Solution Overview

Problem

There is a need for a new variety of white flat nectarine tree that can thrive in Mediterranean climates with variable weather conditions, offering fruits with a long shelf life, good eating quality, and resistance to climatic dependencies for commercial fresh fruit production.

Innovation Solution

The 'CAKEMOON' white flat nectarine tree, resulting from a controlled cross between 'CAKEDELICE' and 'NECTARPERF' trees, is grafted onto 'INRA® GF677' rootstock, exhibiting unique characteristics such as late blooming, medium to late fruit ripening, and high resistance to frost, with fruits having a long shelf life and excellent eating quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If early blooming varieties are used to extend the growing season, then the fruit production period is extended, but the variety becomes more sensitive to climatic variations and frost damage

Engineering Contradiction:

Improvegrowing season durationVSAvoidresistance to climatic variations

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

Instead of selecting for early blooming to extend the season, the invention inverts the approach by selecting for late blooming. The 'CAKEMOON' variety blooms later than conventional varieties, which naturally extends the growing season while avoiding early-season frost risks and climatic variability, thus achieving both extended season duration and improved reliability

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If thin skin fruits are cultivated to improve eating quality, then the fruit is more juicy and aromatic, but the shelf life is reduced and handling becomes more difficult

Engineering Contradiction:

Improveeating qualityVSAvoidshelf life

Core Design Contradiction:

Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The invention applies local quality by creating a differentiated skin structure: the outer skin remains thin enough to allow flavor development and aromatic quality, while the flesh beneath develops enhanced firmness and density. This localized differentiation enables the fruit to maintain excellent eating quality with thin skin characteristics while simultaneously achieving extended shelf life and improved handling properties

Inventive Principle:

Principle #3Local quality

3Productivity

If vigorous growth is promoted to increase fruit quantity, then productivity is improved, but the tree becomes more susceptible to disease and requires more intensive management

Engineering Contradiction:

Improvefruit quantityVSAvoiddisease susceptibility

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The invention changes the growth parameter from vigorous to moderate growth rate. The 'CAKEMOON' variety exhibits moderate, balanced growth that maintains sufficient fruit quantity and productivity while reducing canopy density and improving air circulation within the tree structure, thereby decreasing susceptibility to fungal diseases and reducing the need for intensive disease management interventions

Inventive Principle:

Principle #35Parameter changes

AI summary

A new and distinct variety of white flat nectarine tree denominated ‘CAKEMOON’ has fruits with high eating quality and very long shelf life without alteration before and after harvesting, with a very well closed pistil cavity, a semi-sweet white flesh with a red pigmentation around and into the stone cavity, and an attractive luminous skin with a very high percentage of purple red blush on skin surface, on a red background.
