The present invention comprises a new and distinct cultivar of New Guinea Impatiens, referred to by the cultivar name `Tina`.
`Tina` is a product of a planned breeding program and was originated from a hybridization made by the inventor Norbert Bull in a controlled breeding program in Goennebek, Germany, in 1991. The female parent was a seedling designated No. 2 and the male parent was a seedling designated No. 3. Both parents are proprietary cultivars used in the breeding program.
`Tina` was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor in Autumn 1991 in a controlled environment in Goennebek, Germany.
The first act of vegetative or asexual reproduction of `Tina` was accomplished when cuttings were taken from the initial selection in Autumn 1992 in a controlled environment in Goennebek, by, or under the supervision of, Norbert Bull.
Horticultural examination of plants grown from cuttings of the clone initiated in Spring 1993 in Goennebek, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for `Tina` are firmly fixed and are retained through successive generations of asexual reproduction.
`Tina` has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length, without, however, any variation in genotype.
The following observations, measurements, and comparisons describe plants grown in Hillscheid, Federal Republic of Germany under greenhouse conditions which approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of `Tina`, which in combination distinguish this New Guinea Impatiens as a new and distinct cultivar:
1. White-pink flower color with purple colored eye and pink markings
2. Medium sized flowers
3. Dark green foliage with red veining
4. Small plant habit, weak growth
5. Early to medium flower response
6. Good resistance to powdery mildew
Of the many commercial cultivars known to the present inventor, the most similar in comparison to `Tina` are the commercial varieties `Melanie`, disclosed in U.S. Plant Pat. No. 8,368, and `Tahiti`, disclosed in U.S. Plant Pat. No. 8,601.
In comparison to `Melanie`, `Tina` has a more distinct purple-pink eye, a somewhat lighter main flower color, a more compact growth habit, and better lasting quality.
In comparison to `Tahiti`, the flowers of `Tina` are of similar color and size, but differently shaped, with flowers of `Tina` being slightly zygomorph in contrast to the nearly round flowers of `Tahiti`. `Tina` also has more distinct markings, darker green foliage, and a less vigorous growth habit.
The accompanying photographic drawing shows typical flower and foliage characteristics of `Tina`, with colors being as true as possible with illustrations of this type.
In the following description color references are made to The Royal Horticultural Society Colour Chart.
The color values were determined indoors from flowers taken from plants grown in Hillscheid, Federal Republic of Germany, under greenhouse conditions which approximate those generally used in commercial practice.
The description is based on plants which were planted as rooted cuttings in 10 cm pots in early March and grown at 20°C minimum temperature.
