Variety of geranium named `Lachsball`

Abstract

A new geranium cultivar is distinguished by its soft, pinkish-salmon color, short and compact plant, more basil branching, close internodes, smaller and lighter colored leaves with the flowers positioned closer to the foliage. In addition, early flowering is a distinguishing characteristic.

Description

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Pelargonium hortorum, Bailey known by the varietal name of Lachsball. The new variety was discovered in a selective breeding program and is a seedling resulting from the cross of the seed parent Rubin and the pollen parent Adonis.times.Hannchen Ander.

The new cultivar was discovered in the year 1980 in Dresden, German Democratic Republic; was first asexually reproduced by cuttings in Dresden, German Democratic Republic and has been repeatedly asexually reproduced by cuttings at Oglevee Floral Company in Connellsville, Pa. over an eighteen month period. It has been trialed and field tested at Connellsville during the summers of 1981 and 1982. It has been found to retain its distinctive characteristics through successive propagation.

The new cultivar, when grown in a greenhouse in Connellsville, Pa., using natural light and 62.degree. F. night temperature and 70.degree. F. day temperature, has a response time of five weeks from a well rooted cutting to a flowering plant in a four inch (10 cms.) pot.

DESCRIPTION OF THE NEW PLANT

The following detailed descriptions set forth the characteristics of the new cultivar. The data which define these characteristics were collected from asexual reproductions carried out by the Oglevee Floral Company in Connellsville, Pa. The plant history was taken on five weeks plants, blossomed under natural light in a greenhouse and color readings were taken indoors under 100 foot candles of cool, white fluorescent light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.

The following evaluation is a result of the trialing and field testing carried out in the summer of 1982 at Connellsville, Pa. and compares the new geranium cultivar to the standard cultivar "Penny" presently commercialized in the United States. The ratings are taken on plants planted in June and evaluated as to height, flowering, number of flowers, heat tolerance and form. The rating is based on a weighted average. A rating of 1.0 is poor and a rating of 10.0 is outstanding.

The new cultivar is characterized by its soft, pinkish-salmon color and its short and compact plant. There is more basil branching, close internodes and smaller and lighter colored leaves as compared with the standard bush zonal geraniums produced in the United States. Flowers are positioned closer to the foliage thereby rendering the plants very resistant to wind and rain damage. The cultivar is further characterized by its early flowering and its excellent disease resistance.

The new cultivar has been fingerprinted by the U.S. Department of Agriculture, Florist and Nursery Crops Laboratory, Beltsville, Md. Young plants arrived from Oglevee Floral Company of Connelsville, Pa. and were grown under standard conditions in a greenhouse at Beltsville, Md. The fingerprinting was conducted by high pressure liquid chromatographic analysis of the anthocyanin and flavonol chemical markers utilizing flower petals as an adjunct for cultivar identification. Petals were selected for analysis from individual mature flowers sampled just after anthesis. It should be noted that changes in environment can influence the biosynthesis of the flavonoids. The absorption profiles (fingerprints) are illustrated in FIGS. 2 and 3.
