Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Citrus reticulata Blanco Tamnaneunbong showing colors as true as is reasonably possible with colored reproduction of this type. These photos were taken in 2010 in Korea. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describes the color of the Tamnaneunbong.

(2) FIG. 1 provides multiple views of the ovaries of the fruits harvested from Tamnaneunbong and Shiranui. The four ovaries on the left of the photograph are ovaries of the fruit harvested from Shiranui while the four ovaries on the right of the photograph are ovaries of the fruit harvested from Tamnaneunbong. All are from ten years old plants.

(3) FIG. 2 provides multiple views of typical fruits harvested from ten years old Tamnaneunbong plants. Top, bottom and side views of the whole, unpeeled fruit is shown as well as two cross-sectional views of the inside of the fruit.

(4) FIG. 3 provides multiple views of typical fruits harvested from ten years old Shiranui plants. Top, bottom and side views of the whole, unpeeled fruit is shown as well as two cross-sectional views of the inside of the fruit

(5) FIG. 4 illustrates in full color typical foliage and fruits of Tamnaneunbong on the ten years old tree.

(6) FIG. 5 illustrates in full color typical foliage and fruits of Shiranui on the ten years old tree.

DETAILED BOTANICAL DESCRIPTION

(7) In the following description of the new cultivar Tamnaneunbong as taken from tests carried from 2007 to 2010. The characteristics of the overall Tamnaneunbong plant include strong tree vigor, erect-type tree form, fruit shape which is oblate, orange pericarp color, orange flesh color, strong fragrance and moderate oil glands. The following observations and measurements describe Tamnaneunbong plants grown in Korea.

(8) The Colour Chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, 2007, Fifth edition, except where general color terms of ordinary significance are used.

Other fruit features.Tamnaneunbong is intermediate resistant to citrus scab disease and citrus canker, but susceptible to melanose. For the very early mature stage, Tamnaneunbong should be protected when cultured. Since the fruit would be matured in the cold season, the cold season may reduce the quality of the fruit if the fruit is planted in an open field. Therefore, Tamnaneunbong needs to be planted under a protected environment. Pruning on Tamnaneunbong is the same as Shiranui. Fruit and plant are damaged when the temperature is below 7 C.
