Abstract

A new and distinct variety of yellow nectarine tree denominated ‘NECTAMILA’ which has fruits with high eating quality, meaning a taste perception of high sugar content and developed aromas, and very long shelf life without alteration before and after harvesting, with a semi-sweet orange yellow flesh at maturity time, with varying degrees of red pigmentation depending on maturity, and an attractive skin with a very high percentage of luminous purple red blush on skins surface, on a red or orange red background.

Description

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

Variety denomination: ‘NECTAMILA’.

This application claims priority of Community Plant Variety Right No. 2022/2716 filed on Nov. 29, 2022 (11/29/2022) which is hereby incorporated by reference in its entirety.

The new variety named ‘NECTAMILA’ is also known as 24.01.59.15 NJ or ASF2024. 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 ‘NECTAMILA’, the provisional reference of this yellow nectarine tree variety was 24.01.59.15, corresponding to the tree 59 located in line 01 of the parcel 24 and selected during the year 2015. The letters “NJ” are related to the first letters of the type of tree in French (NJ for “Nectarine Jaune”, that means “yellow nectarine”). 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 ‘NECTAMILA’, the clone reference was ‘ASF2024’.

BACKGROUND OF THE NEW VARIETY

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

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, which means a taste perception of high sugar content and developed aromas, semi-clingstone yellow orange flesh fruits, with varying degrees of red pigmentation depending on the ripeness 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 ‘NECTAMILA’ yellow nectarine 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 ‘NECTAMILA’ variety results from a controlled pollinated cross between the white nectarine variety named ‘NECTARTIC’ (U.S. Plant Pat. No. 23,442) which was used as the seed parent, or female parent, and the white flat nectarine variety named ‘CAKELOVE’ (U.S. Plant Pat. No. 24,107) which was used as the pollen parent, or male parent.

The ‘NECTAMILA’ 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 ‘NECTAMILA’ yellow nectarine tree blooms 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 ‘NECTAMILA’ ripens generally medium in the season, namely in the 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 ‘NECTAMILA’ 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 typically starts at the end of February. The type of flower is showy (rosette) with medium petal size. Petals are pink. Leaf glands are present and reniform. The fruit flesh is yellow orange at complete maturity, with more or less red pigmentation depending on the ripeness of the fruit. The fruit skin is medium thick, 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, aromatic and with a high level of sugars.

Compared to ‘NECTAVANTOP’ yellow nectarine variety (U.S. Plant Pat. No. 22,493), the fruits of ‘NECTAMILA’ usually ripen approximately one week earlier than the fruits of ‘NECTAVANTOP’. Moreover, the fruit size of ‘NECTAMILA’ is slightly higher than the fruit size of the similar variety ‘NECTAVANTOP’. It should be noted that observations of fruit size can vary from one year to the next, depending, others, on growing conditions, specific features of the year especially regarding weather conditions, among other factors. It is however remarkable that, on average and considering equal conditions, the fruits of the new variety ‘NECTAMILA’ are higher in size than the fruits of ‘NECTAVANTOP’.

Compared to ‘NECTAREINE’ yellow nectarine variety (U.S. Plant Pat. No. 17,480), the fruits of ‘NECTAMILA’ ripens approximately at the same period. The flowering period of the new variety ‘NECTAMILA’ is however about ten days earlier than the flowering period of the similar variety ‘NECTAREINE’.

In addition, the fruit skin of the new variety ‘NECTAMILA’ has a darker and more purple-red color than the fruit skin of the similar variety ‘NECTAREINE’, the latter being light red. Particularly, the fruit skin of ‘NECTAMILA’ is much more colorful and has fewer lenticels than the fruit skin of ‘NECTAREINE’. The coloration of the fruit skin for the new variety is brighter and more uniformly colored. The fruit shape is rounder and more homogeneous for ‘NECTAMILA’. As a result of all the above, the fruit of the new variety has a better appearance than fruit of the ‘NECTAREINE’ variety.

Compared to its seed or female parent, i.e., the ‘NECTARTIC’ (U.S. Plant Pat. No. 23,442) variety, the new variety ‘NECTAMILA’ ripens usually approximately one month earlier. The flowering period of the new variety ‘NECTAMILA’ is similar to the flowering period of the parent variety ‘NECTARTIC’. It should also be noted that the new ‘NECTAMILA’ variety corresponds to a yellow nectarine variety, whereas the fruits of the parent variety ‘NECTARTIC’ have a white flesh.

Compared to its pollen or male parent, i.e., the ‘CAKELOVE’ (U.S. Plant Pat. No. 24,107) variety, the new variety ‘NECTAMILA’ ripens usually approximately ten days later. The flowering period of the new variety ‘NECTAMILA’ is also later than the flowering period of the parent variety ‘CAKELOVE’, by around two to three weeks. It should also be noted that the new ‘NECTAMILA’ variety corresponds to a yellow nectarine variety, whereas the ‘CAKELOVE’ variety corresponds to a white flat nectarine.

The new ‘NECTAMILA’ variety is thus distinguished from its progenitors by its subspecies, flowering date and ripening date.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of yellow nectarine tree, the following was observed on trees in their fourth growing season (third year of production), except for the observations on flower which were done in the third growing season, 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. ‘NECTAMILA’ 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 ‘NECTAMILA’ 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.

    • Dorsal edge.—Shape. — Grooved.
    • Stone color.—The color of the dry stone is generally considered brown (RHS Greyed Orange 164 A or RHS Greyed Orange 164 B).
    • Tendency to split.—Splitting is absent.
    • Kernel.—Size. — The kernel is considered medium. Length. — Approximately 15.0 millimeters. Width. — Approximately 10.0 millimeters. Thickness. — Approximately 5.0 millimeters. Form. — Considered elliptical. Pellicle. — The pellicle of the kernel has a short pubescence. 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 155 D) and has a sweet taste. The kernel and its embryo are mature at the time of fruit maturity.
    • Use.—The subject variety ‘NECTAMILA’ is considered to be a yellow nectarine 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. 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 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 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 nectarine 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.
