Claims
It is claimed:
1. A new and distinct Ipomoea plant named `Kyuikukan 3` as
illustrated and described.
Description
Botanical designation: Ipomoea batatas.
Cultivar denomination: `Kyuikukan 3`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Ipomoea, botanically known as Ipomoea batatas, and hereinafter
referred to by the name `Kyuikukan 3`.
The new Ipomoea is a product of a planned breeding program
conducted by the Inventors in Miyazaki, Japan. The objective of the
breeding program is to create new compact Ipomoea cultivars with
attractive foliage shape and coloration.
The new cultivar originated from a cross-pollination made by the
Inventors in June, 2001 of the Ipomoea batatas cultivar Sweet
Garden, not patented, as the female, or seed, parent with the
Ipomoea batatas cultivar Sweet Line, not patented, as the male, or
pollen, parent. The cultivar Kyuikukan 3 was discovered and
selected by the Inventors as a single plant within the progeny of
the stated cross-pollination in a controlled environment in
Miyazaki, Japan.
Asexual reproduction of the new Ipomoea by terminal cuttings in a
controlled environment in Miyazaki, Japan since December, 2005, has
shown that the unique features of this new Ipomoea are stable and
reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Kyuikukan 3 has not been observed under all possible
environmental conditions. The phenotype may vary somewhat with
variations in environment and cultural practices such as
temperature, daylength and light intensity without, however, any
variance in genotype.
The following traits have been repeatedly observed and are
determined to be the unique characteristics of `Kyuikukan 3`. These
characteristics in combination distinguish `Kyuikukan 3` as a new
and distinct cultivar of Ipomoea: 1. Compact and outwardly trailing
growth habit. 2. Bright green-colored tri-lobed foliage.
Plants of the new Ipomoea can be compared to plants of the female
parent, the cultivar Sweet Garden. Plants of the new Ipomoea differ
from plants of the cultivar Sweet Garden in the following
characteristics: 1. Plants of the new Ipomoea have longer
internodes than plants of the cultivar Sweet Garden. 2. Plants of
the new Ipomoea and the cultivar Sweet Garden differ in leaf
coloration.
Plants of the new Ipomoea can be compared to plants of the male
parent, the cultivar Sweet Line. Plants of the new Ipomoea differ
from plants of the cultivar Sweet Line in the following
characteristics: 1. Plants of the new Ipomoea are more compact and
more trailing than plants of the cultivar Sweet Line. 2. Plants of
the new Ipomoea and the cultivar Sweet Line differ in leaf
shape.
Plants of the new Ipomoea can be compared to plants of the Ipomoea
batatas cultivar Sweet Caroline Light Green, disclosed in U.S.
Plant Pat. No. 15,028. In side-by-side comparisons conducted in
Shiga, Japan, plants of the new Ipomoea differed from plants of the
cultivar Sweet Caroline Light Green in the following
characteristics: 1. Plants of the new Ipomoea were shorter than
plants of the cultivar Sweet Caroline Light Green. 2. Plants of the
new Ipomoea had longer internodes than plants of the cultivars
Sweet Caroline Light Green. 3. Plants of the new Ipomoea had
smaller leaves and shorter petioles than plants of the cultivar
Sweet Caroline Light Green. 4. Plants of the new Ipomoea and the
cultivar Sweet Caroline Light Green differed in leaf shape and leaf
color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall
appearance of the new Ipomoea, showing the colors as true as it is
reasonably possible to obtain in colored reproductions of this
type. Colors in the photographs may differ slightly from the color
values cited in the detailed botanical description which accurately
describe the colors of the new Ipomoea.
The photograph at the top of the sheet comprises a side perspective
view of a typical plant of `Kyuikukan 3` grown in a container.
The photograph at the bottom of the sheet comprises a close-up view
of typical leaves of `Kyuikukan 3`.
DETAILED BOTANICAL DESCRIPTION
The photographs and following observations, measurements and values
describe plants grown in Shiga, Japan in a polyethylene-covered
greenhouse during the summer under conditions which closely
approximate commercial production. During the production of the
plants, day temperatures were about 28.degree. C. and night
temperatures were about 18.degree. C. Plants were about four months
old when the photographs and the description were taken. In the
detailed description, color references are made to The Royal
Horticultural Society Colour Chart, 2001 Edition, except where
general terms of ordinary dictionary significance are used.
