Abstract

A new and distinct aneuploid (2n=43) moderately tall Hippeastrum hybrid plant named ‘Orlando’ measuring approximately 13-14.5 cm long, approximately 14-16 cm wide laterally, approximately 17-19 cm wide dorsal-ventrally. The flowers are densely striated pink-purple approximately RHS Red Purple 66A on their upper surfaces, with a broad white RHS 155D keel.

Description

Latin name of the genus and species of the plant claimed: ‘Orlando’ is a new amaryllis plant that is a Hippeastrum Herb.
Variety denomination: The amaryllis plant claimed is of the variety denominated ‘Orlando’, Hippeastrum Herb.
BACKGROUND OF THE INVENTION
The present invention is a new and distinct complex hybrid of Hippeastrum Herb., commonly known as amaryllis, a member of the family Amaryllidaceae, and is henceforth referred to by the cultivar name ‘Orlando’.
‘Orlando’ originated as a cross made by the inventor in 2001 as part of a breeding program in Miami, Fla., USA. The objectives of the breeding program are to develop new amaryllis varieties with novel floral form and coloration and heat tolerance. The female parent is a proprietary selection of the complex cross (Hippeastrum ambiguum×H. papilio)×H. brasilianum labeled with the breeder's code 101-5. The pollen parent is the non-patented commercial Hippeastrum ‘Wonderland’.
The new cultivar was selected on the basis of large flowers with deep pink-purple coloration contrasted by a broad median white stripe on the tepals. Over the course of seven years of evaluation, ‘Orlando’ has shown excellent heat resistance, grown under ambient conditions in Orlando, Fla. under 50% shade, and resistance to Red Scorch fungus (Staganospora curtisii).
Asexual reproduction of the new cultivar by twin-scale cuttings taken in a controlled environment in Miami, Fla. has shown that the unique features of this new amaryllis are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Orlando’. It is contrasted with its parents in Table 1. These characteristics in combination distinguish ‘Orlando’ as a new and distinct cultivar: 1) Deep cerise pink color, RHS 66A, of the tepals with very bold white, RHS 155D, stripe along keels.

Of the numerous commercial cultivars of amaryllis familiar to the inventor, the most similar to the new Hippeastrum ‘Orlando’ is Hippeastrum ‘Wonderland’ (unpatented), from which ‘Orlando’ differs by its larger flowers, the cerise pink (approximately RHS Red Purple 66A) color of the tepals, and the broader and more pronounced white, RHS 155D, stripes along the keel of the flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
FIGS. 1A and 1B are gray scale pictures of the flowers of Hippeastrum hybrid ‘Orlando’ showing the locations of colorimeter readings in Table 2 below.
FIGS. 2 and 3 are photographs of the flower of Hippeastrum hybrid ‘Orlando’.
 DETAILED BOTANICAL DESCRIPTION
The cultivar Orlando has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
Color descriptions below are based on evaluations with a Minolta CR-400 colorimeter at CIE D65/20 illumination/viewer conditions. The color parameters correspond to the uniform color space CIELAB, derived from Gonnet (Journal of Horticultural Science, Volume 68, 499-510, 1993; Food Chemistry, Volume 63, 409-415, 1998). Two color coordinates, a* and b*, as well as a psychometric index of lightness, L*, are defined. The L* is a measurement of luminosity, i.e., the equivalence of each color on the gray scale, ranging from 0 (black) to 100 (white). The a* takes positive values (0 to +60) for reddish colors and negative values (0 to −60) for the greenish ones, whereas the b* takes positive values (0 to +60) for yellowish colors and negative values (0 to −60) for the bluish ones. This is much more precise and repeatable analysis of color than obtained by using color charts (Ayala-Silva and Meerow, Proc. Intl. Trop. Hort. Soc., Volume 50, 138-144, 2006). The colorimeter takes three consecutive measurements of each sample, which was repeated three times, thus each set of color coordinates obtained are means of nine measurements. Where a reasonably close match could be discerned, The R.H.S. Colour Chart (Royal Horticultural Society, London, England, 1966) is also referenced.
