Abstract

A new and distinct variety of yellow peach tree denominated ‘CRISPDANNA’ which has fruits with high eating quality and very long shelf life without alteration before and after harvesting, with a semi-sweet orange yellow flesh at maturity time, and a red pigmentation into and radiating around the stone cavity, and an attractive skin with a high percentage of luminous purple red blush on skin surface, on a red to orange red background.

Description

Botanical classification: Prunus persica (L.) Batsch.

Variety denomination: ‘CRISPDANNA’.

This application claims priority of Community Plant Variety Right No. 2022/2712 filed on Nov. 29, 2022 (11/29/2022) which is hereby incorporated by reference in its entirety.

The new variety named ‘CRISPDANNA’ is also known as 07.08.124.18 PJ or ASF2015. Indeed, before giving a name to a new and distinct variety of fruit tree, a provisional reference is assigned, considering the references of a tree in orchard. This provisional reference is constituted firstly with the number of the parcel on which the tree has grown, then the number of the line, the tree number and finally the year of selection. Then before being named ‘CRISPDANNA’, the provisional reference of this yellow peach tree variety was 07.08.124.18, corresponding to the tree 124 located in line 08 of the parcel 07 and selected during the year 2018. The letters “PJ” are related to the first letters of the type of tree in French (PJ for “Peach Jaune”, that means “yellow peach”). Once the hybrid selected, the breeder assigned a clone reference that begins with the letters “ASF” followed by the year of selection and a number corresponding to the maturity order. The final name is only assigned once the application has been filed and the name approved after its publication in the official bulletin. For the variety ‘CRISPDANNA’, the clone reference was ‘ASF2015’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of yellow peach tree, Prunus persica (L.) Batsch, which has been given the variety denomination ‘CRISPDANNA ’.

This new tree produces fruits with a long shelf life without alteration both on the tree after growth completion and after harvesting, very good eating quality, semi-clingstone orange yellow flesh fruits, generally with a red pigmentation under the skin of the fruit, for fresh market at the end of July or early in August in the Pyrénées-Orientales department, France.

ORIGIN OF THE VARIETY

The ‘CRISPDANNA’ yellow peach tree originated from 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 ‘CRISPDANNA’ variety results from a controlled pollinated cross between the yellow peach variety named ‘CRISPONDA’ (U.S. Plant Pat. No. 28,774) which was used as the seed parent, or female parent, and the yellow peach variety named ‘CRISPGOUDE’ (not patented) which was used as the pollen parent, or male parent.

The ‘CRISPDANNA’ variety was obtained by hybridizing and propagated by grafting on a ‘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 ‘CRISPDANNA’ yellow peach tree blooms at the middle or at the end of February near Elne in the Pyrénées-Orientales department, France. The blooming period is considered medium. However, it was observed that its date of blooming seems to be highly dependant on climatic conditions.

The first fruit of ‘CRISPDANNA’ ripens generally medium in the season, namely during the last two weeks of July. However, it was observed that its date of maturity seems to be highly dependant on climatic conditions.

DETAILED BOTANICAL DESCRIPTION

The trees, flowers, and fruits may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruits by ‘CRISPDANNA’ is high, due to fruit very long shelf life without alteration after harvesting.

Trees are medium to strong vigorous and large stature half-standing in a semi-flared 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 starts during February. The type of flower is campanulate with small petal size. Petals are dark pink or violet pink. Leaf glands are present and reniform. The fruit flesh is orange yellow at complete maturity. The fruit flesh usually shows a red pigmentation under the skin, into the stone cavity and radiating around the stone cavity. The fruit skin is thin, with a luminous purple red blush on a red to orange red background. The stone is semi-clingstone and its size is medium. Fruit taste is semi-sweet and aromatic.

Compared to ‘NECTAREINE’ yellow nectarine variety (U.S. Plant Pat. No. 22,493), the fruits of ‘CRISPDANNA’ usually ripen approximately during the same period, namely at the end of July. It should also be noted that the new ‘CRISPDANNA’ variety corresponds to a yellow peach, whereas fruits of the similar variety ‘NECTAREINE’ are yellow nectarines. The flowers of the new variety ‘CRISPDANNA’ usually bloom a few days later than the flowers of ‘NECTAREINE’. The flower type of the new variety ‘CRISPDANNA’ is campanulate, whereas the flower type of the ‘NECTAREINE’ variety is rosette. In addition, the fruits of the new variety ‘CRISPDANNA’ show a red color of their skin which is darker than the red color of the ‘NECTAREINE’ fruits.

