Description

Latin name of the genus and species of the plant claimed: Malus domestica Borkh.

Variety denomination: ‘REGALYOU’.

This application claims priority of Community plant variety right No. 2012/0751 filed on Apr. 2, 2012 (Apr. 2, 2012) which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE NEW VARIETY

1. Field of the Invention

In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and reproduction of orchard trees, among which apple, peaches, nectarines, apricots, and cherries are exemplary. It was against this background of our activities that the present variety of apple tree was originated and reproduced by us in our experimental orchard located near Elne, Pyrénées Orientales, an administrative department of France.

2. Origin of the Variety

The present invention relates to a new a distinct variety of apple tree Malus domestica Borkh. which has been given the variety denomination ‘REGALYOU’. This tree produces fruits with a long shelf life without alteration after harvesting, very good eating quality with a yellow flesh for fresh market in October in the Pyrénées Orientales department, France. Contrast is made to its parents ‘RAKURAKU’ apple tree (non patented) and to ‘ARIANE 6407 RT’ apple tree (non patented) for reliable description. ‘REGALYOU’ is a promising candidate for commercial success in that it produces very attractive fruits having a long shelf life.

The present new variety of apple tree (Malus domestica Borkh.) was developed by us in our experimental orchard located in France. ‘REGALYOU’ apple tree originated in a cultivated area of the South of France, in the Pyrénées-Orientales, an administrative department of France, where it was also tested. This zone also called Roussillon is subject to a Mediterranean climate. The winter is generally sweet and the summer is hot and dry. The total amount of cold hours lower than 7° C. (Celsius) varies from 600 hours to 1200 hours. The total amount of sunshine hours is an average of 2400 hours to 2800 hours per year. The prevailing wind is called “Tramontane”: it dries the air and clear the sky from cloud but its intensity can be strong and affect the harvest, fruits 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 and the summer is dry with a few thunderstorms.

The ‘REGALYOU’ variety results from a pollinated cross between the ‘RAKURAKU’ apple tree (non patented) which was used as a seed parent and the ‘ARIANE 6407 RT’ apple tree (non patented) which was used as the pollen parent.

‘REGALYOU’ variety was provisionally designated, tested and genetically identified by a genetic profile under number 03.29E.43POM-ASF0720 and was registered at the Official Catalogue of the Agricultural Ministry of the French Republic on Nov. 27, 2011, under the number 4049385.

The ‘REGALYOU’ variety was obtained by hybridizing and propagated by grafting on a ‘M9EMLA’ (non-patented) rootstock trees. It has been determined to have unique tree and fruits characteristics making it worthy for commercial fresh fruits production. There are no known effects of the standard rootstock tree set forth above on the scion cultivar. Asexually propagated trees remained true to the original tree and all characteristics of the tree and the fruit were transmitted. The plant was asexually reproduced 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 NEW VARIETY

The new variety ‘REGALYOU’ produces fruits of large size, very firm and juicy, and with a luminous red color. The blooming period is medium for the variety, namely in the beginning of April. The maturity period is late or very late, generally during the first week of October in the South of France. However, it was observed that its early date of blooming and maturity seems to be highly dependant on climatic conditions.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following is a detailed botanical description of the new variety of apple tree, its flowers, foliage and fruit, as based on observations of specimens grown near Elne, South of France, with color in accordance with The R.H.S. Color Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

The trees, flowers and fruits may vary in slight detail due to variations in soil type, cultural practices and climatic conditions.

The main characteristics of this new variety of sweet apple are a large fruit size with a color of skin considered red. The fruit flesh is yellow. The fruit is very firm.

The time of beginning of flowering is medium whereas the time of beginning of fruit ripening is considered late or very late.

In comparison to ‘FUJI’ apple tree variety (non-patented'), ‘REGALYOU’ apple tree blooms 3 days earlier and ripens approximately at the same time as ‘FUJI’. The skin coloration of ‘FUJI’ variety is considered pink red covering 50 to 70% of skin whereas the skin coloration of ‘REGALYOU’ is luminous red on 80 to 90% of the fruit skin. The tree's ramification of ‘REGALYOU’ is denser than ramification of ‘FUJI’ apple tree. Flavor of ‘REGALYOU’ fruits is considered semi-sweet whereas ‘FUJI’ fruits show a sweet taste. Finally, ‘REGALYOU’ variety produces fruits regularly, without alternation, contrary to ‘FUJI’ variety, which may show an alternation in fruits production.

The female parent of the new variety, which is denominated ‘RAKURAKU’ (non-patented) is a striated mutant of the ‘FUJI’ variety. In comparison with the apple tree ‘RAKURAKU’, the present variety ‘REGALYOU’ have a tree's ramification denser compared to ramification of ‘RAKURAKU’, which is considered very weak or even insufficient. The fruits productivity of ‘REGALYOU’ is higher than ‘RAKURAKU’ productivity, considered medium because of its susceptibility to alternate production. Fruits of ‘RAKURAKU’ are round with few bumps whereas ‘REGALYOU’ fruits are regular-shaped. The color of ‘REGALYOU’ fruits skin is also more interesting, with a luminous red that covers 80% to 90% of the fruit skin on a wash red orange background; in comparison, fruit skin of ‘RAKURAKU’ is pink red on a greenish yellow background. Fruits flesh of ‘REGALYOU’ apple tree is not fibrous, contrary to ‘RAKURAKU’ fruits flesh, and ‘REGALYOU’ taste is slightly acid and aromatic.

The male parent of the new variety ‘ARIANE 6407 RT’ (non-patented) was obtained by INRA® and is resistant to common species of the fungus named Venturia inaequalis. ‘REGALYOU’ tree's ramification is higher than ‘ARIANE 6407 RT’ tree's ramification, which is considered medium or insufficient. The level of production of the new variety is similar to those of ‘ARIANE 6407 RT’ and considered regular without susceptibility to alternate production. ‘REGALYOU’ fruits don't include lenticels, in comparison with ‘ARIANE 6407 RT’ fruits. Moreover, ‘REGALYOU’ fruits are larger than ‘ARIANE 6407 RT’ fruits.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of apple tree, the following has been observed on trees on their third growing season (second year of production) under the ecological conditions prevailing at the orchards located near the town of Elne, Pyrénées-Orientales, an administrative department of France.
