DETAILED BOTANICAL DESCRIPTIONCHARACTERIZATION OF ANDES NEC-5 NECTARINE

(9) Color descriptions below are based on evaluations with a Minolta CR-400 colorimeter al CIE D65/0 illumination/viewer conditions. The color parameters correspond to the uniform color space CIELAB, derived from McGuire (1992). Two color coordinates, a* and b*, as well as a psychometric index of lightness, L*, are defined. The L* is a measurement of luminosity, i.e., the equivalence of each color on the gray scale, ranging from 0 (black) to 100 (White). The a* takes positive values (0 to +60) for reddish colors and negative values (0 to 60) for the greenish ones, whereas the b* takes positive values (0 to +60) for yellowish colors and negative values (0 to 60) for the bluish ones. This is much more precise and repeatable analysis of color than obtained by using color charts. Where a reasonably close match could be discerned, The Munsell Color Chart is also referenced. Tree: 1.

GENERAL TECHNICAL NOTES

(12) Very good outward appearance. Excellent color coverage. Fruit round, no tip. High productivity. Excellent flavor. After four years of evaluation, the variety continues to show its outstanding characteristics: very good productivity, good size, good flavor and good external appearance. The variety has a high potential for export to Asian countries because of its white flesh and its exceptional post-harvest life potential.
