USPP10654P - Asiatic hybrid lily plant named `Helios` - Google Patents

Abstract

A new and distinct upright Asiatic lily hybrid named `Helios` having numerous, large bright yellow flowers, large yellow buds, high bud count, and strong stems with good foliage quality excellent for cut flowers.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar flowering of lily hybrid referred to commercially as an upright Asiatic hybrid lily and given the cultivar name `Helios`.

This invention was developed by controlled breeding in Aurora, Oreg. using A-080-78, a proprietary, non-released plant as the seed parent and A-034-84, another proprietary, non-released plant as the pollen parent.

This invention 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 traits have been repeatedly observed and are determined to be the basic characteristics of this invention which in combination distinguish this lily as a new and distinct cultivar: (1) large, bright, clear yellow flowers with no spots; (2) large, yellow buds; (3) high bud count; (4) long lasting flowers; (5) strong stems with good quality foliage; (6) good vase life; and (7) early flowering. Bulbs of this plant may be precooled and forced out of season for uniform cut flower production. In addition, this new lily shows good disease and virus resistance.

Compared to `London,` this invention has no spots, better yellow color, better substance, stronger stems, and better bud color.

Asexual reproduction of this new variety has been accomplished at Cebeco Lilies, Inc., Aurora, Oreg. by scaling and tissue culture. The resulting plants have shown that the abovementioned unique features are stable and reproduce true to type in each successive propagation.

DESCRIPTION OF THE DRAWING

FIG. 1 is a close-up photograph which illustrates in greater detail a single flower of the new plant.

FIG. 2 is a photograph showing the `Helios` lily.

The photographs of the drawing were taken in Jun. 1995 in a studio and illustrate the typical flower and foliage form, with color as true as reasonably possible in this type of the color photograph.
