Abstract

This invention relates to a new and distinct cultivar of regal pelargonium (Pelargonium×domesticum) named `Crystal` substantially as illustrated and described herein, particularly characterized as being compact and self-branching, early flowering and floriferous, exhibiting excellent postharvest keeping quality, and having white flowers with distinctive red feathering on the upper two petals thereof.

Description

The present invention relates to a new and distinct cultivar of regal pelargonium (Pelargonium×domesticum) called `Crystal`. This cultivar is very compact and self-branching (without pinching), early flowering and floriferous, with excellent postharvest keeping quality. The flowers are pure white with distinctive red feathering on the upper two petals.

The cultivar was developed from an organized, scientifically designed breeding program conducted at the Department of Horticulture. The Pennsylvania State University, University Park, Pa. 16802. The objective was to produce a new regal pelargonium genotype with excellent propagation characteristics, compact growth habit, predictable and consistent flowering response, and excellent postharvest quality. `Crystal` resulted from the selection from the progeny of the self-pollination of regal pelargonium cultivar `Virginia`. The selection was asexually propagated by cuttings and the reproductions ran true.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates in color the cultivar (cultivated with pinching) including foliage and flowers.

FIG. 2 illustrates in color primarily the floret.

With reference to the detailed description of the cultivar which follows, the test plant was potted in soilless medium and growth in a glasshouse under natural sunlight, at a night temperature of about 58° F. and a day temperature of about 68° F. Fertilizer was applied in every watering, with 200 ppm nitrogen provided in the forms of 15-16-17 (two consecutive waterings) and 20-0-20 (every third watering) in a repeating cycle.

Color readings were taken under incandescent light at approximately 200 foot candles and color identification was by reference to The Royal Horticultural Society Colour Charts, except where common terms of color definition are employed.
