Abstract
Disclosed is a citrus tree having a moderate spreading vigor, and bearing medium size and compressed round shaped fruit with a deep orange skin color and a low acidity. This new and distinct variety of citrus tree is an early maturing citrus cultivar, is fairly resistant to diseases, was bred by a crossing of "Seike navel" (the seed parent) and "Clementine" (the pollen parent), bears good quality fruit, and is an excellent citrus cultivar.
Description
The present invention relates to a new and distinct variety of citrus tree, and more particularly, to a citrus tree having a strong resistance to diseases compared with Navel Orange and a low acidity, and bearing an excellent table fruit.
In Japan, the variety "Navel Orange", which is an early maturing cultivar, has been cultured, to provide a table fruit, but the fruit of this variety may have a high acidity at the end of year marketing season and a weak resistance to diseases, and there is a continuing need for a citrus variety having a higher quality as a table fruit than the conventional variety.
The efforts by the present breeders have been aimed at obtaining a new variety that can replace "Navel Orange". Namely, the object of the present invention is to provide a new and distinct variety of citrus tree bearing a fruit of high quuality, having a strong resistance to diseases annd a low acidity, having no seeds, and ripening in early season.
This new variety of citrus tree was a cross-seedling obtained from a crossing of "Seike navel" (♀) (the seed parent) and "Clementine" (♂) (the pollen parent) at the Kuchinotsu Branch, Fruit Tree Research Station (Otsu-870, Kuchinotsu-cho, Minamitakaki-gun, Nagasaki-ken, Japan).
Specially, this crossing was carried out at the Kuchinotsu Branch in 1973, and in 1974 the resulting seeds were sown in a glass house to grow seedlings. The scion obtained from the seedlings were top-worked to a Citrus unshiu Marc. for interstock, to shorten the juvenile phase, in September, 1974, and the tree thus-- grown bore fruit for the first time in 1978; and the quality of the fruit met the above-mentioned purpose. Accordingly, the tree was selected as the first selection based on the results of a few years' research, and was subjected to local adaptability tests, beginning in 1987. These tests were conducted at 21 of the experimental stations in the main Japanese citrus-growing regions such as Nagasaki-ken, and Wakayama-ken, etc., under the strain number "Kuchinotsu 13".
As a result, it was found that the trees had stable characteristics, and can be disyinguished from other similar varieties. The breeders denominated the afore-said citrus variety of tree in accordance with this invention as "Ariake". The genus of the cultivate is "Citrus", and the group of the same is "Tangor (hybrid of mandarin and sweet orange)".
The afore-said variety "Seike navel" is the seed parent and is an early maturing citrus that is used as a body to breed seedless variety, and bears fruit with a high productivity and a high quality. Another variety "Clementine" bears fruit with a low acidity, a high Brix, and a relatively strong resistance to diseases.
The breeders asexually reproduced this new and distinct variety of citrus tree "Ariake", by grafting, at the Kuchinotsu Branch, and at other Branches of the Fruit Tree Research Station, Ministry of Agriculture, Forestry and Fisheries, Japan, and confirmed the homogeneity and stability of "Ariake" according to this invention.
An application for this new variety of citrus tree "Ariake" under the Seeds and Seedlings Law of Japan was filed on Apr. 30, 1992, and was registered on Jul. 17, 1992 under the registration number 4.
This new variety of citrus tree has a moderate vigor with a growth habit of spreading, and an internode with a moderate thickness and length. There are few thorns on the tree, and the shape of the leaf of the tree is fusiform and similar in appearance to "Seike navel". The size of the leaf is smaller than that of "Clementine", and is slightly larger than that of "Seike navel". The flower is raceme, and is smaller than that of "Seike navel", but is larger than that of "Clementine". The color of the flower is white, and it has 4.7 petals. The fertility of the pollen is low, and the female sterility is very high, and the fruit is almost seedless. The bearing age and fruit set percentage of the tree are medium.
The fruit generally has a weight of about 154g; this is bigger than that of "Clementine", but is smaller than that of "Seike navel". The shape of the fruit is round and the skin of the fruit has a deeper orange-color, similar to "Seike navel", and the optimum color of the fruit is reached in early December. The surface of the fruit is smooth and the thickness of the skin is 3.9 mm, and the peeling characteristic is slightly inferior to that of "Clementine". The flesh is deep orange colored, and similar to "Clementine". The texture of the flesh is soft and juicy, and similar to "Clementine". Further, the flesh has a high sweetness, a low acidity, and moderate flavor. The segments of the flesh are thin. The embryo is white colored, and is monoembryo.
Regarding damage by diseases, the tree of this invention has a strong resistance to scab, and a normal or slightly strong resistance to bacterial canker. Further, the tree of this variety has a fairly and moderately resistance to cold.
The color values presented herein are taken from the Inter-Society Color Council-National Bureau of Standards (ISCC-NBC).
