Rose plant Kortexung

A rose variety of the floribunda class is provided having an extremely long vase life for the buds and flowers, short to medium length cutting stems (less than twenty inches), high resistance to powdery mildew, and excellent flower production of long-lasting, light pink flowers.

SUMMARY OF THE INVENTION 
The present invention relates to a new and distinct variety of rose plant 
of the floribunda class, which was originated by me by crossing an unnamed 
seedling with an unnamed seedling. 
The primary objective of this breeding was to produce a new rose variety of 
the floribunda class bearing flowers in the pink color range that are 
suitable for the production of cut blooms. This objective was 
substantially achieved, along with other desirable improvements, as 
evidenced by the following unique combination of characteristics which are 
outstanding in the new variety and which distinguish it from its parents 
as well as from all other varieties of which I am aware. For example, this 
new rose variety has: 
1. Light pink buds that are very slow opening; 
2. Light pink flowers with extremely long vase life; 
3. Strong color retention; 
4. High flower production of short to medium length stems; 
5. Resistance to powdery mildew; 
6. Stiff petals. 
Asexual reproduction of this new variety by budding, as performed at Wasco, 
Calif., shows that the foregoing characteristics and distinctions come 
true to form and are established and transmitted through succeeding 
propagation.

DETAILED DESCRIPTION OF THE INVENTION 
The following is a detailed description of my new rose cultivar, which has 
been denominated "Kortexung". Color terminology is in accordance with The 
Royal Horticultural Society Colour Chart except where an ordinary 
dictionary significance for the color is apparent. 
Observations of the buds and flowers were made from specimens grown in a 
greenhouse at Irvine, Calif. in November through December. 
Flower 
The blooming habit is recurrent and continuous. The bud size is one to one 
and one-half inches when the petals start to unfurl. The bud form is long, 
pointed ovoid. The bud color when sepals first divide is near Red 49B to 
49C; when half blown, the upper side of petals is near Red 49C and the 
lower side of petals is near Red 49C. The sepals have a color near Green 
138B. The surface texture is smooth with some very fine hairs. There are 
three appendaged sepals lightly appendaged, and two unappendaged sepals 
with hairy edge. The receptacle color is near Green 138B of a funnel 
shape, small size and smooth surface. The peduncle is of medium length, 
smooth surface with some very fine hairs. Peduncle color is medium green, 
and the peduncle is stiff and erect. 
Bloom 
Bloom size is small, with an average open size of two and one-half to three 
inches, borne singly. The stems are strong, and medium to short. The form 
when first open is high center. This form is retained to the end. The 
outer petals curl back quill fashion. Under normal conditions there are 
thirty petals. The upper side of petal is near Red 49C, as is the reverse 
side of the petals. The base of petals is white semicircle near White 155B 
with the major color being near Red 49C. There are no variegations. The 
general tonality at the end of the first day shows no change in color. At 
the end of the third day, there remains no discoloration. 
The fragrance is slight. The petal texture is thick, of a deltoid shape and 
the tips are slightly recurved and becoming quilled. 
The arrangement is imbricated with no petaloids in the center. The blooms 
drop off cleanly, and last both on the plant and as a cut flower for a 
very long time. 
Reproductive Parts 
The anthers are medium size, of yellow color and arranged regularly around 
the styles. The pollen is pale yellow, and the styles and stigmas are 
white. 
Plant 
A very vigorous growth of bush form. 
Foliage 
Medium size, sparse in quantity. The new foliage is reddish, and the old 
foliage is dark green near Green 139A. Normal mid-stem leaves have five to 
seven leaflets. 
The leaflets are of an oval pointed shape, are glossy, and have a smooth 
texture with a serrated edge. The serration is single and medium in size. 
Petiole rachis is green and petiole underside is smooth with few prickles. 
Stipules are short and bearded. The foliage is resistant to mildew under 
normal growing conditions at Irvine, Calif. 
Wood 
New wood is light green, with a smooth bark. Old wood is green with a 
smooth bark. 
Prickles 
There are few prickles on main canes from the base and few on laterals from 
the main canes. The form is medium and straight. Color when young is red. 
Small Prickles 
There are no small prickles on the main stalks or on the laterals. 
Parentage 
Both the seed parent and the pollen parent were unnamed seedlings. 
Classification 
Botanical is rosa hybrid. Commercial is floribunda.
