Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘BOTA 2802’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hybrid Tea Rose plant, botanically known as Rosa hybrida, and hereinafter referred to by the cultivar name BOTA 2802.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Klazienaveen, The Netherlands. The objective of the breeding program was to develop new cut Rose cultivars with a high yield of cut flowering stems, large flower buds and flowers, attractive flower color, long and strong stems, dark green leaves and good postproduction longevity.

The new cultivar originated from a cross-pollination made by the Inventor on Feb. 15, 2002 of the Rosa hybrida cultivar Iceberg, not patented, as the female, or seed, parent and the Rosa hybrida cultivar Passion, not patented, as the male, or pollen, parent. The cultivar BOTA 2802 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Klazienaveen, The Netherlands.

Asexual reproduction of the new cultivar by cuttings at Klazienaveen, The Netherlands, since June, 2002, has shown that the unique features of the new cultivar are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BOTA 2802’. These characteristics in combination distinguish the new Hybrid Tea Rose as a new and distinct cultivar:

    • 1. Strong and dark green-colored leaves.
    • 2. Vigorous growth habit.
    • 3. Long and strong flowering stems without thorns.
    • 4. Pink, white and green-colored flowers with numerous petals.
    • 5. High yield of cut flowering stems.
    • 6. Good postproduction longevity.
    • 7. Not susceptible to Powdery Mildew.

Plants of the new Hybrid Tea Rose can be compared to plants of the female parent, the cultivar Iceberg. In side-by-side comparisons conducted in Klazienaveen, The Netherlands, plants of the new Hybrid Tea Rose differed from plants of the cultivar Iceberg in the following characteristics:

    • 1. Plants of the new Hybrid Tea Rose had longer flowering stems than plants of the cultivar Iceberg.
    • 2. Plants of the new Hybrid Tea Rose produced fewer flowering stems than plants of the cultivar Iceberg.
    • 3. Plants of the new Hybrid Tea Rose had broader flower buds than plants of the cultivar Iceberg.
    • 4. Plants of the new Hybrid Tea Rose had more petals per flower than plants of the cultivar Iceberg.
    • 5. Plants of the new Hybrid Tea Rose and the cultivar Iceberg differed in flower color as plants of the cultivar Iceberg had white-colored flowers.
    • 6. Plants of the new Hybrid Tea Rose had better postproduction longevity than plants of the cultivar Iceberg.

Plants of the new Hybrid Tea Rose can be compared to plants of the male parent, the cultivar Passion. In side-by-side comparisons conducted in Klazienaveen, The Netherlands, plants of the new Hybrid Tea Rose differed from plants of the cultivar Passion in the following characteristics:

    • 1. Plants of the new Hybrid Tea Rose had longer flowering stems than plants of the cultivar Passion.
    • 2. Plants of the new Hybrid Tea Rose produced fewer flowering stems than plants of the cultivar Passion.
    • 3. Plants of the new Hybrid Tea Rose had larger flower buds than plants of the cultivar Passion.
    • 4. Plants of the new Hybrid Tea Rose and the cultivar Passion differed in flower color as plants of the cultivar Passion had red-colored flowers.

Plants of the new Hybrid Tea Rose can be compared to plants of the Rose cultivar Bella Vita, not patented. In side-by-side comparisons conducted in Klazienaveen, The Netherlands, plants of the new Hybrid Tea Rose differed from plants of the cultivar Bella Vita in the following characteristics:

    • 1. Plants of the new Hybrid Tea Rose produced more flowering stems than plants of the cultivar Bella Vita.
    • 2. Plants of the new Hybrid Tea Rose did not have any thorns whereas plants of the cultivar Bella Vita had thorns.
    • 3. Plants of the new Hybrid Tea Rose had larger flower buds than plants of the cultivar Bella Vita.
    • 4. Plants of the new Hybrid Tea Rose and the cultivar Bella Vita differed in flower color as plants of the cultivar Bella Vita had lighter pink-colored flowers and did not have green coloration on the outer petals.
    • 5. Plants of the new Hybrid Tea Rose had better postproduction longevity than plants of the cultivar Bella Vita.
    • 6. Plants of the new Hybrid Tea Rose were not susceptible to Powdery Mildew whereas plants of the cultivar Bella Vita were susceptible to Powdery Mildew.

Plants of the new Hybrid Tea Rose can be compared to plants of Rose cultivar Barcelona, not patented. In side-by-side comparisons conducted in Klazienaveen, The Netherlands, plants of the new Hybrid Tea Rose differed from plants of the cultivar Barcelona in the following characteristics:

    • 1. Plants of the new Hybrid Tea Rose had longer flowering stems than plants of the cultivar Barcelona.
    • 2. Plants of the new Hybrid Tea Rose had longer stipules than plants of the cultivar Barcelona.
    • 3. Plants of the new Hybrid Tea Rose had larger flower buds than plants of the cultivar Barcelona.
    • 4. Plants of the new Hybrid Tea Rose and the cultivar Barcelona differed in flower color as plants of the cultivar Barcelona had darker pink-colored flowers.
