USPP18166P2 - Chrysanthemum plant named ‘Lydia’ - Google Patents

Abstract

A chrysanthemum plant named ‘Lydia’ characterized by its medium sized blooms with yellow ray florets and a yellow center, with prolific branching; blooming for a period of 5 weeks.

Description

Latin name of the genus species: Chrysanthemum morifolium L.

BACKGROUND OF THE INVENTION

‘Lydia’ is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new chrysanthemum cultivars with a decorative type flower, a natural flowering date late in autumn; blooming for a period of 5 weeks. The new plant of the present invention comprises a new and distinct cultivar of chrysanthemum plant; ‘Lydia’ is a seedling resulting from a crossing program, set up by a previous breeder, and which records are unknown to the inventor. The new and distinct cultivar was discovered and selected as a flowering plant by Mark Roland Boeder on a cultivated field in Rijsenhout, The Netherlands in 2001. The first act of asexual production of ‘Lydia’ was accomplished when vegetative cuttings were taken from the initial selection in 2001 and propagated further in a controlled environment in Rijsenhout, The Netherlands. The new cultivar has been found to retain its distinctive characteristics through successive propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum (grown indoor) 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 various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

This new variety of chrysanthemum is of the botanical classification Chrysanthemum morifolium L. The observations and measurements were gathered from plants grown indoor in a greenhouse in Rijsenhout, The Netherlands; a complete analysis of the performance outdoor has not yet been made. After rooting, one cutting was planted in a container of 18 cm diameter in week 1 in 2006. Short-day treatment of 11L:13D started in week 5. Temperature of the greenhouse ranges from 18 to 22° C.; growth retardant alar was supplied at a dose of 1 g/l in week 8. The average height of the plants was 18 cm. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought tolerance. This new variety produces medium sized blooms with yellow ray florets and a yellow center.

From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Lydia’ is “Cronus” (U.S. Plant Pat. No. 14,563). When “Cronus” and ‘Lydia’ are being compared the following difference is noticed: The difference of “Cronus” and ‘Lydia’ are (1) Natural season blooming date. (2) Flower type. And (3) Color ray florets. (1) Plants of ‘Cronus’ flower in early autumn, while those of ‘Lydia’ in late autumn. (2) Plants of ‘Cronus’ have double type flowerheads, while ‘Lydia’ flowers are of single type. (3) The ray florets of ‘Lydia’ are more pale yellow than those of ‘Cronus’.

The following is a description of the plant and characteristics that distinguish ‘Lydia’ 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, edition 2001.
