ABSTRACT:

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED
Prunus persica.
VARIETY DENOMINATION
‘Supechthirteen’.
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates to the discovery and asexual propagation of a new variety of clingstone peach,
Prunus persica
cv. ‘Supechthirteen’. The new variety was first hybridized by Carlos D. Fear in May 13, 1991. The new variety was selected and evaluated by Bruce D. Mowrey and David W. Cain, near Wasco, Kern County, Calif., the variety being originated by hybridization. The new variety is characterized by its early-ripening fruit with delicate flavor, its hardiness, self-fertility, and its low winter chilling requirement.
The seed parent is ‘Flordaprince’ (unpatented) and the pollen parent is ‘Earligrande’ (unpatented). The parent varieties were first crossed in February 1989. The date of sowing was November 1989, with the date of first flowering being February 1991. The new peach variety was first asexually propagated by Bruce D. Mowrey in June 1991, near Wasco, Kern County, Calif. by budding onto Nemared rootstock.
The new peach variety ‘Supechthirteen’ may be distinguished from presently available low-chilling cultivars in commerce by the following combination of characteristics: the new peach variety cv. ‘Supechthirteen’ most nearly resembles ‘Flordaprince’. It differs from ‘Flordaprince’ by ripening approximately 7 days before ‘Flordaprince’ and has more (80-100%) red overcolor compared to ‘Flordaprince’ (70-90%) and the red overcolor is more evenly distributed and less striped than with ‘Flordaprince’. The new cultivar vaguely resembles ‘Tropic Beauty’ but ripens approximately 17 days before ‘Tropic Beauty’.
The new peach cultivar, ‘Supechthirteen’ may be distinguished from its pollen parent ‘Earligrande’ (unpatented) in the following characteristics: the new cultivar ripens approximately 10 days before ‘Earligrande’. The new cultivar has a lower winter chilling requirement, requiring approximately 150 hours of temperature below 45° F. vs 250 hours for ‘Earligrande’. The new cultivar also has more (80-100%) external red blush than ‘Earligrande’ (40-60%).
The new peach variety cv. ‘Supechthirteen’ has been shown to maintain its distinguishing characteristics through successive asexual propagations, for example, by budding. The first propagation was performed near Wasco, Kern County, Calif. on June 1991 by Bruce D. Mowrey by budding onto Nemared rootstock.
