be reduced
Solution Approach 1:
The patent applies local quality by differentiating flesh characteristics in different regions of the fruit. The 'FLATWO' variety exhibits firm flesh in the core region for shipping durability, while maintaining softer, more aromatic characteristics near the skin and stone interface for superior eating quality. This spatial differentiation of tissue properties resolves the contradiction between transport robustness and culinary appeal.

AI summary
A new and distinct variety of white flat peach tree denominated ‘FLATWO’ which have fruits with high eating quality, an early ripening time and a very long shelf life without alteration before and after harvesting, the fruits having a semi-sweet white flesh, with a slightly red pigmentation when the fruits reach their maturity, and an attractive skin with a high percentage of purple red blush on skin surface, on a marbled orange red background.
