Abstract

A new and distinct variety of white flat nectarine tree, denominated ‘CAKEDELICE’, has flat fruits of very long shelf life without alteration before and after harvesting, and with a semi-sweet white flesh of high eating quality, with a slightly red pigmentation into and around the stone cavity, and an attractive luminous and homogenous purple red skin on a red background.

Description

Botanical classification: Prunus persica var. nucipersica.(L.) Batsch.

Variety denomination: ‘CAKEDELICE’.

This application claims priority of Community plant variety right No. 2012/0745 filed on Apr. 2, 2012 (Apr. 2, 2012), which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of white flat nectarine tree, Prunus persica var nucipersica (L.) Batsch, which has been given the variety denomination ‘CAKEDELICE’. This new tree produces fruit with a long shelf life without alteration both on the tree after growth completion and after harvesting, very good eating quality, semi-clingstone white flesh fruits for fresh market early in August in the Pyrénées-Orientales department (an administrative district), France. Contrast is made to its parents ‘ASFNBF0688’ (U.S. Plant Pat. No. 22,492) white flat nectarine variety and ‘NECTARMAGIE’ (U.S. Plant Pat. No. 17,579) white nectarine tree for reliable description. ‘CAKEDELICE’ is a promising candidate for commercial success in that it has very attractive fruits with very long shelf life without alteration before after harvesting.

ORIGIN OF THE VARIETY

The ‘CAKEDELICE’ white flat nectarine tree originated in a cultivated area of the south of France, in the Pyrénées-Orientales department, where it was tested.

This place is under a Mediterranean climate (a temperate area), on the Mediterranean coastline. Winters are gentle and summers warm and dry. The amount of days with temperatures below 7° Celsius can vary between 600 and 1200 hours per year. The place is sunny, with 2400 to 2800 hours of sunny days per year on average. The prevailing wind is called ‘Tramontane’: it dries the air, clears the sky from clouds, but its intensity can be strong and affect the harvest, fruit quantity and/or quality. Marine moisture does not affect the place. Precipitations are irregular through the year and from one year to another. The amount of rainy days does not exceed 80 days per year, and are mostly found in Spring and Autumn. In May and October, very intense precipitations occasionally happen. Summer is dry with a few thunderstorms.

The ‘CAKEDELICE’ variety resulted from a pollinated cross between the ‘NECTARMAGIE’ (U.S. Plant Pat. No. 17,579) white nectarine tree, which was used as the seed parent, and the ‘ASFNBF0688’ (U.S. Plant Pat. No. 22,492) white flat nectarine tree, which was used as the pollen parent.

‘CAKEDELICE’ was provisionally designated, tested and genetically identified by a genetic profile, under number 03.5E.125NBPL and was registered at the Official Catalogue of the Agriculture Ministry of the French Republic on Nov. 27, 2011 under number 4049391. The ‘CAKEDELICE’ variety was obtained by hybridizing and propagated by grafting on an ‘INRA GF677’ (non-patented) rootstock trees. 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 the standard rootstock trees set forth above on the 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. More particularly, the plant was reproduced by grafting.

SUMMARY OF THE VARIETY

The new and distinct variety of white flat nectarine tree blooms at the end of February or in March in the Pyrénées-Orientales department, France. More particularly, it blooms between February 28^th and March 17^th, generally 3 days earlier than ‘ASFNBF0688’ (U.S. Plant Pat. No. 22,492). However, it was observed that its early date of blooming seems to be highly dependant on climatic conditions.

The first fruit of ‘CAKEDELICE’ nectarine tree ripens at the end of July or early in August, generally about one month earlier than ‘ASFNBF0688’ (U.S. Plant Pat. No. 22,492). More particularly, ‘CAKEDELICE’ variety approximately ripens between July 22^nd and August 4^th. However, it was observed that its early date of maturity seems to be highly dependant on climatic conditions.

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 ‘CAKEDELICE’ is high, due to fruit very long shelf life without alteration after harvesting.

Trees are medium vigorous and large stature half-standing in a semi-flared to semi-upright out aspect. The anthocyanic coloration of flowering shoot is present excluding brushwood side away from sun. The time of beginning of flowering is considered medium; flowering begins at the end of February or during March. The type of flower is showy with medium to large petal size. Petals are medium pink. Leaf glands are present and reniform. The fruit flesh is considered white with a slightly red pigmentation into and around the stone cavity. The fruit skin is thick and colored with a homogenous and luminous purple red blush on a red background. The stone is semi-clingstone, small in size and the flesh is adherent to semi-adherent depending on the fruit maturity. Fruit taste is semi-sweet, very aromatic and with a high level of sugars.

The new variety male parent, which is ‘ASFNBF0688’ (U.S. Plant Pat. No. 22,492) produces a considerable amount of white flat nectarine tree at the end of August or early in September. In comparison, ‘CAKEDELICE’ variety ripens approximately one month earlier, at the end of July or early in August as set forth above. Moreover, both varieties produce an important amount of showy flowers and have a very high rate of fruit set. ‘CAKEDELICE’ fruits have a good and homogenous presentation, round and regular shaped, with a closed pistil cavity, and without any cork formation. Indeed, the cork formation in the pistil cavity of nectarine flat variety is often the cause of conservation problem, therefore rot. Accordingly, a variety without formation/training or presence of cork will generally have better conservation and thus less sensitive to the development of rot. In comparison, ‘ASFNBF0688’ fruits possess a pistil cavity barely closes, with a little amount of cork, that could lead to a susceptibility to rot. ‘CAKEDELICE’ fruits are colored with a luminous red on the whole fruit skin compared to ‘ASFNBF0688’ fruit which are colored in red on a pink cream background.

