Classification: The present invention relates to a new Prunus persica (L.) Batsch--Peach.
Variety denomination: The new plant has the varietal denomination `Plapiomel`.
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 `91-002` (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 and 1991. 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°C W., 37°C N., 45 feet elevation. The seedlings fruited during the Spring of 1997, one designated `95.03.003-P,` (unpatented) was selected for its low chilling requirement (250 to 300 hours) early to mid-season ripening, attractive fruit shape and color, yellow flesh, medium-high firm fruit, and good fruit quality. During 1998, the original plant selection was propagated asexually, at the above noted location, by budding onto standard Peach rootstock variety designated `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 variety designated as `GF-677` (unpatented) and no incompatibility with 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 Peach tree variety differs from its parents and other known cultivars of Peach Trees by producing clingstone fruits with a low chilling requirement (250 to 300 hours) and an early to mid-season ripening date. The fruits of the new variety are ripe for commercial harvesting and shipment between approximately May 30th to May 15th. These harvesting dates are approximately 25 days earlier than the harvest dates of the commercial Peach variety `Vista` (U.S. Plant Pat. No. 9,549), approximately 13 days earlier than the harvest dates of the commercial Peach variety `Redhaven` (unpatented), approximately 15 days earlier than the harvest dates of the commercial peach variety `Rich Lady` (U.S. Plant Pat. No. 7,290), and approximately 20 days later than the harvest dates of the commercial peach variety `Rich May` (U.S. Plant Pat. No. 7,432).
`Plapiomel` differs from Peach trees of `Vista,` `Rich May` and `Rich Lady` by its lower chilling requirement (200 to 300 hours); whereas `Vista` has a 700 to 800 hour chilling requirement; `Rich May` has a 800 to 900 hour chilling requirement; and `Rich Lady` has a 750 to 850 hour chilling requirement.
`Plapiomel` produces round shaped clingstone fruit with a slightly apical tip; whereas `Vista` produces semi-freestone fruit with an ovoid shape; `Rich May` produces more firm, ovoid shaped fruit with a strong apical tip. The fruit of `Rich Lady` also have an ovoid shape.
The surface of the fruit of the new variety is covered approximately 60% to 80% with a red over a yellow-greenish color; whereas 100% of the fruit surface of `Rich Lady` shows a red color.
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.
The following observations and descriptions are of plants grown at the orchard previously described, located near the town of Cartaya, Huelva, Spain. Observations were made of the original seedling tree on its own root during the growing years of 1997 to 2001. Plants described are from seed germinated in Spring of 1995 with the trees planted in a field in December 1995. First fruit was observed in Spring 1997.
In this description, it is to be understood that references of the 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.
