Description

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

Variety denomination: ‘0322E82NB’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of white nectarine tree, Prunus persica (L.) Batsch var. nucipersica., which has been given the variety denomination ‘0322E82NB’.

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, clingstone white flesh fruits with a slightly red pigmentation for fresh market mid-October in the Pyrénées-Orientales department, France.

ORIGIN OF THE VARIETY

The ‘0322E82NB’ white 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 ‘0322E82NB’ variety results from a pollinated cross between a white nectarine tree named 05.04.01NB ASF0635 (not patented) which was used as a seed parent and the ‘NECTARDREAM’ (U.S. Plant Pat. No. 23,420) white nectarine tree which was used as the pollen parent.

‘0322E82NB’ was provisionally designated, tested and genetically identified by a genetic profile, under number 03.22E.82.10.

The ‘0322E82NB’ variety was obtained by hybridizing and propagated by grafting on a “INRA GF677” 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 ‘0322E82NB’ white nectarine tree blooms mid-March near Elne in the Pyrénées-Orientales department, France. More particularly, in 2011, it bloomed between 10th and 19th of March, in 2012 between March 26th and April 4th. The blooming period is considered late to very late. However, it was observed that its late date of blooming seems to be highly dependant on climatic conditions.

The first fruit of ‘0322E82NB’ ripens generally in the beginning or middle of October. More particularly, it usually ripens between October 7th and October 12th. However, it was observed that its 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 fruits by ‘0322E82NB’ is high, due to fruit very long shelf life without alteration after harvesting.

Trees are 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 late to very late; flowering begins at the middle of March. The type of flower is showy with medium petal size. Petals are medium pink. Leaf glands are present and reniform. The fruit flesh is greenish white generally with a slightly red pigmentation into and in a star shape around the stone cavity. The fruit skin is very thick, with a luminous and homogenous red purple blush on a light red cream background. The stone is clingstone and its size is medium to large. Fruit taste is semi-sweet, very aromatic and with a high level of sugars.

Compared to ‘NECTARDUCHESSE’ variety (not patented), ‘0322E82NB’ variety blooms 6 days later and the fruits of ‘0322E82NB’ variety ripen 15 days later than ‘NECTARDUCHESSE’ fruits. The maturity of ‘0322E82NB’ variety is considered late.

The fruit color of the new ‘0322E82NB’ variety is more purple red on 80 to 85 percent of the skin, on a light red background, whereas ‘NECTARDUCHESSE’ fruits are colored in a pink red on 50 to 70 percent of the skin, on a cream background.

Compared to ‘NECTARDREAM’ (U.S. Plant Pat. No. 23,420) variety, which is the male parent, ‘0322E82NB’ variety blooms 13 days after. Moreover, the fruits of ‘0322E82NB’ variety ripen approximately 75 days later than the fruits of ‘NECTARDREAM’ (U.S. Plant Pat. No. 23,420). Both ‘NECTARDREAM’ (U.S. Plant Pat. No. 23,420) and ‘0322E82NB’ varieties produce fruits with a semi-sweet, sugary and aromatic flavour.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of white nectarine tree, the following was observed on trees in their third growing season (second 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” 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.

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 strong.
• Productivity: Very Productive and regular, every year. 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. 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.
