ABSTRACT:
Botanical classification/cultivar designation:
Begonia semperflorens
cultivar Gum Drop Rose.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of
Begonia
plant, botanically known as
Begonia semperflorens
, and hereinafter referred to by the name ‘Gum Drop Rose’.
The new
Begonia
is a product of a planned breeding program conducted by the Inventor in Fukuoka, Kyushu, Japan. The objective of the breeding program was to develop new
Begonia
cultivars with double flowers and attractive leaf and flower coloration.
The new
Begonia
originated from a cross made by the Inventor in 1995, of the
Begonia semperflorens
cultivar Double Pink, not patented, as the female, or seed parent, with the
Begonia semperflorens
cultivar Bazel, not patented, as the male, or pollen parent. The cultivar Gum Drop Rose was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Fukuoka, Kyushu, Japan.
Asexual reproduction of the new
Begonia
by cuttings taken in a controlled environment in Fukuoka, Kyushu, Japan since 1999 has shown that the unique features of this new
Begonia
are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘Gum Drop Rose’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Gum Drop Rose’. These characteristics in combination distinguish ‘Gum Drop Rose’ as a new and distinct
Begonia
cultivar:
1. Compact, upright and uniform plant habit.
2. Freely branching growth habit, dense and bushy growth habit.
3. Green-colored leaves.
4. Freely flowering habit, numerous flowers per plant.
5. Small mostly double flowers that are dark pink in color and held above and beyond the foliage.
Plants of the new
Begonia
differ from plants of the female parent, the cultivar Double Pink, in leaf and flower coloration as plants of the cultivar Double Pink have bronze-colored leaves and pink-colored flowers. Plants of the new
Begonia
differ from plants of the male parent, the cultivar Bazel, in flower form as plants of the cultivar Bazel have single flowers.
The new
Begonia
differs from plants of the
Begonia semperflorens
cultivars Gum Drop Mandarin, disclosed in U.S. Plant patent application Ser. No. 10/684,563, Gum Drop Pink, disclosed in U.S. Plant patent application Ser. No. 10/684,531, and Gum Drop Rose, disclosed in U.S. Plant patent application Ser. No. 10/684,525, primarily in flower coloration.
The new
Begonia
can also be compared to the
Begonia semperflorens
cultivar Queen Pink, not patented. However, in side-by-side comparisons conducted in Fukuoka, Kyushu, Japan, plants of the new
Begonia
differed from plants of the cultivar Queen Pink in the following characteristics:
1. Plants of the new
Begonia
had smaller leaves than plants of the cultivar Queen Pink.
2. Plants of the new
Begonia
had smaller flowers than plants of the cultivar Queen Pink.
3. Flowers of plants of the new
Begonia
were more often double than plants of the cultivar Queen Pink.
4. Flowers of plants of the new
Begonia
did not produce pollen whereas flowers of plants of the cultivar Queen Pink produced pollen.
