Lily plant named Berlin

Abstract

A lily plant named Berlin, characterized by its light pink main flower color, cherry red streaking along the midvein of each tepal, red-purple spot markings, very upright flower position and its floriferous habit.

Description

The present invention comprises a new and distinct cultivar of lily, botanically known as Lilium, known commercially as Lilium oriental hybrid, and hereinafter referred to by the cultivar name Berlin. The parents were oriental varieties belonging to division VII(b) described in "Classification of Lily Cultivars into Divisions" published by Victoria Mathews, The Royal Botanic Gardens, Kew (1989).

The new cultivar is a product of a planned breeding program which had the primary objective of creating new lily cultivars with good forcing characteristics so as to produce many flowers at minimal bulb size.

The new cultivar was originated from a hybridization made by the inventor in a controlled breeding program in Rijnsburg, The Netherlands in 1981. The female parent was the cultivar Stargazer. The male parent was an unnamed seedling.

The new cultivar was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor in July 1981 in a controlled environment in Rijnsburg, The Netherlands.

The first act of asexual reproduction of the new cultivar was accomplished by the inventor when scales were taken from the initial selection in 1985 in a controlled environment in Rijnsburg, The Netherlands.

Horticultural examination of selected units has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and are retained through successive generations of asexual reproduction.

The new cultivar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, and day length, without, however, varying in the genotype. The following observations, measurements and comparisons describe plants grown in Wageningen and Rijnsburg, The Netherlands 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 Berlin which in combination distinguish this lily as a new and distinct cultivar.

1. A distinctive light pink main flower color;

2. Streaking or striping which is cherry red in color along each midvein, to near the tip of the tepal;

3. Many red-purple spot markings on each tepal;

4. Very upright flower position;

5. Very floriferous habit.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new cultivar is Stargazer. In comparison to Stargazer, Berlin has more flowers for the same bulb size, lighter pink flower color with red striping in the center of the tepal, and longer stems. Berlin generally produces 1 to 2 more flowers than Stargazer at the same bulb size. Berlin bulbs measuring approximately 16 centimeters produce 5 to 7 flowers. When flowering is forced under natural light, Berlin produces an inflorescence approximately 9 days earlier than Stargazer, grown under the same conditions. Berlin is fertile.

The accompanying color photographic drawing shows typical flower characteristics of the new cultivar, with colors being as true as possible with illustrations of this type. The photograph comprises a front perspective view showing several flowers open and numerous buds in various stages.

In the following description, color references are made to The Royal Horticultural Society (R.H.S.) Colour Chart. The color values were determined at Wageningen in 1988-1989 and at Rijnsburg in July 1991.
