Description

This application claims priority of Community plant variety right No. 2005/0903 filed on May 18, 2005 which is hereby incorporated by reference in its entirety.

Botanical classification: Prunus persica L. Batsch—White Flat peach.

Variety denomination: ‘FLATPRINCESSE’.

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Prunus persica L. Batsch white flat peach tree. This new tree, named ‘FLATPRINCESSE’, produces very long lifetime, good eating quality, semi-freestone flesh fruit for fresh market in August in the 66 —Pyrénées Orientales departement—France. Contrast is made to ‘MAILLARFLAT’ flat peach, standard varieties, for reliable description. ‘FLATPRINCESSE’ is a promising candidate for commercial success in that it has a very high regular productivity and has the same well fruit quality as other varieties: ‘MAILLARFLAT’ (unpatented), ‘FLATPRETTY’ (pending U.S. Plant Pat. application No.11/434,796), ‘FLATQUEEN’ (pending U.S. Plant Pat. application No.11/434,799) and ‘FLATNICE’ (unpatented).

ORIGIN OF THE VARIETY

‘FLATPRINCESSE’ flat peach tree originated in a cultivated area of the south of France, in the 66 —Pyrénées Orientales department—France where it was tested. This place is under a Mediterranean climate in a temperate area characterized by irregular and low precipitation with drought in summer, high temperatures all year long.

The ‘FLATPRINCESSE’ variety was obtained by open-pollination of the ‘MAILLARFLAT’ (unpatented) variety. ‘FLATPRINCESSE’ was provisionally designated and tested as 02.03.21 PBPL and is registered at the Official Catalogue of the Agriculture Ministry of the French Republic December 29, 2004 under number 1016569. It was obtained from open-pollination and is propagated by grafting. It has been determined to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of standard rootstock on this scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree and the fruit were transmitted. The plant was reproduced asexually by us in Les Régalines, Route d'Alenya, La Prade de Mousseillous, 66200 ELNE, Pyrénées Orientales, France.

SUMMARY OF THE VARIETY

The new and distinct variety of ‘FLATPRINCESSE’ flat peach tree blooms in March at Perpignan in the Pyrénées Orientales departement, France. More particularly, it blooms at the same time as the MAILLARFLAT variety, between 7th and 21st of March.

The first fruit of ‘FLATPRINCESSE’ ripens in August, 18 days after ‘MAILLARFLAT’. More particularly, it approximately ripens between August 16th and 25th

DESCRIPTION OF THE DRAWINGS

In the accompanying drawing, which are as nearly true as it is reasonably possible to make in a colour illustration of this type:

FIG. 1 is a colour photograph which shows the flesh of the fruit of the new variety ‘FLATPRINCESSE’.

FIG. 2 is a colour photograph which shows a typical specimen of the fruit of the new variety ‘FLATPRINCESSE’.

 DETAILED BOTANICAL DESCRIPTION

The tree, flowers, and fruit may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruit by ‘FLATPRINCESSE’ is high, due to its fruit early ripening, and fruit evenness of maturity.

Trees are very vigorous and medium stature half-standing in a semi-upright out aspect. The flowering shoot is present excluding brushwoods side away from sun. Flowering begins semi-late in springtime. The type of flower is with relative medium petal size. Petals are Medium Pink. Three or four leaf glands are present and reniform. Time of maturity for consumption is late. The fruit flesh is white and its skin present a red-blush color. The stone is small size and the flesh is semi-clingstone.

Compared to ‘MAILLARFLAT’ variety, ‘FLATPRINCESSE’ has an older time of maturity, 18 days later. Fruits are red coloured until over 90% of their skin instead of 60 to 70% for ‘MAILLARFLAT’ fruits. ‘FLATPRINCESSE’ presents more flowers, 45 flowers per meter instead of 40 flowers per meter for ‘MAILLARFLAT’. ‘FLATPRINCESSE’ fruit tastes the same as ‘MAILLARFLAT’, semi sweet and aromatic, although evenness of productivity is better and regular.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of flat peach tree, the following has been observed, if not differently specified, during the second fruiting season under the ecological conditions prevailing at the orchards located in Elne, in the Pyrénées Orientales departement, France. All observations have been done on rootstock cultivar. The rootstock was a ‘Franc Inra Montclar®’ (unpatented) tree. All major color code designations are by reference to The R.H.S. Color Chart (Fourth Edition) provided by The royal Horticultural Society of Great Britain.