Compared to its seed or female parent, i.e., the ‘CRISPONDA’ (U.S. Plant Pat. No. 28,774) variety, the fruits of the new variety ‘CRISPDANNA’ ripen approximately six weeks later. The flowers of ‘CRISPDANNA’ bloom approximately ten days after the flowers of ‘CRISPONDA’.

Compared to its pollen or male parent ‘CRISPGOUDE’ (not patented), the fruits of the new variety ‘CRISPDANNA’ ripen approximately at the same period, or a few days later. The flowers of ‘CRISPDANNA’ bloom a few days earlier than the flowers of ‘CRISPGOUDE’. Also, the ‘CRISPDANNA’ variety is not susceptible to corking, compared with its parent variety ‘CRISPGOUDE’. The fruit shape of ‘CRISPGOUDE’ is slightly rounder than the fruit shape of the new variety ‘CRISPDANNA’, which can be very slightly flattened.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of yellow peach 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 departement, 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 (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

TREE

• Size:
  • • Generally.—Considered large. The tree size the first year was approximately 200 to 280 cm in height. The tree was pruned during each following dormant season to a height of approximately 250 cm. Current season shoots growth could reach 80 cm in length. The tree size from the second year (second and next years) reached a final height of 330 cm including current season shoots length. The tree size is consistently reduced 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 to strong.
• Productivity: Considered good to very good, and regular. 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 fruits, significantly promotes fruit qualities, especially growth, color and firmness. Moreover, contamination risks due to monilia or rot are significantly reduced. ‘CRISPDANNA’ variety is not much sensitive to cracking of pistil cavity, to cork formation into peduncle cavity or to monilia.
• Bearer: Very regular. The fruit distribution is considered homogenous on mixed branches and spurs having more than 1 year. Thinning of 2 fruits out of 3 was necessary for the tree valorisation. Thinning was necessary every year during the years of observation.
• Form: The ‘CRISPDANNA’ variety has naturally a semi-flared shape.
• Density: Considered dense.
• Tree branching: Medium to strong.
• Hardiness: Hardy in all stone fruit growing areas of France and especially where the chilling requirement is between 700 and 1200 hours. More particularly, experimentations on the same orchard in Elne, Pyrénées-Orientales department, with winter chilling requirement below 7.2° C. comprised between 700 hours and 1200 hours according to the specificities of the year, namely 1031 hours in 2012-2013, 777 hours in 2013-2014, 893 hours in 2014-2015, 718 hours in 2015-2016, 825 hours in 2016-2017, 1017 hours in 2017-2018, 844 hours in 2018-2019, 706 hours in 2019-2020, 822 hours in 2020-2021, 700 hours in 2021-2022 and 919 hours in 2022-2023 showed a good behavior of the tree in all cases. No injury with temperatures as low as −12° C. in winter. Good resistance to late frosts.

• Crotch angles: Primary branches are considered variable, but the crotch angles are generally 45 degrees from the horizontal axis for current season shoots and 70° degrees from the horizontal axis for two year's old branches. This particular characteristic is not considered distinctive of the variety, however.
• Current season shoots:
• Internode length: Generally 22.0 to 28.0 millimeters.
  • • Color.—The color of new shoot tips is considered green (RHS Yellow Green 145 A) on lower part of new shoot tips, whereas the upper part is darker and colored in purple (RHS Greyed Purple 183 C), depending on the level on the tip and the sunlight exposure.
• Mature branches:
• Internode length: Generally 25.0 to 32.0 millimeters.
• Color of mature branches: Brown (RHS Grey Brown 199 A or RHS Grey Brown 199 B).

    • Color.—The kernel skin is light brown colored (RHS Greyed Orange 165 B). The almond, which is the seed of the kernel, is white (RHS White NN 155 A) and has a sweet taste. The kernel and its embryo are mature at the time of fruit maturity.
• Use: The subject variety ‘CRISPDANNA’ is considered to be a yellow peach tree having a medium season of maturity, and which produces fruits that are considered firm, attractively colored with a luminous purple red. Fruits have semi-sweet taste and are excellent for uncooked consumption, crunchy or melting when at full maturity. Fruits have excellent gustative qualities. 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. After harvest, fruits are well preserved more than 2 weeks at 2.0 degree Celsius.
• Shipping quality: Considered very good. The fruit of the new yellow peach 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 2 weeks-shipping at 2 degrees Celsius.
• Resistance to insects and disease: No particular susceptibilities were noted. The present variety is not very sensitive to Monilia or rot. The pistil cavity is completely closed, generally without any cork formation.

Although the new variety of yellow peach tree possesses the described characteristics when grown under the ecological conditions prevailing near Elne, Pyrénées-Orientales departement, 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.
