Description

Latin name of the genus and species of the plant claimed: Malus domestica Borkh.
Variety denomination: ‘REGALNAT’.
This application claims priority of Community plant variety right No. 2019/3252 filed on Nov. 29, 2019 (Nov. 29, 2019) which is hereby incorporated by reference in its entirety.
BACKGROUND OF THE NEW VARIETY 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, France.
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 ‘REGALNAT’. This tree produces fruits with a long shelf life without alteration after harvesting, very good eating quality with a white flesh for fresh market in September or October in the Pyrénées Orientales department, France. Contrast is made to ‘REGALYOU’ apple tree variety (U.S. Plant Pat. No. 25,827) for reliable description. Contrast is also made to the parent varieties of ‘REGALNAT’, that are ‘ARIANE 6407RT’ (female or seed parent—non patented) and ‘SELECTION INRA 6062RT’ (male or pollen parent—non patented).
‘REGALNAT’ 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. ‘REGALNAT’ apple tree originated in a cultivated area of the South of France, in the Pyrénées-Orientales department 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 700 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 ‘REGALNAT’ variety results from a pollinated cross between the ‘ARIANE 6407 RT’ apple tree (non patented) which was used as a seed parent and the ‘SELECTION INRA 6062RT’ apple tree (non patented) which was used as the pollen parent.
The ‘REGALNAT’ 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 plants 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 ‘REGALNAT’ produces fruits of large size, firm and crunchy, and with dark red color. The blooming period is medium for the variety, namely in the middle of April. The maturity period is considered late, usually at the end of September or early in 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. Colour 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 semi-sweet apple are a large fruit size with a color of skin considered dark red. The fruit flesh is cream. The fruit is firm.
The time of beginning of flowering is medium whereas the time of beginning of fruit ripening is considered late.
In comparison with the ‘REGALYOU’ apple tree variety (U.S. Plant Pat. No. 25,827), ‘REGALNAT’ apple tree ripens earlier during the season. Namely, the fruits of ‘REGALNAT’ apple tree variety ripen 5 to 7 days before the fruits of ‘REGALYOU’ apple tree variety. Also, the blooming periods of ‘REGALNAT’ is also different from the blooming period of ‘REGALYOU’, as the flowers of ‘REGALNAT’ usually bloom a few days later than the flowers of ‘REGALYOU’. Fruits are also different in regards of fruit shape: ‘REGALNAT’ fruits are considered to be round and very regular whereas the shape of ‘REGALYOU’ fruits is considered to be obloid, round to slightly flatten. The skin color of ‘REGALYOU’ fruits is considered bright red on approximately 70-80% of the fruit skin, whereas the fruit skin for ‘REGALNAT’ is colored with a very luminous red covering approximately 90 to 100% of the fruit skin surface, on a washed orange red background.
The flavor of the ‘REGALNAT’ fruit flesh is considered to be perfectly balanced between sugar and acidity, whereas the fruits of ‘REGALYOU’ present a lower acidity, with a semi-sweet taste.
Compared to its seed parent, which is the ‘ARIANE 6407RT’ apple variety (non patented), the fruits of the new variety ‘REGALNAT’ ripen approximately one week earlier. The fruits produced by the ‘REGALNAT’ variety are bigger than those produced by its seed parent (respectively between 75.0 and 80.0 millimeters, vs. between 65.0 and 75.0 millimeters). The skin color of ‘ARIANE 6407RT’ fruits is considered red on approximately 75% of the fruit skin, on a washed red background, whereas the fruit skin for ‘REGALNAT’ is colored with a very luminous red covering approximately 90 to 100% of the fruit skin surface, on a washed orange red background.
The pollen parent of the new variety, which is the ‘SELECTION INRA 6062RT’ apple variety (non patented), considering the observations we have made on our production site, ripens approximately during the second half of September, usually from September 13th, until September 26th. The REGALNAT variety ripens approximately at the same time in comparison with its pollen parent. ‘REGALNAT’ fruits are considered to be round and very regular whereas the shape of ‘SELECTION INRA 6062RT’ fruits is considered to be round and flattened. The skin color of ‘SELECTION INRA 6062RT’ fruits is considered red on approximately 80% of the fruit skin, whereas the fruit skin for ‘REGALNAT’ is colored with a very luminous red covering approximately 90 to 100% of the fruit skin surface, on a washed orange red background. The fruits of the ‘SELECTION INRA 6062RT’ have a fruit stem considered long, whereas the length of the fruit stem for the ‘REGALNAT’ variety fruits is considered medium to long.
The ‘REGALYOU’ (U.S. Plant Pat. No. 25,827) apple tree variety is considered as good pollinators for the new variety ‘REGALNAT’.
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 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 cultivar. The rootstock was a ‘M9EMLA’ (non-patented) tree. All major color code designations are by reference to The R.H.S. Color Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.