The new variety female parent, which is ‘NECTARMAGIE’ (U.S. Plant Pat. No. 17,579), produces white nectarines early in July.

Compared to ‘Cakelove’ (U.S. Plant Pat. No. 24,107) white flat nectarine tree, ‘CAKEDELICE’ variety ripens approximately 2 weeks earlier than ‘Cakelove’, as set forth above. ‘CAKEDELICE’ fruits show a size bigger than ‘Cakelove’ fruits.

Pistil cavity of ‘CAKEDELICE’ varieties are considered more closed than the ‘Cakelove’ pistil cavity.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of white flat nectarine tree, the following was observed on trees in their fourth growing season (third year of production) under the ecological conditions prevailing at the orchards located near the town of Elne, Pyrénées-Orientales department, France. All observations have been done on rootstock cultivars. Used rootstocks were ‘INRA GF677’ (non-patented) trees. All major color code designations are by reference to The R.H.S. Colour Chart 2001 (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

• Tree:
  • • Size.—Generally. — Considered large. The tree size the first year was approximately 250 cm. The tree was pruned during each following dormant season to a height of approximately 250 cm. Current season shoots growth could reach 60 to 80 cm. The tree size from the second year (second and next years) reached a final height of 310 to 330 cm with current season shoots length comprised. The tree size is consistently reduces to 250 cm the next years.
    • Spread.—Approximately 100 cm with a cylindrical shape. The whole orchard was oriented to a central leader organization, with tree lines spaced of 4.0 meters and trees spaced of 1.0 meter in a same tree line. As a result, tree spread was about 100 cm and the orchard contained 2500 trees by hectare.
    • Vigor.—Considered medium 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. A reduce vegetation, obtained with pruning or green pruning, approximately 1 month or 1 month ½ before harvesting flat fruits, significantly promotes fruit qualities, especially growth, color and firmness. Moreover, contamination risks due to Monilia or rot are significantly reduced. ‘CAKEDELICE’ variety is not much sensitive to cracking of pistil cavity, to cork formation into peduncle cavity or to Monilia.
    • Bearer.—Very regular. Thinning of 1 fruit out of 3 was necessary for the tree valorisation. Thinning was necessary every year during the years of observation.
    • Form.—The ‘CAKEDELICE’ variety has a naturally semi-spread to semi-upright shape.
    • Density.—Considered dense.
    • Hardiness.—The present tree was grown and evaluated in France. The variety appears to be hardy under the central Pyrénées-Orientales department typical climatic conditions. Experimentations on different sites with winter chilling requirement comprised between 350 hours and 1200 hours showed a good behaviour of the tree in all cases. Traditionally, flat fruits are more sensitive to critical low temperatures and to climatic variations, because of the flower morphology in which the ovule is less protected than in the classical round fruits. Thus, areas not much exposed to frost are recommended for peach trees growth. However ‘CAKEDELICE’ trees seem to be very resistant to critical frosty weather.

• Use: The subject variety ‘CAKEDELICE’ is considered to be a white flat nectarine tree with a mid-season maturity, and which produces fruits that are considered firm, attractively and luminously colored. Fruits have a semi-sweet taste and are excellent for uncooked consumption, crunchy or melting and juicy when at full maturity. Fruits have excellent gustative qualities. In particular, ‘CAKEDELICE’ fruits are very easy to eat, with their doughnut shape. Moreover, the non pointed stone shape is reassuring, especially for parents, and thus, there is no need to cut the fruit before eating. Due to their flesh quality, firmness and density, they can also be commercialized as 4^th range product (packed fruit or fruit in bags for example). And they are also useful for both local and very long distance shipping.
• Keeping quality: Remarkable. Fruits have a slow maturation and a long shelf life both on the tree after growth completion and after harvesting without alteration. After growth completion fruits are preserved more than one week on the tree. After harvest, fruits are well preserved more than 4 weeks at 2.0 degree Celsius.
• Shipping quality: Considered very good. The fruit of the new white flat nectarine variety showed minimal bruising of the flesh or skin damage after being subjected to normal harvesting and packing procedures. Its resistance to handling during harvest and packing and its long shelf life without alteration after harvest easily permit at least 4 weeks-shipping at 2 degrees Celsius.
• Resistance to disease: No particular susceptibilities were noted. The present variety is not very sensitive to powdery mildew and Monilia, or conservation diseases and decay due to its thick and strong skin.

Although the new variety of white flat nectarine tree possesses the described characteristics when grown under the ecological conditions prevailing near Elne, Pyrénées-Orientales department, France, it should be understood that variations of the usual magnitude and characteristics incident to changes in growing conditions, fertilization, pruning, pest control and horticultural management are to be expected.
