Definitions
- KEDEM mandarin citrus Citrus reticulata hybrid
- the present invention relates to a new and distinct variety of mandarin Citrus reticulata hybrid developed by inventors Aliza Vardi, Pinchas Spiegel-Roy, Avraham Elchanati, Ahuva Frydman-Shani and Hana Neumann in Bet Dagan, Israel from a selection of plants grown from irradiated buds of the cultivar ‘Rishon’.
- the objective in breeding the present new variety, known by the designate ‘KEDEM’ was to induce seedless varieties through mutation breeding in easy peeling varieties.
- ‘Rishon’ U.S. Plant Pat. No. 8,377
- ‘Rishon’ was the result of a controlled pollination cross, made at the Volcani Center, Bet Dagan, Israel, in 1978 between ‘Temple’ (Citrus temple Hort. ex Y.
- ‘Michal’ is a cultivar of Israeli origin believed to be a natural hybrid between two Citrus reticulata ‘Blanco’ cultivars.
- Troyer nucellar rootstocks were bud grafted with the individual buds of irradiated ‘Rishon’ bud wood and labeled mV 1 . Six to nine months after grafting the irradiated budwood, individual buds from the mV 1 plants were re-grafted on Troyer nucellar rootstocks to establish about 300 mV 2 plants.
- a selection designated 13/5/82 had medium size orange color fruit, was easy to peel and had few seeds.
- the selection was distinguished from ‘Rishon’ as having 0-5 seeds per fruit as compared with 5-11 seeds for ‘Rishon’ and having a lower pollen fertility of 72% compared with 95% for ‘Rishon’ when pollen grains were stained with acetocarmine.
- KEDEM is a new variety of mandarin citrus that has a fruit with few seeds and flowers having anthers bearing pollen with low fertility compared to the parent ‘Rishon’.
- Table 1 shows some of the characteristics of ‘KEDEM’ compared to the parent ‘Rishon’.
- the tree shape is similar to that of ‘Rishon’.
- the tree is vigorous and has small thorns in the leafy part of branches, especially in the lower portion and on the lower part of fruit bearing branches.
- Main branches have an upright attitude and young shoots have no anthocyanin coloration at the tip.
- the fruits of selection ‘KEDEM’ develop the exterior orange color very early in the season, beginning in October, while at the same time the exterior color of the fruits of ‘Rishon’ are green-yellow.
- the bearing of the tree is regular and the productivity is good, about the same as for ‘Rishon’.
- the canopy is moderately dense.
- the bark of the young shoots is initially smooth and green gradually turning into a smooth yellow-green.
- the leaves of ‘KEDEM’ are similar to those of ‘Rishon’. They are lanceolate and sharp pointed, small to medium in size. Leaf blade is firm, without undulation and straight concave in cross section. Petioles are without wings or have rudimentary wings.
- the fruit has few seeds, about 0-5, even when optimal pollination conditions are employed. This compares with about 5-9 seeds per fruit in ‘Rishon’. Except for color development, the fruit characteristics of ‘KEDEM’ are in the range of the parent cv. ‘Rishon’.
- the fruit shape is oblate and small to medium sized. When 50 fruits were measured, the fruit had an average weight 79 grams, an average height of 51 mm, and an average diameter of 56.5 mm. The fruit occasionally has a short necked and a depressed distal end. The fruit surface is usually smooth with an orange color, RHS 25A on The Royal Horticultural Society of London Colour Chart, and bears an average number of conspicuous rind oil glands. Fruit ripening does not differ from outside of the canopy to the inside, but the fruit color of the outside canopy is a little brighter compared to the fruit color of the inside canopy. There is no persistence of the style and the areola is not completely developed. A navel is absent or very rare. The rind is thin and easy to peel.
- the color of the albedo is white and the flesh is yellow-orange in color.
- the fruit contains 9-11 segments and is very juicy.
- the seeds are small, smooth and polyembryonic as are the seeds of the parent ‘Rishon’.
- the external color of the seeds is ivory when fresh and yellowish when dry.
- the internal seed coat is white and the cotyledons are greenish. Polyembryonic seeds are present.
- the seed size, shape and texture are similar to that of the parent ‘Rishon’.
- the fruit reaches maturity early or very early in the season as does ‘Rishon’, which in Israel is late September to October.
- the ripening of the fruit on the tree and within the fruit is uniform. Fruit remaining on the tree does not regreen. If there is a heavy crop and the fruits are not picked the following season, the tree may produce less fruit (becomes alternate bearing). Pre-harvest drop of both developed and undeveloped fruit is similar to that of the parent cv. ‘Rishon’.
- the photographs show the whole tree and canopy shape (Sheet 1 ) as well as the exterior of the new fruit (Sheet 2 ) illustrating the exterior of ‘KEDEM’ as well as transversal midsection in a plane substantially perpendicular to the axis.
- Trunk diameter 7 cm at 20 cm above the ground.
- Anther color Yellow-orange RHS 20A.
- Rind. Thin and easy to peel.
- Cotyledons Green RHS 142C.
- Embryony Polyembryonic (more than one embryo per seed).
- the tree and fruit described herein may vary in slight detail due to climate and/or soil conditions under which the variety is grown.
