Description

Latin name of the genus and species claimed: Prunus persica var. nucipersica.

Variety denomination: ‘SUNECT29’.

BACKGROUND AND SUMMARY OF THE INVENTION

This application relates to the discovery and asexual propagation of a new and distinct variety of nectarine, Prunus persica var. nucipersica cv. ‘Sunect29’. The new variety was first originated by hybridization and identified in May 2019 by Terry A. Bacon and Terrence J. Frett as breeder number ‘NE2384’. The new variety was first evaluated by Terry A. Bacon and Terrence J. Frett near Wasco, Calif. in Kern County.

A new and distinct variety of nectarine tree, Prunus persica var. nucipersica, cv. ‘Sunect29’, is characterized by early ripening, circular fruit with a sweet to mid-acid flavor. The fruit is very large-sized, with very firm flesh that is semi-adherent to the stone.

The pollen parent is ‘Supechtwentytwo’ (U.S. Plant Pat. No. 30,979), and the seed parent is ‘PE1042’ (unpatented breeding selection). The parent varieties were first crossed in February 2016, the date of first sowing being February 2017 and the date of first flowering being February 2019. The new nectarine variety ‘Sunect29’ was first asexually propagated by Terry A. Bacon and Terrence J. Frett near Wasco, Kern County, Calif. in February 2020 by dormant grafting.

The new variety ‘Sunect29’ is distinguished from its seed parent, ‘PE1048’ in that the fruit of the new variety ripens about 19 days later than the fruit of the seed parent. The fruit of the new variety ‘Sunect29’ also has a higher brix at 15% compared to 12% for ‘PE1048’.

The new variety ‘Sunect29’ is distinguished from its pollen parent, ‘Supechtwentywo’ in that the fruit of the new variety ripens about 12 days later than that of the pollen parent. The new variety ‘Sunect29’ also has a larger fruit weight of 195 g compared to 180 g for ‘Supechtwentytwo’. The new variety ‘Sunect29’ also does not have pubescence like ‘Supechtwentywo’.

The new variety ‘Sunect29’ resembles ‘Zee Fire’ (U.S. Plant Pat. No. 13,501) in that the fruit of both varieties have yellow flesh and ripen at about the same time. The new variety ‘Sunect29’ differs from ‘Zee Fire’ in that the fruit weight of the new variety is about 195 g compared to about 146 g for ‘Zee Fire’. The new variety ‘Sunect29’ also differs from ‘Zee Fire’ in that the fruit of the new variety has a brix of 15% and a Brix:Acid ratio of 20, compared to a brix of 13% and a Brix:Acid ratio of 10 for ‘Zee Fire’.

The new variety ‘Sunect29’ resembles ‘Sunectwentyone’ (U.S. Plant Pat. No. 18,114) in that the fruit of both varieties have yellow flesh. The new variety ‘Sunect29’ differs from ‘Sunectwentyone’ in that the fruit weight of the new variety is about 195 g compared to about 180 g for ‘Sunectwentyone’. The new variety ‘Sunect29’ also differs from ‘Sunectwentyone’ in that the ripening of the fruit of the new variety starts about 7 days later than ‘Sunectwentyone’.

The new variety ‘Sunect29’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, cuttings and grafting.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying color photographic illustration, FIG. 1, shows typical specimens of the foliage and fruit of the new nectarine variety ‘Sunect29’. The illustration shows the upper and lower surface of the leaves, an exterior and sectional view of a fruit divided across its suture plane to show flesh color, pit cavity and the stone. The photographic illustration was taken shortly after the fruit was picked and the colors are as nearly true as is reasonably possible in a color representation of this type.
