1. A new and distinct variety of Peach Tree substantially as illustrated and described herein.

Classification: The present invention relates to a new Prunus persica (L.) Batsch--Peach.

Variety denomination: The new plant has the varietal denomination `Platañomel`.

The new variety of Peach tree was created in a breeding program by crossing two parents; in particular, by crossing as seed parent a variety designated `89-062` (unpatented) and as pollen parent a variety designated `89-067` (unpatented). Both, female and male, are components of a parent collection from a selection made between plants issued from seeds got in a free pollination in a population of different origin done in 1989. Both parental varieties are property and have not been commercialized.

The seeds resulting from this controlled hybridization were germinated in a greenhouse in the spring of 1995 and planted in a field on the farm of La Mogalla in Cartaya (Huelva), Spain, 7°CW., 37°CN., 45 feet elevation. The seedlings fruited during the spring of 1997, one of which designated as `95.04.002-P,` (unpatented) was selected for its low chilling requirements (250 to 300 hours), early ripening, attractive fruit shape and color. The new variety produces high firm fruit with yellow flesh of good fruit quality. During 1998, the original plant selection was asexually propagated at the above noted location by budding onto a standard Peach rootstock variety designated as `GF-677` (non patented) and a test plot of 4 plants was established.

The new variety has been asexually multiplied several times since 1999 at this location by budding onto the standard Peach rootstock `GF-677` (unpatented) and no incompatibility with the Peach rootstock has occurred following budding. During all asexual reproduction, the characteristics of the original plant have been maintained and no aberrant phenotypes have appeared.

The new variety is characterized as to novelty by producing clingstone fruit having an early season ripening date and a low chilling requirement (250 to 300 hours). Fruit of `Platañomel` are ripe for commercial harvesting and shipment between approximately May 5th to May 15th. These harvesting dates are approximately 12 to 15 days earlier than the harvest dates for the commercial Peach variety `May Crest` (unpatented) , and approximately 7 days earlier than the harvest dates for the commercial Peach variety `Rich May` (U.S. Plant Pat. No. 7,432)

`Platañomel` differs from Peach trees of `May Crest` (unpatented) and `Rich May` (U.S. Plant Pat. No. 7,432) by its fruit size and shape.

`Platañomel` produces larger, rounded shaped fruit with a slight apical tip; whereas the fruit of `May Crest` are smaller and have a more pronounced apical tip.

The new variety has rounded leaf glands; whereas, the leaf glands of `May Crest` are reniform.

The fruit of `Platañomel` are more rounded in shape with a slight apical tip; whereas the fruit shape of `Rich May` is ovoid with a strong apical tip.

The fruit surface of `Platañomel` is covered, almost 100%, with a brilliant dark red color; whereas the fruit surface of `Rich May` is covered approximately 85% to 90% with a deep red over yellow color.

The new variety produces more homogenous size fruits with a low chilling requirement (250 to 300 hours) ; whereas `Rich May` has a chilling requirement of 800 to 900 hours.

The accompanying photographic illustrations show typical specimens of the new variety as true to color as is reasonably possible to make in illustrations of this character.

FIG. 1 shows typical flowers of the new variety.

FIG. 2 shows the coloration of dorsal and ventral leaves of the new variety.

FIG. 3 shows the external coloration of fruit of the new variety when sufficiently matured for harvesting and shipment.

FIG. 4 shows mature fruits of the new variety dissected in the equatorial plane illustrating the characteristics of the flesh and stone.

The following observations and descriptions are of the original seedling tree grown on its own root during the growing years of 1997 to 2001 at the orchard previously described, located near the town of Cartaya, Huelva, Spain. Plants described are from seed germinated in the Spring of 1995 with the trees then planted in a field in December 1995. Fruit was first observed in Spring 1997.

In this description, it is to be understood that references made to dimensions, sizes, colors, etc. of the botanical and phonological characteristics of the new variety are approximations of averages set forth as accurately as practical. Phenotypic expression may vary with light intensity and cultural and environmental conditions. The color references used in this description, are to The Royal Horticultural Society Colour Chart (R.H.S.C.C.) and terminology used in the color descriptions herein refers to plate numbers in said color chart.
