Rose Red Intuition

Very recognizable rose which abundantly and nearly continuously produces attractive very double flowers of a clear red colour striped with darker red. Forms attractive plants with a bushy growth habit, and dense dark green, semi-glossy vegetation, and is well suited both for growing in a gardens and in a greenhouses for production of cut flowers. The flowers exhibit a good vase life or will last on a plant for a long time despite rains or heat.

DESCRIPTION OF THE VARIETY
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart-1991).

FLOWERING
The variety has very good, repeated flowering, blooms abundantly and nearly continuously. In a greenhouse conditions the variety is able to produce flowers year-round.

Flower bud:
The flower buds have ovate shape in longitudinal section just before the opening of the sepals. Before the calyx breaks the bud has length of about 2.8 to 3.1 cm, with an average length of approximately 3 cm. The colour of the bud as calyx breaks is dark red (Group 45B) striped with dark purple red (Group 53A). The length of the bud after the calyx breaks is about 3.8 to 4.5 cm, with an average length of approximately 4 cm. The colour after the calyx breaks is dark red (Group 45B) striped with dark purple red (Group 53A).

Number of flower buds is generally one per stem when grown under a greenhouse conditions; however, sometimes during forced culture an axillary eye or eyes below the flower develop to form 1 or 2 flowers.

The peduncle is erect, stiff, has medium green colour (Group 144A) with some small hairs. The length of the peduncle is about 8.5 – 11.5 cm, with an average length of 10 cm.

There are 2 sepals commonly possess no extensions, and 3 sepals commonly possess medium to strong extensions. The extensions are denticulate and commonly are long to very long. The sepal length is about 5 – 7 cm. The colour of the sepals is medium brown green (Group 147B) on the upper surface and dark brown green (Group 146B) on the under surface.

Bloom:
The flowers of ‘Red Intuition’ are medium to large, the diameter of the open flower is approximately 10 to 12 cm, and approximately 11 cm on average, with a standard deviation of 0.5 cm. The flowers have high-centered, an irregularly rounded shape when viewed from above. They are very double, with flattened convex at the upper part when viewed from the side and flattened convex to convex at the lower part when viewed from the side.

They last of a plant long – about 7 to 10 days under normal growing conditions. When cut and placed in a vase, the flowers commonly last approximately 5 to 6 days.

Petals:
The number of petals on a flower is about 31 to 39, with an average of approximately 36. The length of the petals on the second row from the outside is about 5.5 - 6.5 cm with a mean of approximately 5.9 cm, and a standard deviation of 0.4 mm; the width is approximately 5.5 – 6.9 cm with a mean of approximately 5.3 cm, and a standard deviation of 6 mm. The shape of the petals of the first row is commonly exhibits a broad ovate configuration, the undulation of the petal margins is average, and the reflexing of the margins is average.

The following description of a colour of a nearly fully open flower was made while observing a rose which had been undergoing opening for three days:

The petal colour in the middle zone: on the inner surface is medium red (Group 50A) striped with dark purple red (Group 53A); and on the outer surface is red pink (Group 53C and 53D) with darker striping of dark red (Group 53B) or red pink (Group 53C).

The colour of the petals on the marginal zone on the inner surface is medium red (Group 50A) striped with dark purple red (Group 53A), and on the outer surface is red pink (Group 53C and 53D) with darker striping of dark red (Group 53B) and red pink (Group 53C).

The basal spot on the petals is small in size and can be absent when the plant is grown outdoors. The color of the spot in the inner side is medium yellow (Group 9C) .and on the outer side is light yellow (Group 1D).

Petals drop off cleanly when the flower fades.

ORIGIN OF THE VARIETY
The rose variety ‘Delstriro’ / ‘Red Intuition’ was discovered in a greenhouse at Hyères, France, during 1999 and is a spontaneous mutation of unknown causation of the ‘Delego’ / ‘Belle Rouge’, a Hybrid Tea rose variety from Delbard, 1996. Had this variety not been discovered and preserved it would have been lost to mankind.

SUMMARY OF THE VARIETY
The rose variety ‘Delstriro’ / ‘Red Intuition’ exhibits the following combination of characteristics:

1. Forms green mature wood, displays a bushy growth habit, and forms attractive long lasting clear red striped with darker red double flowers, and;

2. Forms semi-vigorous to vigorous vegetation, produces flowers in abundance, exhibits the ability readily to be forced, and is resistant to diseases.

3. Produces relatively straight stems, rigid and substantially straight peduncles, has excellent ability to be forced under greenhouse growing conditions, and a good vase life for the distinctive clear red striped with dark red blossoms.

The rose variety ‘Delstriro’ / ‘Red Intuition’ underwent an asexual propagation and can be readily reproduced by conventional routes, such as budding (i.e., eye grafting), the rooting of cuttings and tissue culture. This asexual reproduction by budding as performed at Hyéres, France, has demonstrated that the characteristics of the new variety are stable and are strictly transmissible from one generation to another.

COMPARISON WITH PARENTS
The ‘Delstriro’ / ‘Red Intuition’ can be easily distinguished from other varieties as well as from the parent variety ‘Delego’ / ‘Belle Rouge’ by the following characteristics:

While the parent ‘Delego’ / ‘Belle Rouge’ rose variety display dark red flowers without the stripes, the flowers of ‘Delstriro’ / ‘Red Intuition’ have striped red flowers.
