USPP8322P - Lily plant named Marco Polo - Google Patents

Abstract

A new and distinct cultivar of lily plant named Marco Polo, characterized by its large, generally upright flowers, the base color of which is white infused with light pink, with pink being more prevalent near the distal end and along the midvein, vigorous growth habit, tall plant height, and its contrasting reddish brown pollen.

Description

The present invention comprises a new and distinct cultivar of lily, botanically known as Lilium, commercially known as Lilium oriental hybrid, and hereinafter referred to by the cultivar name Marco Polo. 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 objectives of creating new lily cultivars with a new soft pink color, larger semi-upright flowers, and having other desirable traits for use in cut flower production.

The new cultivar was originated from a hybridization made by the inventor in a controlled breeding program in Rijnsburg, The Netherlands in 1983. Both the male and the female parent were unnamed seedlings.

The new cultivar was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor in July 1983 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 1987 in a controlled environment in Rijnsburg, The Netherlands.

Horticultural examination of selected units has demonstrated that the combination of characteristics as herein disclosed for Marco Polo 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, any variation in 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 the new cultivar which in combination distinguish this lily as a new and distinct cultivar.

1. Distinctive overall very light pink flower color, with pink becoming stronger near the distal end and along the midvein of the tepal;

2. Large, generally upright flowers;

3. Reddish brown pollen contrasts well with light pink flower color;

4. Vigorous, tall plant height.

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, Marco Polo has lighter pink flower color, longer stems, semi-erect flowers, and the fragrance of Marco Polo is milder. When flowering is forced under natural light, Marco Polo produces an inflorescence approximately 12 days earlier than stargazer, under the same growing conditions. Marco Polo is fertile.

The accompanying photographic drawing shows typical flower characteristics of the new cultivar, with colors being as true as possible with illustrations of this type. The photograph illustrates several open flowers and buds at 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 1989-1990 and at Rijnsburg in July 1991.
