USPP15727P3 - Chrysanthemum plant named ‘Redock Salmon’ - Google Patents

Abstract

A Chrysanthemum plant named ‘Redock Salmon’ characterized by its medium sized blooms with salmon ray-florets and yellow-green disc florets.

Description

Related cultivars: ‘Redock Salmon’ is related to ‘Redock Dark’ (pending Ser. No. 09/910,029) and ‘Redock Orange’ (pending Ser. No. 09/910,030). These varieties are all mutants of the original ‘Redock’ (unpatented).

BACKGROUND OF THE INVENTION

‘Redock Salmon’ is a product of a breeding and selection program that had the objective of finding color mutants of ‘Redock’. The new plant of the present invention comprises a new and distinct cultivar of chrysanthemum plant that is a natural occuring sport of a parent chrysanthemum named ‘Redock’ (unpatented). A comparison with parent chrysanthemum ‘Redock’ is also made in this application. The new cultivar was discovered as a whole plant mutation in September, 1999 by Rob Noodelijk in a controlled environment (greenhouse) in Rijsenhout, Holland. The first act of asexual reproduction of ‘Redock Salmon’ was accomplished when vegetative cuttings were taken from the initial selection in November, 1999 in Rijsenhout, Holland.

SUMMARY OF THE INVENTION

The present invention is a new and distinct variety of chrysanthemum bearing medium sized blooms with salmon ray-florets and yellow-green disc florets.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the foliage of the cultivar.

DESCRIPTION OF THE INVENTION

This new variety of chrysanthemum is of the botanical classification Chrysanthemum morifolium. The observations and measurements were gathered from plants grown in April/May in a greenhouse in Rijsenhout, Holland in a photo-periodic controlled crop under conditions generally used in commercial practice. The greenhouse temperatures during this crop were at day-time between 18° C. and 25° C. and at night 20° C. After a long day period of 14 days, the photo-periodic response time in this crop was 47 days. After the long day period to flowering, growth retardants were applied 3 times in an average dose of 2.5 gram/liter water. No tests were done on disease or insect resistance or susceptibility. This new variety produces medium sized blooms with salmon ray-florets and yellow-green disc-florets blooming on the plant for 4 weeks. This new variety of chrysanthemum has been found to retain its distinctive characteristics throughout successive propagations; however, the phenotype may vary significantly with variations in environment such as light intensity and temperature. To show the phenotype as described ‘Redock Salmon’ can be planted without assimilation lightning (high pressure sodium lamps) between week 50 and week 40 of the next year under greenhouse conditions in Holland. With assimilation light (minimum level 2500 lux) it can be planted year round under greenhouse conditions in Holland.

The difference between ‘Redock’ and its sport ‘Redock Salmon’ is flower color. From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Redock Salmon’ is ‘Redock Orange’. When ‘Redock Salmon’, ‘Redock Orange’ and ‘Redock’ are being compared the following differences and similarities are noticed: The difference of ‘Redock Orange’, ‘Redock Salmon’ and ‘Redock’ is the (1) ray-floret color. The color of ‘Redock Salmon’ is salmon, of ‘Redock Orange’ is orange and of ‘Redock’ is pink. All other characteristics of ‘Redock Orange’, ‘Redock Salmon’ and ‘Redock’ are similar.

From other commercial varieties ‘Salmon Reagan’ (U.S. Plant Pat. No. 8,769) is the most similar. The differences between ‘Salmon Reagan’ and ‘Redock Salmon’ are (1) Flower form and color. The ray-florets of ‘Redock Salmon’ are more upright, less broad, more pointed and more concave. (2) Vigour. Under the same circumstances the plants of ‘Redock Salmon’ are 20 cm longer. (3) Response time. The response time of ‘Redock Salmon’ is shorter. (4) The disc-floret size of ‘Redock Salmon’ is smaller. (5) Foliage size and color. The foliage of ‘Redock Salmon’ is bigger and more yellow-green.

The following is a description of the plant and characteristics that distinguish ‘Redock Salmon’ as a new and distinct variety. The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances. The color chart used in this description is: The Royal Horticultural Society Colour Chart, 1995 edition.
