Claims
I claim:
1. A new and distinct variety of rose plant of the hybrid tea
class, substantially as herein shown and described, characterized
particularly by its clear white, well-formed flowers; very strong
fragrance; long vase life; strong, upright growth; dark green,
healthy foliage; and ability to root easily and also to grow
vigorously with the aid of an understock.
Description
Genus and species: Rosa hybrida.
Variety denomination: `JACsegra`.
ORIGIN OF THE INVENTION
The present invention relates to a new and distinct variety of a
hybrid tea rose plant named `JACsegra` which was originated by me
by crossing the variety `HILaroma` (Secret) (U.S. Plant Pat. No.
8,494) with the variety `JACsee` (Fragrant Lace) (U.S. Plant Pat.
No. 11,138).
BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce a new hybrid
tea rose variety having the strong fragrance and wonderful flower
form of the female parent combined with the strong fragrance and
strong disease resistant foliage of the male parent.
BRIEF SUMMARY OF THE INVENTION
The objective was substantially achieved, along with other
desirable improvements, as evidenced by the following unique
combination of characteristics that are outstanding in the new
variety and that distinguish it from its parents, as well as from
all other varieties of which I am aware: 1. Clear white,
well-formed flowers. 2. Very strong citrus fragrance. 3. Long vase
life. 4. Strong, upright growth. 5. Dark green, healthy foliage. 6.
Ability to root easily and also to grow vigorously with the aid of
an understock.
Asexual reproduction of this new variety by cuttings, as performed
at Wasco and Somis, Calif., shows that the foregoing and all other
characteristics and distinctions come true to form and are
established and transmitted through succeeding propagations.
Comparison with Parents
`JACsegra` differs from the female parent in flower color (pink
versus white) and in flower size (12-13 cm versus 15 cm for
`JACsegra`). `JACsegra` differs from the male parent in flower
color (light pink versus white) and in open flower form (the center
of the flower has many petals and petaloids for `JACsee` versus
imbricated for `JACsegra`).
Comparison with Similar Variety
`JACsegra` differs from other white hybrid teas by its powerful
fragrance and the strong resistance to fungal diseases found in
`JACsegra`. The closest hybrid teas are `JAColite` (expired U.S.
Plant Pat. No. 4,167) and `MAClanoflon` (believed unpatented).
BRIEF DESCRIPTION OF THE ILLUSTRATION
The accompanying illustration shows typical specimens of the
vegetative growth and flowers of this new variety in different
stages of development, depicted in color as nearly true as it is
reasonably possible to make the same in a color illustration of
this character.
DETAILED BOTANICAL DESCRIPTION
