Abstract
A new and distinct variety of nectarine tree ( Pruns var. nucipersica ). The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95 in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consists of the following unique combination of features that are desirable in a new variety: 1. Vigorous upright growth. 2. Regular and heavy production of fruit. 3. Late maturity of fruit. 4. Fruit with an attractive blush that partially covers a bright yellow ground color. 5. Large size of yellow flesh clingstone fruit. 6. Fruit with very good flavor and eating quality. 7. Fruit with firm flesh, good storage and shipping qualities. 8. Fruit that has the ability to remain firm on the tree 12 to 14 days after maturity, (shipping ripe).