TREE

  • Size:
      • Generally.—Considered medium to large as compared to other common commercial flat peach cultivars ripening in the middle season of maturity. The tree size the first year was approximately 280 cm. The tree was pruned during each following dormant season to a height of approximately 250 cm. Current season shoots growth could reach 80 cm. So the tree size from the second year (second and next years) reached a final height of 330 cm with current season shoots length comprised.
  • Spread: Approximately 200 cm with a cylindrical shape. The whole orchard was oriented to a central leader organisation, with tree lines spaced of 4.0 meters and trees spaced of 1.0 meter in a same tree line. As a result, the orchard contains 2500 trees by hectare.
  • Vigor: Considered very vigorous.
  • Productivity: Very Productive. Fruit set is spaced by thinning to develop the remaining fruit into the desired market sized fruit. The number of the fruit set varies with the prevailing climatic conditions, and cultural practices employed during the bloom period, and is therefore not distinctive of the present variety.
  • Bearer: Very regular. Fruit set has been heavy during the years of observation and thinning of 1 fruit on 3 was useful every year during the past 5 years. Fruit have an important magnifying potential.
  • Form: The ‘FLATPRINCESSE’ variety has naturally a semi-upright shape.
  • Density: Considered dense.
  • Hardiness: The present tree was grown and evaluated in France. The variety appears to be hardy under typical central Pyrénées Orientales departement climatic conditions. Experimentations on different sites with winter chilling requirement comprised between 350 and 1200 hours showed a good behavior of the tree in all cases. Ascertained temperatures as low as −12 degrees Celsius caused no damages to the tree. The tree was also very resistant to frosty springtime weather.

TRUNK

  • Diameter: Approximately between 7.0 and 8.0 cm in diameter when measured at a distance of approximately 30 cm above the soil level.
  • Bark texture: Considered slightly rough, with folds of papery scarfskin being present.
  • Lenticels: Numerous lenticels are present. The lenticels range in size from approximately 0.5 cm in width, and from 0.1 to 0.2 cm in height.
  • Lenticel colour: The outside of lenticels has a silver-grey color (varying from RHS Grey 201 D to RHS Black 202 D), whereas the inside is considered brown (RHS Greyed Orange 166B).
  • Bark colouration: The bark has a silver-grey color a little darker than the lenticels (varying from RHS Grey 201 C to RHS Black 202 C).

BRANCHES

  • Size: Mature branches as well as current season shoots are medium to thick for the variety.
  • Diameter: Average as compared to other flat peach varieties. The current season shoots have a diameter from 4.0 to 12.0 millimeters, and branches of trees have a diameter comprised between 22.0 and 30.0 millimeters.
  • Surface texture: Average, wood which is several years old has no furrowed appearance.
  • Crotch angles: Primary branches are considered variable, but the crotch angles are generally around 70 degrees from the horizontal axis. This particular characteristic is not considered distinctive of the variety, however.
  • Current season shoots:
      • Surface texture.—Substantially glabrous.
  • Internode length: Generally 22.0 to 30.0 millimeters.
  • Colour of mature branches: Medium grey-brown (varying from RHS Grey Brown 199 C to B).
  • Current seasons shoots:
      • Colour.—The color of new shoot tips is considered a light green (varying from RHS Green 143 C to D) on lower part of new shoot tips, whereas the upper part is colored in reddish brown (varying from RHS Greyed Red 182 B to C), darkening when more exposed to the sun.

LEAVES

  • Size: Considered large for the species. Leaf measurements have been taken from vigorous, upright, current-season growth at approximately mid-shoot. The ratio leaf length/leaf width is around 4.
  • Leaf length: Approximately 170 to 190 millimeters without the petiole.
  • Leaf width: Approximately 40 to 50 millimeters.
  • Leaf base shape: Concave.
  • Leaf form: Lanceolate.
