NECTARCIEL White Nectarine Tree Breeding for Shelf Life and Climate Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of white nectarine 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 'NECTARCIEL' white nectarine tree variety, resulting from hybridization with 'NECTARPERF' and propagated using 'INRA® GF677' rootstock, exhibits medium vigor, semi-clingstone fruits with a red pigmentation, and a medium to late blooming period, ensuring high potential for commercial production with resistance to cracking and disease, and a long shelf life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the nectarine variety is bred for long shelf life and good eating quality, then the fruit quality and storage duration are improved, but the productivity and resistance to climatic variations may be compromised
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific genetic traits that optimize the balance between shelf life and productivity. The 'NECTARCIEL' variety was developed with controlled parameters including medium vigor, medium to late blooming period, and specific fruit characteristics (firm texture, aromatic flavor, semi-sweet taste) that collectively achieve both long shelf life and good productivity under Mediterranean conditions
2Adaptability or versatility
If the nectarine variety is bred for resistance to climatic variations and disease, then the reliability and adaptability are improved, but the fruit quality and eating quality may be compromised
Solution Approach 1:
The patent applies local quality by developing region-specific adaptation for Mediterranean climates. The 'NECTARCIEL' variety was bred specifically for the Pyrénées-Orientales department conditions, with traits optimized for local climatic variations including heat tolerance, drought resistance, and adaptation to the Tramontane wind conditions, while maintaining high fruit quality standards
3Duration of action of stationary object
If the nectarine variety has medium vigor and medium to late blooming period, then the shelf life and resistance to climatic variations are improved, but the productivity and early season market availability may be compromised
Solution Approach 1:
The patent applies dynamics by creating a variety that adapts its phenological expression to environmental conditions. The medium to late blooming period of 'NECTARCIEL' is not fixed but dynamically adjusts based on climatic cues, allowing the tree to optimize between early season productivity and late season fruit quality with extended shelf life, particularly under Mediterranean climate variability

AI summary
A new and distinct variety of white nectarine tree denominated ‘NECTARCIEL’ which has fruits with high eating quality and very long shelf life without alteration before and after harvesting, with a semi-sweet white flesh and slightly greenish at maturity time, and 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 background.
