Latest Pelargonien-Fischer KG Patents:
The present invention comprises a new and distinct cultivar of geranium, botanically known as Pelargonium zonale, and hereinafter referred to by the cultivar name Schone Helena.
Schone Helena is a product of planned breeding program which had the objective of creating new geranium cultivars with salmon flower color, semi-double flower form, short plant height, fast rooting, good branching, and durable flowers.
Schone Helena was originated from a hybridization made in a controlled breeding program in Hillscheid, Federal Republic of Germany in 1979. The female parent was an unpatented cultivar named Tany having porcelain rose color semi-double flowers, but inferior branching characteristics. The male parent of Schone Helena was the unpatented cultivar PAC.RTM. Lachsball, principally characterized by its salmon semi-double flowers, lack of zonation in the foliage, compact habit, and fast rooting.
Schone Helena was discovered and selected as one flowering plant within the progeny of the stated cross by Ingeborg Schumann on June 27, 1980 in a controlled environment in Hillscheid, Federal Republic of Germany.
The first act of asexual reproduction of Schone Helena was accomplished when vegetative cuttings were taken from the initial selection in January, 1981 in a controlled environment in Hillscheid, Federal Republic of Germany by a technician working under formulations established and supervised by Ingeborg Schumann. Horticultural examination of selected units initiated in the Spring of 1981 and continuing in 1982 has demonstrated that the combination of characteristics as herein disclosed for Schone Helena are firmly fixed and are retained through successive generations of asexual reproduction.
Schone Helena 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. The following observations, measurements, and comparisons describe plants grown in Hillscheid, Federal Republic of Germany 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 Schone Helena which in combination distinguish this geranium as a new and distinct cultivar:
1. Porcelain rose flower color.
2. Large flowerhead (umbel).
3. Zoned leaves.
4. Very fast rooting.
5. Schone Helena can be cultivated below 12.degree. C.
6. EXcellent branching, producing an average of 4.2 branches per plant.
7. Medium to dark green foliage color.
8. Stable peduncles.
9. Chlorophyll quality excellent for transportation.
Of the many commercial cultivars known to the present inventor, the most similar in comparison to Schone Helena are the unpatented cultivars Salmon Irene and Springtime Irene. Reference is made to attached Chart A which compares certain characteristics of Schone Helena to those same characteristics of Salmon Irene and Springtime Irene. In general comparison to Salmon Irene, Schone Helena has faster rooting, better branching, shorter internode length, and shorter plant height. In comparison to Springtime Irene, Schone Helena has smaller leaves, lighter flower color, better weather resistance, better branching, and faster rooting.
The accompanying photographic drawings show typical flower and foliage characteristics of Schone Helena, with colors being as true as possible will illustrations of this type. Sheet 1 is a perspective view of a potted plant of the new cultivar. Sheet 2 is a relatively enlarged view of the flowers, buds and foliage, and sheet 3 is a black and white print of the underside of typical foliage of the new cultivar.
In the following description color references are made to The Royal Horticultural Society Colour Chart, except where additional or alternative values from Horticultural Colour Chart (H.C.C.) are indicated. The color values were determined between 3:40 and 3:50 P.M. on Aug. 12, 1983 under 20,000 Klux at Hillscheid, Federal Republic of Germany.
